[Qemu-devel] [PATCH] virtio-net: Drop net_virtio_info.can_receive

[Fam Zheng]

virtio_net_receive still does the check by calling
virtio_net_can_receive, if the device or driver is not ready, the packet
is dropped.

This is necessary because returning false from can_receive complicates
things: the peer would disable sending until we explicitly flush the
queue.
