How reproducible:


Steps to Reproduce:
1. Build ovs dpdk pvp topo:
Bridge ovsbr0
        datapath_type: netdev
        Port dpdk0
            Interface dpdk0
                type: dpdk
                options: {dpdk-devargs="0000:07:00.0", n_rxq="1", n_rxq_desc="1024", n_txq_desc="1024"}
        Port vhost0
            Interface vhost0
                type: dpdkvhostuserclient
                options: {vhost-server-path="/tmp/vhostuser/vhost0"}
        Port dpdk1
            Interface dpdk1
                type: dpdk
                options: {dpdk-devargs="0000:07:00.1", n_rxq="1", n_rxq_desc="1024", n_txq_desc="1024"}
        Port ovsbr0
            Interface ovsbr0
                type: internal
        Port vhost1
            Interface vhost1
                type: dpdkvhostuserclient
                options: {vhost-server-path="/tmp/vhostuser/vhost1"}
