i40e: include i40e in kernel proper
This patch adds the changes for Kconfig, i40e.txt, MAINTAINERS, Kbuild and new i40e/Makefile to build i40e with the kernel. New driver build option is CONFIG_I40E Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Shannon Nelson <shannon.nelson@intel.com> CC: PJ Waskiewicz <peter.p.waskiewicz.jr@intel.com> CC: e1000-devel@lists.sourceforge.net Tested-by: Kavindya Deegala <kavindya.s.deegala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

Linux Base Driver for the Intel(R) Ethernet Controller XL710 Family

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 &
|
||||
Driver ID Guide at:
|
||||
|
||||
http://support.intel.com/support/network/sb/CS-012904.htm
|
||||
|
||||
|
||||
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
|
||||
----
|
||||
Fiber Channel over Ethernet (FCoE) hardware offload is not currently
|
||||
supported.
|
||||
|
||||
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.
|
||||
|
||||
|
||||
Performance Tuning
|
||||
==================
|
||||
|
||||
An excellent article on performance tuning can be found at:
