systems.

i40evf and ixlv drivers renamed to iavf
---------------------------------------
The i40evf and ixlv drivers have been renamed to iavf. The i40evf and ixlv
drivers have been removed from this install media. The iavf drivers can be
found in the PROAVF directory of this install media.

Configuring SR-IOV for improved network security
================================================

In a virtualized environment, on Intel(R) Server Adapters that support SR-IOV,
the virtual function (VF) may be subject to malicious behavior.
Software-generated frames are not expected and can throttle traffic between the
host and the virtual switch, reducing performance. To resolve this issue,
configure all SR-IOV enabled ports for VLAN tagging. This configuration allows
unexpected, and potentially malicious, frames to be dropped.

Intel(R) ANS Teams and VLANs on Microsoft* Windows* 10
======================================================

If you are running Windows 10 Anniversary edition (RS1) you will need to
install Intel LAN software v22.1 or newer. If you are running Windows 10
Creators Update (RS2) you will need to install Intel LAN software v22.3 or
newer.
Note: If you are running Windows 10 Creators Update (RS2) and are using Intel
LAN software release v22.1 or v22.2, then ANS will not function until you
update to the Intel LAN software v22.3 or newer.

Operating System Support
========================

NOTE: Before performing a major OS upgrade, Intel recommends that you uninstall
the Intel PROSet feature, perform the OS upgrade, and then reinstall with the
latest version of Intel PROSet. This will ensure all features are available and
avoid potential issues.

NOTE: Microsoft* Windows Server* 2012 R2 is the last Windows Server operating
system version that supports Intel(R) Advanced Networking Services (Intel ANS).

NOTE: Intel(R) PROSet for Windows* Device Manager is not supported on
Microsoft* Windows Server* 2019 (and later) and Microsoft Windows* 10 Version
1809 (and later). Use Intel(R) PROSet Adapter Configuration Utility instead.
The installer will determine which utility to install based on the operating
system you are running.

Intel 10GbE Ethernet Adapters do not support Microsoft* Windows* 32-bit
operating systems. They support 32-bit versions of Linux* and FreeBSD*.

Even though the UEFI driver states that it supports "Intel(R) 40GbE" devices,
the driver supports all devices based on the Intel(R) X722, XXV710, X710, and
XL710 controllers, regardless of speed.

Drivers and Software for unsupported operating systems
------------------------------------------------------
The most recent software and drivers for unsupported operating systems can be
found on the Intel Customer Support website at
http://www.intel.com/support/go/network/adapter/home.htm

Some older Intel(R) Ethernet Adapters do not have full software support for the
most recent versions of Microsoft Windows*. Many older Intel Ethernet Adapters
have base drivers supplied by Microsoft Windows. Lists of supported devices per
OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Intel PROSet for Windows Device Manager on older operating systems
------------------------------------------------------------------
On systems running Microsoft Windows 7 and Microsoft Windows Server 2008 R2,
you must install the legacy version of Intel PROSet for Windows Device Manager.
If it is available on your install media, Autorun.exe will detect your
operating system and install the correct drivers and software. For manual
installs, the software and installers are on your install media in the
.\APPS\PROSETDX\Win32Legacy, .\APPS\PROSETDX\Winx64Legacy,
.\APPS\SETUP\SETUPBD\Win32Legacy, and .\APPS\SETUP\SETUPBD\Winx64Legacy
directories. Note that the legacy version of the software will not change on
every release.

Fibre Channel over Ethernet Support
-----------------------------------
FCoE is no longer supported and is no longer being tested. Installing drivers
from Release 23.2 or later may cause FCoE to behave unexpectedly or cease
functioning.

Support for new operating systems will not be added to FCoE. The last operating
system versions that support FCoE are as follows:

  * Microsoft Windows Server 2012 R2
  * Red Hat Enterprise Linux 7.2
  * Red Hat Enterprise Linux 6.7
  * Suse Linux Enterprise Server 11 SP4
  * Suse Linux Enterprise Server 12 SP1
  * VMware ESX 6.0

Installing Drivers and Intel(R) PROSet
======================================

You must have administrator rights to install or use Intel PROSet for Windows
Device Manager. Intel recommends the following procedure for installing drivers:
1) Cancel any Found New Hardware Wizard screens that open.
2) Start the autorun located on the CD or in your download directory.
3) Click "Install Drivers and Software" and follow the instructions in the
    install wizard.

Intel(R) PROSet functionality is integrated with the Windows Device Manager. To
configure Intel(R) Ethernet Adapters and Controllers, open the Windows Device
Manager. Do not open adapter, team, or VLAN properties from the network control
panel as you may be prompted to reboot your system.

You must upgrade PROSet when upgrading drivers. Failure to do so will result in
instability and missing tabs in Windows Device Manager. For software and driver
versions prior to Release 16.2, if you have Fibre Channel over Ethernet (FCoE)
boot enabled on any devices in the system, you will not be able to upgrade your
drivers. You must disable FCoE boot before upgrading your ethernet drivers.
This issue is resolved in Release 16.2 and beyond.

NOTE: Support for the Intel PROSet command line utilities (prosetcl.exe and
  crashdmp.exe) has been removed. This functionality has been replaced by
  the Intel(R) PROSet for Microsoft* Windows PowerShell* software. Please
   transition all of your scripts and processes to use the Intel PROSet
  for Microsoft Windows PowerShell software. Microsoft* Windows* 8.1
  and Windows Server* 2012 R2 are the last operating systems to support
  the Intel PROSet command line utilities.

Intel PROSet for Windows* Device Manager is not supported on the
following devices
----------------------------------------------------------------
* Intel(R) 82552 10/100 Network Connection
* Intel(R) 82567V-3 Gigabit Network Connection
* Intel(R) X552 10G Ethernet devices
* Intel(R) X552 Virtual Function devices
* Intel(R) X553 Ethernet devices
* Intel(R) X553 Virtual Function devices
* Any platform with a System on a Chip (SoC) processor that includes either
  a server controller (designated by an initial X, such as X552) or both a
  server and client controller (designated by an initial I, such as I218)
* Devices based on the Intel(R) Ethernet Controller X722
* Intel(R) X722 Virtual Function devices

Intel PROSet fails to install
-----------------------------
A possible cause could be the Windows Modules Installer service is disabled.
The installer for Intel PROSet requires this service. You can enable this
service from the Administrative Tools -> Component Services control panel.

User Guides
===========

Several user guides for Intel Network Connections are available for this
product. You may access them in the following ways:
- On Windows-based systems, start the autorun program on the Intel CD,
  then click "View User Guides".
- Double-click "index.htm" located in the root of the Intel CD.
- Go to http://support.intel.com.

Intel Fiber Optic Adapters
==========================

Caution: The fiber optic ports may utilize Class 1 or Class 1M laser devices.
Do not stare into the end of a fiber optic connector connected to a "live"
system. Do not use optical instruments to view the laser output. Using optical
instruments increases eye hazard. Laser radiation is hazardous and may cause
eye injury. To inspect a connector, receptacle or adapter end, be sure that the
fiber optic device or system is turned off, or the fiber cable is disconnected
from the "live" system.

The Intel Gigabit and 10GbE network adapters with fiber optic connections
operate only at their native speed and only at full-duplex. Therefore you do
not need to make any adjustments. Use of controls or adjustments or performance
of procedures other than those specified herein may result in hazardous
radiation exposure. The laser module contains no serviceable parts.

Saving and Restoring Adapter Settings in Microsoft Windows
operating systems
==========================================================

You can save and then restore adapter settings using the Microsoft* Windows
PowerShell* script, SaveRestore.ps1. You must have Administration privileges to
run scripts. If you do not have Administration privileges, you will not receive
an error; the script just will not run. Only adapter settings are saved
(including ANS teaming and VLANs). The adapter's driver is not saved. Restore
using the script only once. Restoring multiple times may result in unstable
configuration. The Restore operation requires the same OS as when the
configuration was saved.

NOTE: Intel(R) PROSet for Windows* Device Manager must be installed for
  SaveRestore.ps1 to run. Also, for systems running a 64-bit OS, be sure
  to run the 64-bit version of Windows PowerShell, not the 32-bit (x86)
  version, when running the SaveRestore.ps1 script.

NOTE: Support for the SaveResDX.vbs script is being removed. Please transition
  all of your scripts and processes to Microsoft Windows PowerShell.

Major Operating system upgrades and saving your configuration
-------------------------------------------------------------
Your network device settings, including teams and VLANs, are not saved when you
upgrade your operating system. You must reinstall your network drivers and
software and reconfigure your network devices. This applies for upgrading from
one version of Microsoft Windows to another, not applying a service pack.

Teaming Notes
=============
Intel devices that are not supported by Intel(R) PROSet can still be added to
teams. These devices are supported by the Multi-Vendor Teaming functionality of
ANS teams.

Microsoft Server 2012 NIC Teaming (LBFO)
----------------------------------------
Intel(R) Advanced Network Services (ANS) teaming and VLANs are incompatible
with Microsoft Server 2012 NIC Teaming (LBFO). Do not create an LBFO team using
ports that are part of an ANS team or ANS VLAN.

DCB is not compatible with Microsoft Server 2012 NIC Teaming (LBFO)
-------------------------------------------------------------------
Data Center Bridging (DCB) is incompatible with Microsoft Server 2012 NIC
Teaming (LBFO). Do not create an LBFO team using Intel 10G ports when DCB is
installed. Do not install DCB if Intel 10G ports are part of an LBFO team.
Install failures and persistent link loss may occur if DCB and LBFO are used on
the same port. Installing Microsoft's Hot fix KB 2818790 will resolve the
issue. This issue only affects Microsoft Windows Server 2012.

RLB is not supported when a team is added to a virtual NIC
----------------------------------------------------------
Virtual NICs cannot be created on a team with Receive Load Balancing enabled.
Receive Load Balancing is automatically disabled if you create a virtual NIC on
a team.

Team setup requirement
----------------------
Before creating a team, make sure each adapter is configured similarly. Check
each adapter's settings in Intel PROSet. Settings to check include QoS Packet
Tagging, Jumbo Frames, and the various offloads. If team members implement
Advanced features differently, the team will align the settings with the least
capable adapter.

Changing Offload Settings for an Adapter in an ANS Team
-------------------------------------------------------
When you disable an offload setting for an adapter in an ANS team, the team
reloads and the team capabilities are recalculated. As a result, the offload
setting is disabled for the remaining adapters in the ANS team. Intel PROSet
does not reflect the fact that the offload setting is disabled for the
remaining adapters in the team.
If you re-enable the offload setting for the original adapter in the team, the
settings will not be applied until the system is rebooted or the team is
reloaded.

IEEE 802.3ad teaming on Cisco trunks
------------------------------------
When implementing 802.3ad teams on Cisco switch ports in trunking mode, set the
native/untagged VLAN for these ports to ID 1. Otherwise, you may experience
traffic loss or lack of failover between aggregators. See your Cisco
documentation for information about setting the native VLAN ID.

Teaming Known Issues
--------------------

Unexpected performance drop or disabled ANS team member
-------------------------------------------------------
Using non-Intel cmdlets, such as the Set-NetAdapterAdvancedProperty cmdlet
provided in Microsoft PowerShell*, to change settings for an ANS-teamed adapter
may cause the team to stop using that adapter to pass traffic. You may see this
as reduced performance or the adapter being disabled in the PROSet Teaming GUI.
You can repair the issue by changing the setting back to its previous state, or
by removing the adapter from the ANS team and then adding it back.

Network Connections window shows the team as disabled or network
cable unplugged
----------------------------------------------------------------
After adding a VLAN to the team, this is normal. The connection protocols are
now bound to the VLAN on the team. You can configure the connection protocols
in the Properties for the VLAN.

Team name doesn't change in Device Manager
------------------------------------------
If you modify a team name from the team property sheet, it may take several
minutes for the name to change in Device Manager. Closing and opening Device
Manager will load the new name.

Removing a teamed adapter from a hot-plug system
------------------------------------------------
When you physically remove an adapter that is part of a team or a VLAN, you
must reboot or reload the team/VLAN before using that adapter in the same
network. This will prevent Ethernet address conflicts.

VLANs remain after team removal
-------------------------------
When you remove a team, some of the VLANs bound to that team may remain. You
can manually remove the VLANs to correct the issue.

Changing speed and duplex of adapters in a team
-----------------------------------------------
When you add an adapter to a Link Aggregation team using Intel PROSet, make
sure that the adapter is running at the same speed and duplex of the other
adapters in the team.

Compatibility notes for Multi Vendor Teaming
--------------------------------------------
Attempting to hot-add a non-Intel adapter to a team may cause system
instability. If you do hot-add a non-Intel adapter to a team, make sure you
restart the computer or reload the team.

IEEE 802.3ad teaming with Foundry switches
------------------------------------------
Foundry switches require an even number of ports in an aggregated link. If you
remove an adapter from an 802.3ad team connected to a Foundry switch, make sure
you maintain an even number of adapters in the team.

Jumbo Frames and Jumbo Packets
==============================

Jumbo Frames and MACSec are not compatible on the Intel(R) 82579LM and Intel(R)
82579V Network Connections. If MACSec is enabled on a platform containing
either part, you will not be able to enable Jumbo Frames on the connection.

