|
=========================================================== |
|
|
|

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. |
