H A Dcadence_gem.c3ae5725f86a82751cccf6bc075e5ebfb327ac283 Wed Dec 04 06:01:28 UTC 2013 Peter Crosthwaite <peter.crosthwaite@xilinx.com> net/cadence_gem: Improve can_receive debug printfery

Currently this just floods indicating that can_receive has been called
by the net framework. Instead, save the result of the most recent
can_receive callback as state and only print a message if the result
changes (indicating some sort of actual state change in GEM). Make said
debug message more meaningful as well.
