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. Signed-off-by: Amos Kong <akong@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