Limited Jumbo Frame Size
------------------------
Some Intel gigabit adapters and connections that support Jumbo Frames have a
frame size limit of 4K bytes. The following devices have this limitation:
  Intel(R) 82577LM Gigabit Network Connection
  Intel(R) 82578DM Gigabit Network Connection

The following devices do not support jumbo frames:
  Intel(R) PRO/1000 Gigabit Server Adapter
  Intel(R) PRO/1000 PM Network Connection
  Intel(R) 82562V 10/100 Network Connection
  Intel(R) 82562GT 10/100 Network Connection
  Intel(R) 82566DM Gigabit Network Connection
  Intel(R) 82566DC Gigabit Network Connection
  Intel(R) 82566DC-2 Gigabit Network Connection
  Intel(R) 82562V-2 10/100 Network Connection
  Intel(R) 82562G-2 10/100 Network Connection
  Intel(R) 82562GT-2 10/100 Network Connection
  Intel(R) 82567LF Gigabit Network Connection
  Intel(R) 82567V Gigabit Network Connection
  Intel(R) 82567LF-2 Gigabit Network Connection
  Intel(R) 82567V-2 Gigabit Network Connection
  Intel(R) 82567LF-3 Gigabit Network Connection
  Intel(R) 82552 10/100 Network Connection
  Intel(R) 82577LC Gigabit Network Connection
  Intel(R) 82578DC Gigabit Network Connection
  Intel(R) 82567V-3 Gigabit Network Connection
  Intel(R) 82567V-4 Gigabit Network Connection

The Intel PRO/1000 PL Network Connection supports jumbo frames in Microsoft*
Windows* operating systems only when Intel(R) PROSet for Windows Device Manager
is installed.

Power Management and System Wake
================================

Not all systems support every wake setting. There may be BIOS or Operating
System settings that need to be enabled for your system to wake up. In
particular, this is true for Wake from S5 (also referred to as Wake from power
off). Microsoft Windows 7 and Windows Server 2008 R2 do not support Wake on
directed packet. Systems with these operating systems will not wake on a ping
or other directed packet.

System does not wake when expected
----------------------------------
Under Microsoft Windows 7 or Windows Server 2008 R2, the system may not wake
when sent an ARP packet. Forcing your system into Home Networking mode (instead
of work or public mode) will resolve the issue. You can set the network mode
during install or from the Networking Control Panel.
However, if the network is disconnected and reconnected, and a DHCP server is
not available or if there is no default gateway defined, it appears to the
operating system that the network is undefined and the OS will reset it to
public.

Under Microsoft Windows Server 2012, the system may not wake even though Wake
on LAN settings are enabled. Disabling Fast Startup in the operating system
should resolve the issue.

System does not wake on link
----------------------------
On a driver-only installation, if you change 'Wake on Link Settings' to Forced
and change 'Wake on Magic Packet' and 'Wake on Pattern Match' to Disabled, the
system may not wake up when expected. In order to "Wake on Link" successfully,
check the Power Management tab and make sure that "Allow this device to wake
the computer" is checked. You may also need to change 'Wake on Magic Packet' or
'Wake on Pattern Match' to Enabled.
On Microsoft* Windows* 7, or later, you must enable Wake on Magic Packet or
Wake on Pattern Match for Wake on Link to function properly.

Directed Packets may not wake the system
----------------------------------------
On some systems, quad port server adapters may not wake when configured to wake
on directed packet. If you experience problems waking on directed packets, you
must configure the adapter to use Magic Packets*.

Power Management options are unavailable or missing
---------------------------------------------------
If you install only the base drivers, later install Intel(R) PROSet for Windows
Device Manager, then remove Intel PROSet, the settings on the Power Management
tab on the Adapter Property Sheet may be unavailable or missing altogether. You
must reinstall Intel PROSet to resolve the issue.

Low power link speed slower than expected
-----------------------------------------
If you disable the "Reduce Power During Standby" setting and remove power from
the system, your system may link at 10Mbps when power is restored, instead of
100Mbps or faster. The system will continue to link at 10Mbps until the
operating system is loaded. This setting will be restored when the OS loads.

System Wakes Unexpectedly
-------------------------
On a driver only install, if you uncheck the "Allow this device to bring the
computer out of standby" option on the Power Management tab, the adapter will
still wake the system from Standby or Hibernate. The "Wake on Settings" option
on the Advanced tab must also be set to Disabled.

Auto Connect Battery Saver (ACBS) enabled NICs do not power up when
connected back to back
-------------------------------------------------------------------
If you have two systems, both running on batteries and both with ACBS-enabled
NICs that are in an ACBS state, and you connect them back to back, the NICs
will not power up. Since both NICs are powered down, neither one can generate a
link signal to wake the other. Either connect AC power to one system or disable
ACBS to resolve this issue.

Auto Connect Battery Saver (ACBS) does not function
---------------------------------------------------
ACBS will not function on an adapter if the adapter has forced speed or duplex
settings. ACBS will only function if the adapter is set to auto-detect or
auto-negotiate.

Wake on LAN is unavailable
--------------------------
Wake on LAN is supported on port A only on the following devices:
- Intel(R) PRO/1000 GT Quad Port Server Adapter
- Intel(R) PRO/1000 PT Quad Port Server Adapter
- Intel(R) PRO/1000 PT Dual Port Network Connection
- Intel(R) PRO/1000 PT Dual Port Server Connection
- Intel(R) PRO/1000 PT Dual Port Server Adapter
- Intel(R) PRO/1000 PF Dual Port Server Adapter
- Intel(R) PRO/1000 PT Quad Port LP Server Adapter
- Intel(R) PRO/1000 PF Quad Port Server Adapter
- Intel(R) Gigabit ET2 Quad Port Server Adapter
- Intel(R) Ethernet Server Adapter I340-T4
- Intel(R) Ethernet Server Adapter I340-T2
- Intel(R) Gigabit ET Quad Port Server Adapter
- Intel(R) Gigabit EF Dual Port Server Adapter
- Intel(R) Gigabit ET Dual Port Server Adapters
- Intel(R) Gigabit VT Quad Port Server Adapter
- Intel(R) Ethernet Server Adapter I340-F4
Wake on LAN is not supported on any port of the following devices:
- Intel(R) Ethernet Converged Network Adapter X710
- Intel(R) Ethernet Converged Network Adapter X710-2
- Intel(R) Ethernet Converged Network Adapter X710-4
- Intel(R) Ethernet Converged Network Adapter X710-T
- Intel(R) Ethernet Converged Network Adapter X710-T4
- Intel(R) Ethernet Converged Network Adapter XL710-Q1
- Intel(R) Ethernet Converged Network Adapter XL710-Q2
- Intel(R) Ethernet Network Adapter X710-T2L
- Intel(R) Ethernet Network Adapter X710-T4L
- Intel(R) Ethernet Network Adapter X710-TL

Most Intel 10GbE Network Adapters do not support Wake on LAN on any port. The
Intel(R) Ethernet Converged Network Adapter X550-T1 and Intel(R) Ethernet
Converged Network Adapter X550-T2 have a manageability/AUX power connector.
These devices only support WoL if AUX power is supplied via this connector.
Note that this is system and adapter specific. Some with this connector do not
support WoL. Some systems do not provide the correct power connection. See your
system documentation for details.

System Wakes-Up from a Removed VLAN
-----------------------------------
If a system goes into standby mode, and a directed packet is sent to the IP
address of the removed VLAN, the system will wake-up. This occurs because a
directed packet bypasses VLAN filtering.

Intel Network Adapters ignore consecutive Wake Up signals while
transitioning into standby mode
---------------------------------------------------------------
While sending a system into standby, occasionally a wake up packet arrives
before the system completes the transition into standby mode. When this
happens, the system ignores consecutive wake up signals and remains in standby
mode until manually powered up using the mouse, keyboard, or power button.

Link flap when Energy Efficient Ethernet is enabled
---------------------------------------------------
Some switches do not support Energy Efficient Ethernet (EEE) correctly. Make
sure your switch is loaded with the latest firmware. Disabling EEE on your
adapter may resolve this issue.

Microsoft Windows* 8.1 and Windows Server* 2012 R2 Notes
========================================================

Some older Intel(R) Ethernet Adapters do not have full software support for the
most recent versions of Microsoft Windows*. Many older Intel Ethernet Adapters
have base drivers supplied by Microsoft Windows. Lists of supported devices per
OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Encapsulated traffic may fail when traffic is tagged and 'Packet
Priority & VLAN' option is disabled
----------------------------------------------------------------
If the 'Packet Priority & VLAN' advanced parameter is set to "Disabled," VLAN
tagged packets will have incomplete destination information and may be dropped
by the physical switch. To ensure encapsulated traffic is not dropped, verify
that the 'Packet Priority & VLAN' advanced parameter is set to "Enabled."

Virtual Machine Queues are not allocated until reboot
-----------------------------------------------------
On a Microsoft Windows Server 2012 R2 system with Intel(R) Ethernet Gigabit
Server adapters installed, if you install Hyper-V and create a VM switch,
Virtual Machine Queues (VMQ) are not allocated until you reboot the system.
Virtual machines can send and receive traffic on the default queue, but no VMQs
will be used until after a system reboot.

Link loss after changing the Jumbo Frames setting
-------------------------------------------------
Inside a guest partition on a Microsoft Windows Server 2012 R2 Hyper-V virtual
machine, if you change the jumbo frame Advanced setting on an Intel(R) X540
based Ethernet Device or associated Hyper-V NetAdapter, you may lose link.
Changing any other Advanced Setting will resolve the issue.

DCB QoS and Priority Flow Control do not act as expected
--------------------------------------------------------
If you use Microsoft's Datacenter Bridging (DCB) implementation configure
Quality of Service (QoS) and Priority Flow Control (PFC), the actual traffic
flow segregation per traffic class may not match your configuration and PFC may
not pause traffic as expected. If you mapped more than one priority to a
Traffic Class, enabling only one of the priorities and disabling the others
will work around the issue. Installing Intel's DCB implementation will also
resolve this issue.
This issue affects Microsoft Windows Server 2012 and Server 2012 R2.

Microsoft* Windows Server* 2012 Notes
=====================================

Some older Intel(R) Ethernet Adapters do not have full software support for the
most recent versions of Microsoft Windows*. Many older Intel Ethernet Adapters
have base drivers supplied by Microsoft Windows. Lists of supported devices per
OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Hot plug operations do not work as expected in the following reference designs:
Foxcove - Hot plug operations do not work.
Emerald Ridge - Hot plug operations work only if you have the latest BIOS.

In Intel(R) PROSet for Windows Device Manager, the help text may not initially
be displayed. The text should appear after switching between tabs a few times
in Intel(R) PROSet.

DCB QoS and Priority Flow Control do not act as expected
--------------------------------------------------------
If you use Microsoft's Datacenter Bridging (DCB) implementation configure
Quality of Service (QoS) and Priority Flow Control (PFC), the actual traffic
flow segregation per traffic class may not match your configuration and PFC may
not pause traffic as expected. If you mapped more than one priority to a
Traffic Class, enabling only one of the priorities and disabling the others
will work around the issue. Installing Intel's DCB implementation will also
resolve this issue.
This issue affects Microsoft Windows Server 2012 and Server 2012 R2.

Microsoft Windows* 7 and Windows Server* 2008 R2 Notes
======================================================

Microsoft Windows 7 and Windows Server 2008 R2 do not support Wake on directed
packet. Systems with these operating systems will not wake on a ping or other
directed packet.

Some older Intel(R) Ethernet Adapters do not have full software support for the
most recent versions of Microsoft Windows*. Many older Intel Ethernet Adapters
have base drivers supplied by Microsoft Windows. Lists of supported devices per
OS are available at:
http://www.intel.com/support/go/network/adapter/nicoscomp.htm

Flow Control is off by default
------------------------------
The inbox drivers for Intel network devices in Windows 7 and Windows Server
2008 R2 have flow control turned off by default.

Intel(R) 710 Series Network Controller Notes
============================================

In order for an Intel(R) 40GbE Network Adapter to reach its full potential, you
must install it in a PCIe Gen3 x8 slot. Installing it in a shorter slot, or a
Gen2 or Gen1 slot, will impact the throughput the adapter can attain.

Some Intel(R) 710 series based devices report a subvendor ID of 0x0000 and may
display a generic branding string. Port 0 reports the correct subvendor ID and
displays the correct branding string.

Intel 710 series based devices may maintain link on any and all ports as long
as power is provided to the device, regardless of the device's or system's
power state.

Intel 710 series based devices do not support Microsoft Windows Server 2008R2
or Windows Server 2012 as SR-IOV Guest operating systems. These devices do not
support Windows Server 2012 as the SR-IOV Host operating system. They also do
not support Linux as the SR-IOV guest operating system on any Microsoft Windows
Server Hyper-V Host.

SFP+ and QSFP+ Devices:

See the link below for information on supported media for X710/XL710/XXV710
based devices:
  http://www.intel.com/content/dam/www/public/us/en/documents/release-notes/
  xl710-ethernet-controller-feature-matrix.pdf
NOTES:
* Some Intel branded network adapters based on the X710/XL710 controller
  only support Intel branded modules. On these adapters, other modules
  are not supported and will not function.
* For connections based on the 710 series controller, support is dependent
  on your system board. Please see your vendor for details.
* In all cases Intel recommends using Intel optics; other modules may function
  but are not validated by Intel. Contact Intel for supported media types.
* In systems that do not have adequate airflow to cool the adapter and
  optical modules, you must use high temperature optical modules.

Intel ANS VLANs adversely affect performance
--------------------------------------------
Intel ANS VLANs adversely affect the performance of 710 series based devices.
Use the networking features built into Microsoft Windows Server 2012, or other
server management software, to assign VLANs.

Diagnostic button disabled
--------------------------
When part of an Intel(R) ANS team, devices based on the Intel X710/XL710
controller do not support diagnostics. Support will be added in a future
release.

