[Qemu-devel] [PULL 5/6] sunhme: fix return values from sunhme_receive() during receive packet processing

[Mark Cave-Ayland]

The current return values in sunhme_receive() when processing incoming packets
are inverted from what they should be. Make sure that we return 0 to indicate
the packet was discarded (and polling is to be disabled) and -1 to indicate
that the packet was discarded but polling for incoming data is to be continued.
