[Intel-wired-lan] [PATCH net-next 19/19] idpf: introduce idpf driver

[Alan Brady <alan.brady@intel.com>]

This adds the idpf driver which uses the iecm module to provide common
functionality. Device specific behavior and registers are defined here and
handed off to iecm which takes over the rest of the flow.

+
+Contents
+========
+
+- Enabling the driver
+- Support
+
+The driver in this release supports Intel's Smart Network Adapter Family Series
+of products. For more information, visit Intel's support page at
+https://support.intel.com.
+
+Enabling the driver
+===================
+The driver is enabled via the standard kernel configuration system,
+using the make command::
+
+  make oldconfig/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) Smart Network Adapter Family Series Support
+
+Support
+=======
+For general information, go to the Intel support website at:
+
+https://www.intel.com/support/
+
+or the Intel Wired Networking project hosted by Sourceforge at:
+
+https://sourceforge.net/projects/e1000
+
+If an issue is identified with the released source code on a supported kernel
+with a supported adapter, email the specific information related to the issue
+to e1000-devel at lists.sf.net.
