+  2016-07-11:  Received hardware today and the board came up on the very
+    first try.  That does not happen often.  At this point, the very basic
+    NSH configuration is working and LEDs are working.  The only odd
+    behavior that I see is that pressing SW3 causes an unexpected interrupt
+    error.
+  2016-07-12:  Added support for the KSZ8081 PHY and added the netnsh
+    configuration.  Untested as of this writing.
