There is already similar patch series from Ciara: https://patchwork.ozlabs.org/project/openvswitch/list/?series=157685 I just had no enough time to get to them.

OK thanks! I will take a look William

When enabling RTE_LIBRTE_PMD_PCAP in DPDK, we need to link the libpcap library, otherwise 'make' will fail. I'm using this for creating a pcap-based device which read pcap file infinitely to rx queue, acting like a traffic generator. Example: $ ovs-vsctl add-port br0 tg0 -- set int tg0 type=dpdk \ options:dpdk-devargs=vdev:net_pcap0,rx_pcap=p0.pcap,infinite_rx=1 The p0.pcap is replayed into the rx queue of tg0, generating traffic rate around 8Mpps into OVS when OVS is doing drop.
