> Thanks William, https://www.kernel.org/doc/Documentation/networking/packet_mmap.txt is very good document for TPACKET_V*, I completely agree TPCKET_V3 is the best way to improve tap and veth performance. Can you share us how to use your patch? Lib/netdev-linux.c is still there, which recv function will be called when I add veth/tap in OVS DPDK?

Hi Yiyang,

To use my patch, simply add a port (ex: veth) by doing
ovs-vsctl add-port br0 afxdp-p0
ovs-vsctl -- set interface afxdp-p0 options:n_rxq=1 type="tpacket"

btw, this is not using OVS-DPDK.
