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

+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

+kernel with a supported adapter, email the specific information related
+to the issue to e1000-devel@lists.sourceforge.net and copy
