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.
