This file describes the Linux* Base Driver for the Intel(R) PRO/10GbE Family
of Adapters, version 1.0.x.
This file describes the ixgb Linux Base Driver for the 10 Gigabit Intel(R)
Network Connection. This driver includes support for Itanium(R)2-based
systems.
For questions related to hardware requirements, refer to the documentation
supplied with your Intel PRO/10GbE adapter. All hardware requirements listed
apply to use with Linux.
supplied with your 10 Gigabit adapter. All hardware requirements listed apply
to use with Linux.
The following features are available in this kernel:
- Native VLANs
- Channel Bonding (teaming)
- SNMP
Channel Bonding documentation can be found in the Linux kernel source:
/Documentation/networking/bonding.txt
The driver information previously displayed in the /proc filesystem is not
supported in this release. Alternatively, you can use ethtool (version 1.6
or later), lspci, and ifconfig to obtain the same information.
Instructions on updating ethtool can be found in the section "Additional
Configurations" later in this document.
Identifying Your Adapter
========================
To verify your Intel adapter is supported, find the board ID number on the
adapter. Look for a label that has a barcode and a number in the format
A12345-001.
The following Intel network adapters are compatible with the drivers in this
release:

1. make modules && make modules_install
2. Load the module:
    modprobe ixgb <parameter>=<value>
The insmod command can be used if the full
path to the driver module is specified. For example:
insmod /lib/modules/<KERNEL VERSION>/kernel/drivers/net/ixgb/ixgb.ko
With 2.6 based kernels also make sure that older ixgb drivers are
removed from the kernel, before loading the new module:
rmmod ixgb; modprobe ixgb
3. Assign an IP address to the interface by entering the following, where
x is the interface number:
ifconfig ethx <IP_address>
4. Verify that the interface works. Enter the following, where <IP_address>
is the IP address for another machine on the same subnet as the interface
that is being tested:
ping <IP_address>

Improving Performance

With the Intel PRO/10 GbE adapter, the default Linux configuration will very
likely limit the total available throughput artificially. There is a set of
things that when applied together increase the ability of Linux to transmit
and receive data. The following enhancements were originally acquired from
settings published at http://www.spec.org/web99 for various submitted results

Resolving Slow UDP Traffic

can receive TCP traffic, it could be because Linux, by default, does not set
the network stack buffers as large as they need to be to support high UDP

can be increased significantly more if necessary for your application.
Additional Configurations
=========================
Configuring the Driver on Different Distributions
-------------------------------------------------
Configuring a network driver to load properly when the system is started is
distribution dependent. Typically, the configuration process involves adding
an alias line to /etc/modprobe.conf as well as editing other system startup
scripts and/or configuration files. Many popular Linux distributions ship
with tools to make these changes for you. To learn the proper way to
configure a network device for your system, refer to your distribution
documentation. If during this process you are asked for the driver or module
name, the name for the Linux Base Driver for the Intel 10GbE Family of
Adapters is ixgb.
Viewing Link Messages
---------------------
Link messages will not be displayed to the console if the distribution is
restricting system messages. In order to see network driver link messages on
your console, set dmesg to eight by entering the following:
dmesg -n 8
NOTE: This setting is not saved across reboots.
Jumbo Frames
------------
The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
enabled by changing the MTU to a value larger than the default of 1500.
The maximum value for the MTU is 16114. Use the ifconfig command to
increase the MTU size. For example:
ifconfig ethx mtu 9000 up
The maximum MTU setting for Jumbo Frames is 16114. This value coincides
with the maximum Jumbo Frames size of 16128.
Ethtool
-------
The driver utilizes the ethtool interface for driver configuration and
diagnostics, as well as displaying statistical information. Ethtool
version 1.6 or later is required for this functionality.
The latest release of ethtool can be found from
http://sourceforge.net/projects/gkernel
NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support
for a more complete ethtool feature set can be enabled by upgrading
to the latest version.
NAPI
----
NAPI (Rx polling mode) is supported in the ixgb driver. NAPI is enabled
or disabled based on the configuration of the kernel. see CONFIG_IXGB_NAPI
See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
Known Issues/Troubleshooting
============================
NOTE: After installing the driver, if your Intel Network Connection is not
working, verify in the "In This Release" section of the readme that you have
installed the correct driver.
Intel(R) PRO/10GbE CX4 Server Adapter Cable Interoperability Issue with
Fujitsu XENPAK Module in SmartBits Chassis
---------------------------------------------------------------------
Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
Server adapter or the SmartBits. If this situation occurs using a different
cable assembly may resolve the issue.
CX4 Server Adapter Cable Interoperability Issues with HP Procurve 3400cl
Switch Port
------------------------------------------------------------------------
Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
adapter is connected to an HP Procurve 3400cl switch port using short cables
(1 m or shorter). If this situation occurs, using a longer cable may resolve
the issue.
Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
errors may be received either by the CX4 Server adapter or at the switch. If
this situation occurs, using a different cable assembly may resolve the issue.
Jumbo Frames System Requirement
-------------------------------
Memory allocation failures have been observed on Linux systems with 64 MB
of RAM or less that are running Jumbo Frames. If you are using Jumbo
Frames, your system may require more than the advertised minimum
requirement of 64 MB of system memory.
Performance Degradation with Jumbo Frames
-----------------------------------------
Degradation in throughput performance may be observed in some Jumbo frames
environments. If this is observed, increasing the application's socket buffer
size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
See the specific application manual and /usr/src/linux*/Documentation/
networking/ip-sysctl.txt for more details.
Allocating Rx Buffers when Using Jumbo Frames
---------------------------------------------
Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
the available memory is heavily fragmented. This issue may be seen with PCI-X
adapters or with packet split disabled. This can be reduced or eliminated
by changing the amount of available memory for receive buffer allocation, by
increasing /proc/sys/vm/min_free_kbytes.
Multiple Interfaces on Same Ethernet Broadcast Network
------------------------------------------------------
Due to the default ARP behavior on Linux, it is not possible to have
one system on two IP networks in the same Ethernet broadcast domain
(non-partitioned switch) behave as expected. All Ethernet interfaces
will respond to IP traffic for any IP address assigned to the system.
This results in unbalanced receive traffic.
If you have multiple interfaces in a server, do either of the following:
- Turn on ARP filtering by entering:
echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
- Install the interfaces in separate broadcast domains - either in
different switches or in a switch partitioned to VLANs.
UDP Stress Test Dropped Packet Issue
--------------------------------------
Under small packets UDP stress test with 10GbE driver, the Linux system
may drop UDP packets due to the fullness of socket buffers. You may want
to change the driver's Flow Control variables to the minimum value for
controlling packet reception.
Tx Hangs Possible Under Stress
------------------------------
Under stress conditions, if TX hangs occur, turning off TSO
"ethtool -K eth0 tso off" may resolve the problem.
