=hn0,queues=4,vhost=on \ -device virtio-net-pci,netdev=hn0,mq=on,guest_tso4=off,guest_tso6=off,guest_ecn=off,guest_ufo=off,vectors=9 In order to use XDP with virtio until LRO is supported TSO must be turned off in the host. The important fields in the above command line are the following, guest_tso4=off,guest_tso6=off,guest_ecn=off,guest_ufo=off Also note it is possible to conusme more queues than can be supported because when XDP is enabled for retransmit XDP attempts to use a queue per cpu. My standard queue count is 'queues=4'. After loading the VM I run the relevant XDP test programs in, ./sammples/bpf For this series I tested xdp1, xdp2, and xdp_tx_iptunnel. I usually test with iperf (-d option to get bidirectional traffic), ping, and pktgen. I also have a modified xdp1 that returns XDP_PASS on any packet to ensure the normal traffic path to the stack continues to work with XDP loaded. It would be great to automate this soon. At the moment I do it by hand which is starting to get tedious. v2: original series dropped trace points after merge. ==================== Acked-by: Michael S.
