virtio-net: introduce a new macaddr control
In virtio-net guest driver, currently we write MAC address to
pci config space 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, it's atomic.
VIRTIO_NET_F_CTRL_MAC_ADDR is a new feature bit for compatibility.
"mac" field will be set to read-only when VIRTIO_NET_F_CTRL_MAC_ADDR
is acked.
