Linux* Base Driver for Intel(R) Ethernet Network Connection
|
||||
===========================================================
|
||||
|
||||
Intel Gigabit Linux driver.
|
||||

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 is not supported and 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. The latest
|
||||
version of ethtool can be found at:
|
||||
|
||||
http://ftp.kernel.org/pub/software/network/ethtool/
|
||||
|
||||
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.
|
||||
|
||||
MAC and VLAN anti-spoofing feature
|
||||
----------------------------------
|
||||
When a malicious driver attempts to send a spoofed packet, it is dropped by
|
||||
the hardware and not transmitted. An interrupt is sent to the PF driver
|
||||
notifying it of the spoof attempt.
|
||||
|
||||
When a spoofed packet is detected the PF driver will send the following
|
||||
message to the system log (displayed by the "dmesg" command):
|
||||
|
||||
Spoof event(s) detected on VF(n)
|
||||
|
||||
Where n=the VF that attempted to do the spoofing.
|
||||
|
||||
Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool
|
||||
------------------------------------------------------------
|
||||
You can set a MAC address of a Virtual Function (VF), a default VLAN and the
|
||||
rate limit using the IProute2 tool. Download the latest version of the
|
||||
iproute2 tool from Sourceforge if your version does not have all the
|
||||
features you require.