Traffic is not passed between Virtual NICs
------------------------------------------
SR-IOV Virtual Functions are unable to send or receive traffic between Virtual
NICs on the same physical port or between emulated connections on a Linux
Software bridge and connections that use SR-IOV VFs. Use an external switch
that is 802.1Qbg (VEPA) capable to workaround this issue.

Intel 10GbE Network Adapter Notes
=================================

Release 18.7 is the last release in which Intel 10GbE Network Adapters support
32-bit Microsoft Windows. Starting with Release 18.8, Intel 10GbE Network
Adapters only support 64-bit operating systems.

Devices based on the Intel(R) Ethernet Connection X552 and Intel(R) Ethernet
Connection X553 do not support the following features:

Attaching the cable to the Intel(R) 10 Gigabit AF DA Dual Port Server Adapter
may require significant force. The cable must be latched in for proper
operation.

When 82599-based SFP+ devices are connected back to back, they should be set to
the same Speed/Duplex setting. Results may vary if you mix speed settings.

Some Intel(R) 10 Gigabit Network Adapters and Connections support SFP+
pluggable optical modules.

82599-Based Adapters
NOTES:
* If your 82599-based Intel(R) Network Adapter came with Intel SFP+ optics, or

Intel 10GbE Network Adapter Known Issues
-----------------------------------------

ETS Bandwidth Allocations Don't Match Settings
----------------------------------------------
When Jumbo Frames is set to 9K with a 10GbE adapter, a 90%/10% ETS traffic
split will not actually be attained on any particular port, despite settings
being made on the DCB switch. When ETS is set to a 90%/10% split, an actual
observed split of 70%/30% is more likely.

Supported SFP, SFP+, or QSFP+ module not recognized by the system
-----------------------------------------------------------------
If you try to install an unsupported module, the port may no longer install any
subsequent modules, regardless of whether the module is supported or not. The
port will show a yellow bang under Windows Device manager and an event id 49
(unsupported module) will be added to the system log when this issue occurs. To
resolve this issue, the system must be completely powered off.

Lower than expected performance on quad port 10GbE devices
----------------------------------------------------------
All SFP and QSFP quad port NICs based on the 82599 controller will link at 5
GB/s (PCIe gen2) when used in a system from Intel's Enterprise Platforms and
Services Division (EPSD). The PLX PCIe switch used on these NICs is not on the
EPSD white list of supported PCIe gen3 devices. Devices not on the white list
are blocked from linking at PCIe gen3 by the production BIOS.

Lower than expected performance on quad port 10GbE devices
----------------------------------------------------------
Quad port 10Gbe devices require x8 PCIe gen 3 slots. Full throughput is not
possible in a PCIe gen 2 slot.

Lower than expected performance on dual port 10GbE devices
----------------------------------------------------------
Some PCIe x8 slots are actually configured as x4 slots. These slots have
insufficient bandwidth for full 10Gbe line rate with dual port 10GbE devices.
The driver can detect this situation and will write the following message in
the system log: "PCI-Express bandwidth available for this card is not
sufficient for optimal performance. For optimal performance a x8 PCI-Express
slot is required." If this error occurs, moving your adapter to a true x8 slot
will resolve the issue.

Link Loss on 10GbE Devices with Jumbo Frames enabled
----------------------------------------------------
You must not lower Receive_Buffers or Transmit_Buffers below 256 if jumbo
frames are enabled on an Intel(R) 10GbE Device. Doing so will cause loss of
link.

Failed connection and possible system instability
-------------------------------------------------
If you have non-Intel networking devices capable of Receive-Side Scaling
installed in your system, the Microsoft Windows registry keyword "RSSBaseCPU"
may have been changed from the default value of 0x0 to point to a logical
processor. If this keyword has been changed then devices based on Intel(R)
82598 or 82599 10 Gigabit Ethernet Controllers might not pass traffic.
Attempting to make driver changes in this state may cause system instability.
Set the value of RSSBaseCpu to 0x0, or to a value corresponding to a physical
processor, and reboot the system to resolve the issue.

1GbE Quad Port Server Adapter Notes
===================================

Hot Plug operations are not supported by the following Intel Quad Port Server
Adapters:

Intel(R) PRO/1000 PT Quad Port Server Adapter
Intel(R) PRO/1000 GT Quad Port Server Adapter
Intel(R) PRO/1000 MT Quad Port Server Adapter

System does not boot
--------------------
Your system may run out of I/O resources and fail to boot if you install more
than four quad port server adapters. Moving the adapters to different slots or
rebalancing resources in the system BIOS may resolve the issue.
This issue affects the following Adapters:
* Intel(R) Ethernet Server Adapter I350-T4
* Intel(R) Gigabit ET2 Quad Port Server Adapter
* Intel(R) Gigabit ET Quad Port Server Adapter
* Intel(R) Gigabit VT Quad Port Server Adapter
* Intel(R) PRO/1000 PF Quad Port Server Adapter

Intel PRO/1000 GT Quad Port Server Adapter Not recommended
for use on some systems
----------------------------------------------------------
The Intel PRO/1000 GT Quad Port Server Adapter does not function correctly in
the following systems:

* SuperMicro* P4DP6 running SCO Unixware or OpenServer 6
* Intel(R) Server Board SE7505VB2 based systems (PCI slot 5 only. Other slots
work as designed)

Code 10 on Intel(R) PRO/1000 PT Quad Port LP Server Adapter
-----------------------------------------------------------
You may encounter a Windows Code 10 error with an Intel(R) PRO/1000 PT Quad
Port LP Server Adapter installed in slot #4 of a SuperMicro 7046T-H6R system.
Moving the adapter to another slot will resolve the issue.

Intel PRO/1000 MT Quad Port Server Adapter Known Issues
-------------------------------------------------------
The Intel PRO/1000 MT Quad Port Server Adapter operates in 3.3 volt PCI-X slots
only. For best performance, this adapter should be installed in a 64-bit PCI-X
slot. Refer to the detailed installation instructions in the User's Guide for
additional requirements.

Wake on LAN is not supported on the Intel PRO/1000 MT Quad Port Server Adapter.
Trying to enable this feature with IBAUTIL.EXE will not have any effect.

The Intel PRO/1000 MT Quad Port Server Adapter supports Intel(R) Boot Agent
functionality on ports A and B, however it is disabled by default. To enable
and use the Intel Boot Agent, refer to the User's Guide and other information
in the \APPS\BOOTAGNT\ directory.

Multiple Intel PRO/1000 MT Quad Port Server Adapters in one system
------------------------------------------------------------------
Installing more than two Intel PRO/1000 MT Quad Port Server Adapters in the
same system is not recommended. Many systems are unable to support the power
requirements for more than two of these adapters.

Use only in a PCI-X Slot
------------------------
Reduced performance has been observed when the Intel PRO/1000 MT Quad Port
Server Adapter is installed in a slot other than a PCI-X slot.

Shared Interrupt Limitation
---------------------------
In some systems, the BIOS and OS assign the same interrupt number to two or
more different ports on the Intel PRO/1000 MT Quad Port Server Adapter. If this
occurs, these ports do not function properly. To address this issue, reassign
the system resources so that each port of the adapter has its own unique
interrupt number or disable one of the ports sharing the same interrupt number.

Downshifting
------------
When connecting to any Gigabit switch via a faulty CAT 5 cable where one pair
is broken, the adapter does not downshift from 1 Gig to 100Mbps. For the
adapter to downshift, it must identify two broken pairs in the cable.

Intel PRO/1000 MT Quad Port Server Adapter Not recommended
for use on some systems
----------------------------------------------------------
The Intel PRO/1000 MT Quad Port Server Adapter does not function correctly in
the following systems:

Dell* PowerEdge* 2500
Dell PowerEdge 6400
Dell PowerEdge 6450
Dell PowerEdge 6650SC
Intel Saber, Saber-R, and Saber-Rx Systems
SuperMicro 370DE6
SuperMicro P4DP6
IBM* eServer* xSeries* 365

Using the Intel PRO/1000 MT Quad Port Server Adapter in these configurations is
not recommended.

Heavy traffic may cause system reboot in some systems
-----------------------------------------------------
Using an Intel PRO/1000 MT Quad Port Server Adapter may cause a reboot in
systems with the Intel Profusion chipset including: Intel OCPRF100 and SRPM8
server systems; Compaq* ProLiant* 8000, 8500, ML750, DL760; Dell PowerEdge
8450, 6300, 6350; IBM* x370. Using the Intel PRO/1000 MT Quad Port Server
Adapter in these configurations is not recommended.

Intel(R) Ethernet Desktop Adapter and Network Connection Notes
==============================================================

The Intel(R) 82562V 10/100 Network Connection and Intel(R) 82562V 10/100
Network Connection are supported by the gigabit drivers.

Release 20.6 is the last release in which Intel(R) Ethernet iSCSI Boot supports
Intel(R) Ethernet Desktop Adapters and Network Connections. Starting with
Release 20.7, Intel Ethernet iSCSI Boot no longer supports Intel Ethernet
Desktop Adapters and Network Connections.

Known Issues
============

Log link state events do not display correctly in localized Windows Server 2016
-------------------------------------------------------------------------------
In a previous version of the driver, some log link state events did not display
correctly in some localized versions of Microsoft* Windows Server* 2016 when
bringing link down and then back up on Intel(R) i210AT adapters. This issue has
been corrected in the current driver version. Be sure to download and install
the latest drivers and software from Intel.

Unexpected CPU utilization
--------------------------
You may see one CPU reaching 90%-100% utilization if the RSS Load Balancing
Profile is set to NUMAScalingStatic. Setting the RSS Load Balancing Profile to
ClosestProcessor should correctly balance the CPU load. This issue affects
devices based on the Intel(R) Ethernet Controller X722 in systems running
Microsoft* Windows Server* 2019.

NVM update utilities exit with error on kernel 4.16 or higher
------------------------------------------------------------
On kernel 4.16 or higher, if you update the ixgbe, igb, or i40e driver and then
run any of the NVM update utilities (NVMUpdate, NVMCheck, QCU, or Bootutil),
the utility may exit with the error "The selected adapter cannot be updated due
to strict MMIO memory settings in the kernel." To fix this, set the iomem
kernel parameter to "relaxed" (i.e., iomem=relaxed) and reboot the system
before running the tool again. On kernel 4.16 or higher, the iomem parameter is
set to "strict" by default, which prevents the NVM update utilities from
accessing the MMIO of the device.

Device becomes unresponsive after Hardware diagnostics failure
--------------------------------------------------------------
If you have Data Center Bridging (DCB) enabled on your system, hardware
diagnostics may fail even if no hardware issue exists. This may cause the
device to stop responding. Reloading the driver will resolve this issue.
Disabling DCB and rerunning hardware diagnostics will display the correct
pass/fail results for the device.

Incorrect branding strings
--------------------------
Devices based on the Intel(R) Ethernet Controller X550 and Intel Ethernet
Controller X700 series may display incorrect branding strings in Windows Device
Manager. This issue does not affect the functionality of the device. This issue
only affects Microsoft* Windows Server* 2016.

Identify Adapter command does not blink LEDs as expected
--------------------------------------------------------
On some Intel(R) Ethernet Connections, the LEDs are connected to PHY and not to
the MAC. The driver's Identify Adapter functionality uses the MAC register, so
the LEDs will not blink on these devices. This affects the following devices:
*  Intel(R) Ethernet Connection X552 1000BASE-T
*  Intel(R) Ethernet Connection X552/X557-AT 10GBASE-T

Changing a VLAN ID to untagged and then reusing that VLAN ID may cause the
untagged VLAN to fail
--------------------------------------------------------------------------
On Windows 10 RS1, if you change a VLAN ID to untagged on a device or team and
then later reuse that VLAN ID on that device or team, the untagged VLAN may
fail to pass traffic. To resolve this issue, remove the untagged VLAN and
recreate it.

VXN Driver Fails To Load in Windows Server VM on ESX 6.5
--------------------------------------------------------
The VXN driver may fail to load with a yellow-bang error after installation on
a Windows Server 2016 or Windows Server 2012 R2 VM running on an ESX 6.5 host.
To fix this, reboot the VM.

Driver Installation Hangs
-------------------------
Driver installation for devices based on the Intel Ethernet X710 and XL710
controllers may hang. This may be because the device is connected to a switch
that is not advertising traffic class 0. To resolve the issue, disconnect the
device from the switch or configure the switch to advertise TC0, power cycle
your system, then restart the driver installation. This may occur with any
Intel Ethernet X710 or XL710 device on Microsoft Windows Server 2016.

Device Fails to Load
--------------------
Devices based on the Intel Ethernet X710, XL710, X722, and XXV710 controllers
may fail to load with a yellow-bang error. This may be because the device is
connected to a switch that is not advertising traffic class 0. To resolve the
issue, disconnect the device from the switch or configure the switch to
advertise TC0, and restart your system. This may occur with any Intel Ethernet
X710, XL710, X722, or XXV710 device on any version of Microsoft Windows Server.

Import of IntelNetCmdlets PowerShell Module Fails When Trailing
Backslash Used
----------------------------------------------------------------
If you include a trailing backslash ("\") at the end of the Import-Module
command, the import operation will fail (for example, "ps>import-module
c:\<path>\IntelNetCmdlets\"). In Microsoft Windows* 10 and Windows Server*
2016, the auto-complete function appends a trailing backslash. If you use
auto-complete when entering the Import-Module command, delete the trailing
backslash before pressing Return to execute the command.

Code 10 Error in Device Manager When Intel DCB Installed and RSS Queues
Changed to 16 or Greater
-----------------------------------------------------------------------
If the Intel DCB feature is installed, changing the number of Receive Side
Scaling (RSS) queues to 16 or greater may result in a Code 10 error in Device
Manager. To resolve this issue, reinstall the driver from the Intel
installation media. Note that this will reset the RSS queues value to the
default of 8. Do not change the RSS queues to 16 or greater, as doing so will
result in another Code 10 error. Setting RSS queues to a lower value such as 1,
2, or 4 does not cause error.

"Error getting the adapter info" message when opening device property sheet
---------------------------------------------------------------------------
Earlier versions of Windows Defender may mistake some Intel PROSet DLLs for
malware and delete these files. This causes an "Error getting the adapter info"
error. This issue affects Microsoft Windows* 7. Update Windows Defender to the
latest version and reinstall the Intel PROSet software to resolve the issue.

Driver Installation Issues on Microsoft* Windows* 10
----------------------------------------------------
Release 20.7 (or later) driver installs on Microsoft Windows 10 may time out or
fail due to extended wait time (up to 4 minutes per Ethernet port). In most
cases, despite the timeout, the driver installs correctly and is usable. If the
driver does not install correctly, retry the installation process. Note that
Intel(R) PROSet for Windows Device Manager relies on correctly installed
drivers.

Lower than expected throughput on X710/XL710 based devices
----------------------------------------------------------
If you have an X710 or XL710 based device installed in a four CPU socket
system. Receive and transmit traffic may be significantly lower than expected.
Setting your interrupt rate to High may mitigate the issue.

Link loss after identifying the adapter
---------------------------------------
All ports on the device may lose link when you run the diagnostic tests to
identify the adapter on a single port. Link will return to normal after several
seconds. This only affects 10G-BaseT devices based on the Intel(R) Ethernet
Controller X710.

System does not get link when connected to a 10GbE switch
---------------------------------------------------------
Systems that contain an Intel(R) i210 or i211 device may not link to a 10GbE
switch. This may happen when the system's Ethernet cable is not connected to
the switch during power up or if the cable is disconnected for more than a
couple of minutes. Disabling and enabling the device in the operating system
will restore link.

iSCSI traffic stops after disabling RSC
---------------------------------------
To prevent a lost connection, Receive Segment Coalescing (RSC) must be disabled
prior to configuring a VLAN bound to a port that will be used for connecting to
an iSCSI target. Workaround this issue by disabling Receive Segment Coalescing
before setting up the VLAN. This will avoid this traffic stop.

Multicast routing table is not automatically set up
---------------------------------------------------
The multicast routing table for the Intel(R) Ethernet Virtual Function 700
Series driver is not automatically set up and the virtual machine will not
receive multicast traffic. Manually adding the multicast routing will resolve
the issue.

Enable PME setting not set to expected value
--------------------------------------------
After running Sysprep, the Enable PME setting may not be set to the expected
value. You should manually verify and configure the setting.

Receive Side Scaling value is blank
-----------------------------------
Changing the Receive Side Scaling setting of an adapter in a team may cause the
value for that setting to appear blank when you next check it. It may also
appear blank for the other adapters in the team. The adapter may be unbound
from the team in this situation. Disabling and enabling the team will resolve
the issue.

CPU utilization higher than expected
------------------------------------
Setting RSS Queues to a value greater than 4 is only advisable for large web
servers with several processors. Values greater than 4 may increase CPU
utilization to unacceptable levels and have other negative impacts on system
performance.

RSS Load Balancing Profile Advanced Setting
-------------------------------------------
Setting the "RSS load balancing profile" Advanced Setting to "ClosestProcessor"
may significantly reduce CPU utilization. However, in some system
configurations (such as a system with more Ethernet ports than processor
cores), the "ClosestProcessor" setting may cause transmit and receive failures.
Changing the setting to "NUMAScalingStatic" will resolve the issue.

Unexpected link loss when connected to Netgear XSM7224S switch
--------------------------------------------------------------
The Netgear XSM7224s switch is sensitive to Energy Efficient Ethernet (EEE)
mode. Link flap errors will occur with several Intel devices when EEE mode is
enabled. Disable EEE mode to resolve the issue. This issue affects devices
based on the following:
* Intel(R) I350 controller
* Intel(R) 82579 series of controllers
* Intel(R) I217 series of controllers
* Intel(R) I218 series of controllers

Reboot Prompt Appears when modifying the Performance Profile
------------------------------------------------------------
In Microsoft* Windows Server*, after modifying the performance profile, a
reboot prompt may appear. The Intel(R) Ethernet FCoE boot was configured and
there is no need to reboot. The base driver reloads are blocked if FCoE boot is
configured and the system is connected to an FCoE target, even if the system
was booted locally.

Opening Windows Device Manager property sheet takes longer than expected
------------------------------------------------------------------------
The Windows Device Manager property sheet may take 60 seconds or longer to
open. The driver must discover all Intel Ethernet devices and initialize them
before it can open the property sheet. This data is cached, so subsequent
openings of the property sheet are generally quicker.

Audio or video distortion when LAN cable is connected or disconnected
---------------------------------------------------------------------
Momentary audio distortion or video playback issues may occur when you connect
or disconnect a LAN cable to the onboard Ethernet port. Intel(R) 82577 and
82578 based network connections are affected by this issue.

Reduced or erratic receive performance
--------------------------------------
Intel(R) 7500 chipset-based systems may experience degraded receive
performance. Increasing receive descriptors to 1024 will resolve the issue.
Disabling C-states in the system BIOS will also resolve the issue.

Activity LED blinks unexpectedly
--------------------------------
If a system based on the 82577, 82578, or 82579 controller is connected to a
hub, the Activity LED will blink for all network traffic present on the hub.
Connecting the system to a switch or router will filter out most traffic not
addressed to the local port.

Unexpected NMI with 82599-based NICs
------------------------------------
If you set the PCIe Maximum Payload Size to 256 bytes in your system BIOS and
install an 82599-based NIC, you may receive an NMI when the NIC attains link.
This happens when the physical slot does not support a payload size of 256
Bytes even if the BIOS does. Moving the adapter to a slot that supports 256
bytes will resolve the issue. Consult your system documentation for information
on supported payload values.

VLANs are not supported on VMQ enabled adapters and teams
---------------------------------------------------------
If you create a VLAN on a VMQ enabled adapter, the VMQ setting will
automatically be set to disabled. The same will happen if you create a VLAN on
a team whose member adapters have VMQ enabled.

Unexpected Connectivity Loss
----------------------------
If you uncheck the "Allow the computer to turn off this device to save power"
box on the Power Management tab and then put you system to sleep, you may lose
connectivity when you exit sleep. You must disable and enable the NIC to
resolve the issue. Installing Intel(R)PROSet for Windows Device Manager will
also resolve the issue.

Device Manager freezes on VLAN removal
--------------------------------------
Removing multiple VLANs from the Intel(R) 82576 Virtual Function device may
cause Device Manager to freeze. You must reboot the virtual partition to
resolve the issue.

