+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 0.15.0-k
+ ionic 0000:b5:00.0 enp181s0: renamed from eth0
+ ionic 0000:b6:00.0 enp182s0: renamed from eth0
+
+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::
