When live migration is finished, the backup VM needs to proactively announce
its new location. DPDK vhost has implemented VHOST_USER_PROTOCOL_F_RARP to
generate a RARP packet to switch in dequeue path. Another method is to let
the guest proactively send out RARP packet using VIRTIO_NET_F_GUEST_ANNOUNCE
feature.
This patch set enables this feature in virtio pmd, to support VM running virtio
pmd be migrated without vhost supporting RARP generation.
v2:
- Use spaces instead of tabs between the code and comments.
- Remove unnecessary parentheses.
- Use rte_pktmbuf_mtod directly to get eth_hdr addr.
- Fix virtio_dev_pause return value check.