SNMP errors in the System Event Log
-----------------------------------
Under Microsoft Windows 7 or Windows Server 2008 R2, you may see the following
error in the System Event Log: "The SNMP Service encountered an error while
accessing the registry key
"SYSTEM\CurrentControlSet\Servcies\SNMP\Parameters\TrapConfiguration"
The Windows 7 SNMP service start up isn't properly configuring the service with
a TrapConfiguration key. Perform the following to correct the issue:
1. Open Services applet (run services.msc).
2. Right click on SNMP Service, then select Properties.
3. Click on the Traps tab. Enter "public" for the Community name and click Add
to list.
4. Click on the Security tab. Click the Add button. Enter "public" and click on
the Add button.

System hang at login or shut down
---------------------------------
On the systems listed below, installing Intel(R) Gigabit Quad Port Server
Adapters may hang the system at the login screen or when shutting down. This
has been reported on:
* Intel(R) PRO/1000 PT Quad Port LP Server Adapter
* Intel(R) Gigabit ET Quad Port Server Adapter
And systems with the following motherboards:
* Intel(R) Server Board S5400SF
* Intel(R) Server Board S5000VSA
* Intel(R) Server Board S5000PAL
* Intel(R) Server Board S5000XAL
* Intel(R) Workstation Board S5000XVN
Installing system BIOS 97 or later will resolve this issue.

VLANs unsupported on some Intel devices
---------------------------------------
The following devices do not support VLANs:
- Intel(R) 82567V-2 Gigabit Network Connection
- Intel(R) 82567V Gigabit Network Connection

Direct Assignment in a Virtual Environment
------------------------------------------
The following Intel devices do not support Direct Assignment:
- All PCI devices
- All PCI-X devices
- Older PCIe devices

Reduced Large Send Offload performance
--------------------------------------
Large Send Offload (LSO) and IPSec Offload are not compatible. LSO is
automatically disabled when IPSec Offload is enabled. This may reduce the
performance of non-IPSec traffic. Confining all of your IPSec traffic to one
port and enabling IPSec Offload only on that port may mitigate this issue. On
Microsoft Windows 8.1 and Server 2012 and later, devices based on the 82576,
82599, and X540 controllers are not affected by this issue.

Hot Plug does not function in Microsoft Windows
-----------------------------------------------
On an Intel(R) Server System SR9000MK4U, the following dual port server
adapters cannot be removed using the system's Hot Plug functionality. Use the
Windows Safely Remove Hardware utility to remove the adapters.
- Intel(R) PRO/1000 PT Dual Port Server Adapter
- Intel(R) 10 Gigabit XF SR Dual Port Server Adapter
Hot Add operations may fail on Intel(R) Gigabit ET Dual Port Server Adapters.
Doing so may cause a code 12 error. Hot Replace operations function normally.

Dropped Receive Packets on Half-duplex 10/100 Networks
------------------------------------------------------
If you have an Intel PCI Express adapter installed, running at 10 or 100 Mbps,
half-duplex, with TCP Segment Offload (TSO) enabled, you may observe occasional
dropped receive packets. To work around this problem, disable TSO, or update
the network to operate in full-duplex and/or 1 Gbps.

Lost SOL and IDER sessions
--------------------------
SOL and IDER sessions may be lost if spanning tree is enabled. Turn off
spanning tree protocol on switch ports connected to devices configured for SOL
and IDER access.

Procedure for installing and upgrading drivers and utilities
------------------------------------------------------------
Intel does not recommend installing or upgrading drivers and Intel(R) PROSet
software over a network connection. Instead, install or upgrade drivers and
utilities from each system. To install or upgrade drivers and utilities, follow
the instructions in the User Guide.

Installing Intel PROSet and Intel PROSet for Windows Device Manager on
the same system
----------------------------------------------------------------------
The Intel PROSet install process prevents installing both Intel PROSet and
Intel PROSet for Windows Device Manager on the same system. When you install
Intel PROSet for Windows Device Manager, prior versions of PROSet are
uninstalled automatically.

"Malicious script detected" warning from Norton AntiVirus* during
PROSet Uninstall
-----------------------------------------------------------------
The Intel PROSet uninstall process uses a Visual Basic script as part of the
process. Norton AntiVirus and other virus scanning software may mistakenly flag
this as a malicious or dangerous script. Letting the script run allows the
uninstall process to complete normally.

"Out Of Disk Space" Message during Installation
-----------------------------------------------
The boot partition requires a minimum of 15 MB free space in order to install
Intel PROSet, regardless of which drive you specify for installation. If there
is insufficient space on the partition you will see this error message, and the
product will not install.

Windows Code 10 Error Message on Driver Install or Upgrade
----------------------------------------------------------
If you encounter a Windows Code 10 error message when installing or upgrading
drivers, reboot to resolve the issue.

Throughput reduction after Hot-Replace
--------------------------------------
If an Intel gigabit adapter is under extreme stress and is hot-swapped,
throughput may significantly drop. This may be due to the PCI property
configuration by the Hot-Plug software. If this occurs, throughput can be
restored by restarting the system.

No settings available on the Intel(R) Boot Options tab in Windows Device
Manager after flashing an EFI image
------------------------------------------------------------------------
The settings have been hidden because the EFI environment does not make use of
them.

Red Screen with 5400 general exception error after
lanutil64 -blink -all command
--------------------------------------------------
Using the EFI lanutil64 utility to blink the identification LEDs on all network
connections on systems that contain Intel PRO/100 devices may cause the system
to crash with a 5400 general exception error. Using the utility to blink the
identification LED on an individual network connection will not cause the
system to crash.

Link Difficulties With 82541 or 82547 Based Connections
-------------------------------------------------------
The PROSet Advanced tab now contains a setting allowing the master/slave mode
to be forced. This improves time-to-link with some unmanaged switches. For
older adapters and controllers, you may encounter difficulty with 82541 or
82547 based connections.

Intel Gigabit Network Adapters (copper only) do not detect active
link during load time
-----------------------------------------------------------------
Some Intel Gigabit Network adapters, especially copper adapters, cannot
detect an active link during load time. To resolve this issue, try
the following workarounds.
- Re-attach to the server without reloading the driver.
- For DOS-based installations, add a delay of 4 to 5 seconds in the batch file
after the load driver command.
- Load the configuration by manually entering commands.
- Set adapter to link at 1000 Mbps only.

Network stack will not enable RSC
-------------------------------------------------------
If Intel Data Center Bridging (DCB) is installed (FCoE, iSCSi, or both), the
network stack will not enable Receive Segment Coalescing (RSC).

PXE option ROM does not follow the PXE specification with respect to the
final "discover" cycle
------------------------------------------------------------------------
In order to avoid long wait periods, the option ROM no longer includes the
final 32-second discover cycle. (If there was no response in the prior
16-second cycle, it is almost certain that there will be none in the final,
32-second cycle.
