vhost/virtio-user loopback with multi-queues test plan
======================================================

This test plan test loopback multi-queues with split virtqueue mergeable, non-mergeable, vectorized_rx,
inorder mergeable, inorder non-mergeable path, and packed virtqueue mergeable, non-mergeable，inorder mergeable,
inorder non-mergeable, vectorized path. And virtio-user support 8 queues in maximum, check performance could be
linear growth when enable 8 queues and 8 cores, notice cores should in same socket.

Test Case 1: loopback with virtio 1.1 mergeable path using 1 queue and 8 queues
===============================================================================

1. Launch testpmd by below command::

    rm -rf vhost-net*
    ./<build_target>/app/dpdk-testpmd -l 1-2 -n 4 --no-pci \
    --vdev 'eth_vhost0,iface=vhost-net,queues=1' -- \
    -i --nb-cores=1 --txd=1024 --rxd=1024
    testpmd>set fwd mac

2. Launch virtio-user by below command::

    ./<build_target>/app/dpdk-testpmd -n 4 -l 5-6 \
    --no-pci --file-prefix=virtio \

    -- -i --nb-cores=1 --txd=1024 --rxd=1024
    testpmd>set fwd mac
    testpmd>start

3. Send packets with vhost-testpmd,[frame_size] is the parameter changs in [64, 1518]::

    testpmd>set txpkts [frame_size]
    testpmd>start tx_first 32

4. Get throughput 10 times and calculate the average throughput::

    testpmd>show port stats all

    testpmd>stop
    testpmd>quit

5. Check each RX/TX queue has packets, then quit testpmd::

    testpmd>stop
    testpmd>quit

6. Launch testpmd by below command::

    rm -rf vhost-net*
    ./<build_target>/app/dpdk-testpmd -l 1-9 -n 4 --no-pci --vdev 'eth_vhost0,iface=vhost-net,queues=8' -- \
    -i --nb-cores=8 --rxq=8 --txq=8 --txd=1024 --rxd=1024
    testpmd>set fwd mac

7. Launch virtio-user by below command::

    ./<build_target>/app/dpdk-testpmd -n 4 -l 10-18 \
    --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,queues=8,packed_vq=1,mrg_rxbuf=0,in_order=1,vectorized=1 \
    -- -i --rx-offloads=0x10 --nb-cores=8 --rxq=8 --txq=8 --txd=1024 --rxd=1024
    testpmd>set fwd mac
    testpmd>start

8. Send packets with vhost-testpmd,[frame_size] is the parameter changs in [64, 128, 256, 512, 1024, 1518]::

    testpmd>set txpkts [frame_size]
    testpmd>start tx_first 32

9. Get throughput 10 times and calculate the average throughput，check the throughput of 8 queues is eight times of 1 queue::
