Virtio-net driver currently programs MAC address byte by byte,
this means that we have an intermediate step where mac is wrong.
This patch introduced a new control command to set MAC address
in one time, and added a new feature flag VIRTIO_NET_F_MAC_ADDR
for this feature.

"mac" field will be set to read-only when VIRTIO_NET_F_CTRL_MAC_ADDR
 is acked.

Thanks, applied.

Cheers,
Rusty.
