Currently virtio-net code relys on the layout of descriptor, this patchset removed the assumptions and introduced a control command to set mac address. Last patch is a trivial renaming. V2: check guest's iov_len V3: fix of migration compatibility make mac field in config space read-only when new feature is acked V4: add fix of descriptor layout assumptions, trivial rename V5: fix
