Linux* Base Driver for Intel(R) Network Connection
==================================================
Intel Gigabit Linux driver.
Copyright(c) 1999 - 2010 Intel Corporation.
Contents
========
- Identifying Your Adapter
- Additional Configurations
- Support
Identifying Your Adapter
========================
This driver supports all 82575, 82576 and 82580-based Intel (R) gigabit network
connections.
For specific information on how to identify your adapter, go to the Adapter &
Driver ID Guide at:
http://support.intel.com/support/go/network/adapter/idguide.htm
Command Line Parameters
=======================
The default value for each parameter is generally the recommended setting,
unless otherwise noted.
max_vfs
-------
Valid Range: 0-7
Default Value: 0
This parameter adds support for SR-IOV. It causes the driver to spawn up to
max_vfs worth of virtual function.
Additional Configurations
=========================
Jumbo Frames
------------
Jumbo Frames support is enabled by changing the MTU to a value larger than
the default of 1500. Use the ifconfig command to increase the MTU size.
For example:
ifconfig eth<x> mtu 9000 up
This setting is not saved across reboots.
Notes:
- The maximum MTU setting for Jumbo Frames is 9216. This value coincides
with the maximum Jumbo Frames size of 9234 bytes.
- Using Jumbo Frames at 10 or 100 Mbps may result in poor performance or
loss of link.
Ethtool
-------
The driver utilizes the ethtool interface for driver configuration and
diagnostics, as well as displaying statistical information.
http://sourceforge.net/projects/gkernel.
Enabling Wake on LAN* (WoL)
---------------------------
WoL is configured through the Ethtool* utility.
For instructions on enabling WoL with Ethtool, refer to the Ethtool man page.
WoL will be enabled on the system during the next shut down or reboot.
For this driver version, in order to enable WoL, the igb driver must be
loaded when shutting down or rebooting the system.
Wake On LAN is only supported on port A of multi-port adapters.
Wake On LAN is not supported for the Intel(R) Gigabit VT Quad Port Server
Adapter.
Multiqueue
----------
In this mode, a separate MSI-X vector is allocated for each queue and one
for "other" interrupts such as link status change and errors. All
interrupts are throttled via interrupt moderation. Interrupt moderation
must be used to avoid interrupt storms while the driver is processing one
interrupt. The moderation value should be at least as large as the expected
time for the driver to process an interrupt. Multiqueue is off by default.
REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not
found, the system will fallback to MSI or to Legacy interrupts.
LRO
---
Large Receive Offload (LRO) is a technique for increasing inbound throughput
of high-bandwidth network connections by reducing CPU overhead. It works by
aggregating multiple incoming packets from a single stream into a larger
buffer before they are passed higher up the networking stack, thus reducing
the number of packets that have to be processed. LRO combines multiple
Ethernet frames into a single receive in the stack, thereby potentially
decreasing CPU utilization for receives.
NOTE: You need to have inet_lro enabled via either the CONFIG_INET_LRO or
CONFIG_INET_LRO_MODULE kernel config option. Additionally, if
CONFIG_INET_LRO_MODULE is used, the inet_lro module needs to be loaded
before the igb driver.
You can verify that the driver is using LRO by looking at these counters in
Ethtool:
lro_aggregated - count of total packets that were combined
lro_flushed - counts the number of packets flushed out of LRO
lro_no_desc - counts the number of times an LRO descriptor was not available
for the LRO packet
NOTE: IPv6 and UDP are not supported by LRO.
Support

kernel with a supported adapter, email the specific information related

Linux* Base Driver for Intel(R) Network Connection
==================================================
Intel Gigabit Linux driver.
Copyright(c) 1999 - 2010 Intel Corporation.
Contents
========
- Identifying Your Adapter
- Additional Configurations
- Support
This file describes the igbvf Linux* Base Driver for Intel Network Connection.
The igbvf driver supports 82576-based virtual function devices that can only
be activated on kernels that support SR-IOV. SR-IOV requires the correct
platform and OS support.
The igbvf driver requires the igb driver, version 2.0 or later. The igbvf
driver supports virtual functions generated by the igb driver with a max_vfs
value of 1 or greater. For more information on the max_vfs parameter refer
to the README included with the igb driver.
The guest OS loading the igbvf driver must support MSI-X interrupts.
This driver is only supported as a loadable module at this time. Intel is
not supplying patches against the kernel source to allow for static linking
of the driver. For questions related to hardware requirements, refer to the
documentation supplied with your Intel Gigabit adapter. All hardware
requirements listed apply to use with Linux.
Instructions on updating ethtool can be found in the section "Additional
Configurations" later in this document.
VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs.
Identifying Your Adapter
========================
The igbvf driver supports 82576-based virtual function devices that can only
be activated on kernels that support SR-IOV.
For more information on how to identify your adapter, go to the Adapter &
Driver ID Guide at:
http://support.intel.com/support/go/network/adapter/idguide.htm
For the latest Intel network drivers for Linux, refer to the following
website. In the search field, enter your adapter name or type, or use the
networking link on the left to search for your adapter:
