+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
+
+3. Launch VM with mrg_rxbuf feature on::
+
+    taskset -c 11-18 /usr/local/qemu-7.1.0/bin/qemu-system-x86_64 -name us-vhost-vm1 -cpu host -enable-kvm \
+    -m 8192 -object memory-backend-file,id=mem,size=8192M,mem-path=/mnt/huge,share=on \
+    -numa node,memdev=mem -mem-prealloc -smp cores=8,sockets=1 -drive file=/home/xingguang/osimg/ubuntu22-04.img \
+    -chardev socket,id=char0,path=./vhost-net -monitor unix:/tmp/vm2_monitor.sock,server,nowait -device e1000,netdev=ntts1 \
+    -netdev user,id=n tts1,hostfwd=tcp:127.0.0.1:6002-:22 \

+
+4. Set affinity::
+
+    (qemu)info cpus
+    <host>taskset -cp 11 xxx
+    ...
+    <host>taskset -cp 18 xxx
+
+5. On VM, bind virtio net to vfio-pci and run testpmd::
+
+    mount -t hugetlbfs nodev /mnt/huge
+    modprobe vfio-pci
+    echo 1 > /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
+    ./usertools/dpdk-devbind.py -b vfio-pci 00:04.0
+
+    ./build/app/dpdk-testpmd -c 0x3 -n 8 -- -i --nb-cores=1 --txd=2048 --rxd=2048
+    testpmd>set fwd csum
+    testpmd>start
+
+6. Send tcp/ip packets by packet generator with different packet sizes [64,128,256,512,1024,1280,1518], show throughput with below command::
+
+    testpmd>show port stats all

+
+1. Bind one nic port and 1 dsa device to vfio-pci::
+
+    ./usertools/dpdk-devbind.py -b vfio-pci 0000:29:00.0 0000:6a:01.0
+
+2. Launch vhost testpmd by below command::
+
+    ./build/app/dpdk-testpmd -l 2-4 -n 8 --huge-dir=/dev/hugepages -a 0000:29:00.0 -a 0000:6a:01.0,max_queues=4 --socket-mem 8192 \

+    -- -i --nb-cores=2 --txq=2 --rxq=2 --txd=2048 --rxd=2048 --forward-mode=mac -a
+
+2. Launch VM with mrg_rxbuf feature on::
+
+    taskset -c 11-18 /usr/local/qemu-7.1.0/bin/qemu-system-x86_64 -name us-vhost-vm1 -cpu host -enable-kvm \

+3. Set affinity::
+
+    (qemu)info cpus
+    <host>taskset -cp 11 xxx
+    ...
+    <host>taskset -cp 18 xxx
+
+4. On VM, bind virtio net to vfio-pci and run testpmd::
+
+    mount -t hugetlbfs nodev /mnt/huge
+    modprobe vfio-pci
+    echo 1 > /sys/module/vfio/parameters/enable_unsafe_noiommu_mode

+    testpmd>set fwd csum
+    testpmd>start
+
+5. Send tcp/ip packets by packet generator with different packet sizes [64,128,256,512,1024,1280,1518], show throughput with below command::
+
+    testpmd>show port stats all
