+PVP vhost/virtio-pmd async data-path perf test plan
+===================================================
+
+Description
+===========
+
+Benchmark pvp qemu test with vhost async data-path.
+
+Test flow
+=========
+
+TG --> NIC --> Vhost --> Virtio--> Vhost --> NIC --> TG
+
+Test Case 1: pvp split ring vhost async test with 1core 1queue using idxd kernel driver
+---------------------------------------------------------------------------------------
+
+1. Bind one nic port to vfio-pci and 1 dsa device to idxd, then generate 2wq by below command::
+
+ ./usertools/dpdk-devbind.py -b vfio-pci 0000:29:00.0
+ ./usertools/dpdk-devbind.py -b idxd 0000:6a:01.0
+ ./drivers/dma/idxd/dpdk_idxd_cfg.py -q 2 0
+
+2. Launch vhost testpmd by below command::
+
+ ./build/app/dpdk-testpmd -n 8 -l 9-10 --file-prefix=dpdk_vhost --huge-dir=/dev/hugepages -a 0000:29:00.0 --socket-mem 8192 \
+ --vdev 'net_vhost,iface=./vhost-net,queues=1,dmas=[txq0@wq0.0;rxq0@wq0.1]' \
+ --iova=va -- -i --nb-cores=1 --txq=1 --rxq=1 --txd=2048 --rxd=2048 --forward-mode=mac -a
+
