49. vhost/virtio loopback with multi-paths and port restart test plan

This test plan includes split virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path, and packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable path test. Also test port restart and only send one packet each time using testpmd.

49.1. Test Case 1: loopback test with packed ring mergeable path

  1. Launch vhost by below command:

    rm -rf vhost-net*
./testpmd -n 4 -l 2-4  --socket-mem 1024,1024 --legacy-mem --no-pci \
--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0' -- -i --nb-cores=1 --txd=1024 --rxd=1024
testpmd>set fwd mac

  2. Launch virtio-user by below command:
