So does OVS in this case is able to apply OpenFlow rules on packets? When netdev_dpdk_vdpa_rxq_recv() is invoked, does the batch of packets go into OVS's parse, lookup, action pipeline? Or all packets go directly into VM if (VF -> VM) and vice versa? Is fwd_rx = netdev_dpdk_vdpa_rxq_recv_impl(dev->relay, rxq->queue_id); forward packets from vhost-user to VF and ret = netdev_dpdk_rxq_recv(rxq, batch, qfill); forward packets from vhost-user to VM?
