+Identifying the Adapter
+=======================
+
+To find if one or more Pensando PCI Ethernet devices are installed on the
+host, check for the PCI devices::
+
+ $ lspci -d 1dd8:
+ b5:00.0 Ethernet controller: Device 1dd8:1002
+ b6:00.0 Ethernet controller: Device 1dd8:1002
+
+If such devices are listed as above, then the ionic.ko driver should find
+and configure them for use. There should be log entries in the kernel
+messages such as these::
+
+ $ dmesg | grep ionic
+ ionic Pensando Ethernet NIC Driver, ver 0.11.0-k
+ ionic 0000:b5:00.0 enp181s0: renamed from eth0
+ ionic 0000:b5:00.0: NETDEV_CHANGENAME lif0 enp181s0
+ ionic 0000:b6:00.0 enp182s0: renamed from eth0
+ ionic 0000:b6:00.0: NETDEV_CHANGENAME lif0 enp182s0
+
+Special Features
+================
+
+Extended Debug Statistics
+-------------------------
+Basic network driver statistics are available through ethtool's
+statistics request::
+
+ $ ethtool -S enp181s0
+
+Extended debugging statistics can be enabled with the driver private
+flag "sw-dbg-stats"::
+
+ $ ethtool --show-priv-flags enp181s0
+ Private flags for enp181s0:
+ sw-dbg-stats: off
+ $ ethtool --set-priv-flags enp181s0 sw-dbg-stats on
+
+Support
+=======
+For general Linux networking support, please use the netdev mailing
+list, which is monitored by Pensando personnel::
+ netdev@vger.kernel.org
+
+For more specific support needs, please use the Pensando driver support
+email::
+ drivers@pensando.io

This patch adds a basic driver framework for the Pensando IONIC network device. There is no functionality right now other than the ability to load and unload.
