[Qemu-devel] [PULL 1/1] smc91c111: Fix receive starvation

[Stefan Hajnoczi]

From: Sebastian Huber <sebastian.huber@embedded-brains.de>

In case the smc91c111 interface signals that it cannot receive more
packets the packets are queued and further reception will be disabled.
In case the interface is again ready to receive packets notify the upper
layer.
