+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:
+
+http://www.redhat.com/promo/summit/2008/downloads/pdf/Thursday/Mark_Wagner.pdf
+
+
+Known Issues
+============
+
+
+Support
+=======
+
+For general information, go to the Intel support website at:
+
+ http://support.intel.com
+
+or the Intel Wired Networking project hosted by Sourceforge at:
+
+ http://e1000.sourceforge.net
+
+If an issue is identified with the released source code on the supported
+kernel with a supported adapter, email the specific information related
+to the issue to e1000-devel@lists.sourceforge.net and copy
+net...@vger.kernel.org.
