100. vhost/virtio-user loopback server mode test plan

Virtio-user server mode is a feature to enable virtio-user as the server, vhost as the client, thus after vhost-user is killed then relaunched, virtio-user can reconnect back to vhost-user again; at another hand, virtio-user also can reconnect back to vhost-user after virtio-user is killed. This feature test need cover different rx/tx paths with virtio 1.0 and virtio 1.1, includes split ring mergeable, non-mergeable, inorder mergeable, inorder non-mergeable, vector_rx path and packed ring mergeable, non-mergeable, inorder non-mergeable, inorder mergeable, vectorized path.

100.1. Test Case 1: Basic test for packed ring server mode

  1. Launch virtio-user as server mode:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 --no-pci --file-prefix=virtio \
--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=1,packed_vq=1 -- -i --rxq=1 --txq=1 --no-numa
>set fwd mac
>start

  2. Launch vhost as client mode:

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 3-4 -n 4 --no-pci --file-prefix=vhost \
--vdev 'net_vhost0,iface=/tmp/sock0,client=1,queues=1' -- -i --rxq=1 --txq=1 --nb-cores=1
>set fwd mac
>start tx_first 32

  3. Run below command to get throughput,verify the loopback throughput is not zero:

    testpmd>show port stats all
