From: Peter Lieven <[email protected]> commit fefe2a78 accidently dropped the code path for injecting raw packets. This feature is needed for sending gratuitous ARPs after an incoming migration has completed. The result is increased network downtime for vservers where the network card is not virtio-net with the VIRTIO_NET_F_GUEST_ANNOUNCE feature.
