100. vhost/virtio-user pvp with multi-queues and port restart test plan

100.1. Description

This test plan test vhost/virtio-user pvp multi-queues with split virtqueue and packed virtqueue different rx/tx paths, includes split virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test, and packed virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable and vectorized path, also cover port restart test with each path.

100.2. Test flow

TG –> NIC –> Vhost –> Virtio–> Vhost –> NIC –> TG

100.3. Test Case 1: pvp 2 queues test with packed ring mergeable path

  1. Bind one port to igb_uio, then launch vhost by below command:

    rm -rf vhost-net*
    ./testpmd -n 4 -l 2-4  \
    --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=2,client=0' -- -i --nb-cores=2 --rxq=2 --txq=2
    testpmd>set fwd mac
    testpmd>start
    
  2. Launch virtio-user by below command:

    ./testpmd -n 4 -l 5-7 \
    --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,queues=2,packed_vq=1,mrg_rxbuf=1,in_order=0,queue_size=255 \
