From 491a1f494ed4c0d1a8593dd04b645f8e63c4cfae Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Fri, 26 Jun 2015 15:27:16 +1000 Subject: hw/net: fix mcf_fec driver receiver The network mcf_fec driver emulated receive side method is returning a result of 0 causing the network layer to disable receive for this emulated device. This results in the guest only ever receiving one packet. Fix the recieve side processing to return the number of bytes that we passed back through to the guest.
