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. v11: - Add check for parameter and tailroom in rte_net_make_rarp_packet. - Allocate mbuf in rte_net_make_rarp_packet. v10: - Add a bold doxygen comment for the experimental function. v9: - Introduce function with the experimental state. v8: - Add a helper in lib/librte_net to make rarp packet, it's used by both vhost and virtio. v7: - Improve comment for state_lock. - Rename spinlock variable 'sl' to 'lock'. v6: - Use rte_pktmbuf_alloc() instead of rte_mbuf_raw_alloc(). - Remove the 'len' parameter in calling virtio_send_command(). - Remove extra space between typo and var. - Improve comment and alignment. - Remove the unnecessary header file. - A better usage of 'unlikely' indication. v5: - Remove txvq parameter in virtio_inject_pkts. - Zero hw->special_buf after using it. - Return the retval of tx_pkt_burst(). - Allocate a mbuf pointer on stack directly. v4: - Move spinlock lock/unlock into dev_pause/resume. - Separate out a patch for packet injection. v3: - Remove Tx function code duplication, use a special pointer for rarp injection. - Rename function generate_rarp to virtio_notify_peers, replace 'virtnet_' with 'virtio_'. - Add comment for state_lock. - Typo fix and comment improvement. 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.
