Identifying Your Adapter
|
|
|
|
|
========================
|
|
|
|
|
|
|
|
|
|
The driver in this release is compatible with the Intel Ethernet
|
|
|
|
|
Controller XL710 Family.
|
|
|
|
|
|
|
|
|
|
For more information on how to identify your adapter, go to the Adapter &

Enabling the driver
|
|
|
|
|
===================
|
|
|
|
|
|
|
|
|
|
The driver is enabled via the standard kernel configuration system,
|
|
|
|
|
using the make command:
|
|
|
|
|
|
|
|
|
|
Make oldconfig/silentoldconfig/menuconfig/etc.
|
|
|
|
|
|
|
|
|
|
The driver is located in the menu structure at:
|
|
|
|
|
|
|
|
|
|
-> Device Drivers
|
|
|
|
|
-> Network device support (NETDEVICES [=y])
|
|
|
|
|
-> Ethernet driver support
|
|
|
|
|
-> Intel devices
|
|
|
|
|
-> Intel(R) Ethernet Controller XL710 Family
|
|
|
|
|
|
|
|
|
|
Additional Configurations
|
|
|
|
|
=========================
|
|
|
|
|
|
|
|
|
|
Generic Receive Offload (GRO)
|
|
|
|
|
-----------------------------
|
|
|
|
|
The driver supports the in-kernel software implementation of GRO. GRO has
|
|
|
|
|
shown that by coalescing Rx traffic into larger chunks of data, CPU
|
|
|
|
|
utilization can be significantly reduced when under large Rx load. GRO is
|
|
|
|
|
an evolution of the previously-used LRO interface. GRO is able to coalesce
|
|
|
|
|
other protocols besides TCP. It's also safe to use with configurations that
|
|
|
|
|
are problematic for LRO, namely bridging and iSCSI.
|
|
|
|
|
|
|
|
|
|
Ethtool
|
|
|
|
|
-------
|
|
|
|
|
The driver utilizes the ethtool interface for driver configuration and
|
|
|
|
|
diagnostics, as well as displaying statistical information. The latest
|
|
|
|
|
ethtool version is required for this functionality.
|
|
|
|
|
|
|
|
|
|
The latest release of ethtool can be found from
|
|
|
|
|
https://www.kernel.org/pub/software/network/ethtool
|
|
|
|
|
|
|
|
|
|
Data Center Bridging (DCB)
|
|
|
|
|
--------------------------
|
|
|
|
|
DCB configuration is not currently supported.
|
|
|
|
|
|
|
|
|
|
FCoE
|
|
|
|
|
----
|
2014-08-02 04:27:04 +08:00
|
|
|
The driver supports Fiber Channel over Ethernet (FCoE) and Data Center
|
|
|
|
|
Bridging (DCB) functionality. Configuring DCB and FCoE is outside the scope
|
|
|
|
|
of this driver doc. Refer to http://www.open-fcoe.org/ for FCoE project
|
|
|
|
|
information and http://www.open-lldp.org/ or email list
|
|
|
|
|
e1000-eedc@lists.sourceforge.net for DCB information.

|
|
|
|
|
|
|
|
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.
