103. Loopback vhost/virtio multi-paths async data-path test plan

Benchmark vhost/virtio-user loopback test with 10 tx/rx paths when vhost uses the asynchronous operation. Includes split ring mergeable, non-mergeable, vector_rx, inorder mergeable, inorder non-mergeable, packed ring mergeable, packed ring non-mergeable， packed ring inorder mergeable, packed ring inorder non-mergeable path and vectorized path.

103.1. Test case

103.1.1. Common steps

  1. Bind 1 dsa device to idxd, then generate 1wq by below command:

    ./usertools/dpdk-devbind.py -b idxd 0000:6a:01.0
./drivers/dma/idxd/dpdk_idxd_cfg.py -q 2 0
