+Vswitch sample can leverage IOAT to accelerate vhost async data-path from dpdk 20.11.
+This plan test vhost DMA operation callbacks for CBDMA PMD and vhost async data-path in vhost sample.
 From 20.11 to 21.02, only split ring support cbdma copy with vhost enqueue direction;
 from 21.05,packed ring also can support cbdma copy with vhost enqueue direction.

 Prerequisites
 =============
 
+Topology
+--------
+	Test flow: TG-->NIC-->VSwitch-->Virtio-->VSwitch-->NIC-->TG
+
+Hardware
+--------
+	Supportted NICs: ALL
+
+Software
+--------
+	Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz
+
+General set up
+--------------
+1. Compile DPDK::
+
+	# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>
+	# ninja -C <dpdk build dir> -j 110
+
+2. Get the PCI device ID and DMA device ID of DUT, for example, 0000:18:00.0 is PCI device ID, 0000:00:04.0, 0000:00:04.1 is DMA device ID::
+
+	<dpdk dir># ./usertools/dpdk-devbind.py -s
+
+	Network devices using kernel driver
+	===================================
+	0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
+
+	DMA devices using kernel driver
+	===============================
+	0000:00:04.0 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci
+	0000:00:04.1 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci
+
+Test case
+=========
+
+Common steps
+------------
+1. Bind 1 NIC port and CBDMA channels to vfio-pci::
+
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>
+	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DMA device id>
+
+	For example, Bind 1 NIC port and 2 CBDMA channels::
+	./usertools/dpdk-devbind.py -b vfio-pci 0000:00:18.0
+	./usertools/dpdk-devbind.py -b vfio-pci 0000:00:04.0,0000:00:04.1
+
+2. Inject imix packets to NIC by traffic generator::
+
+	The packet size include [64, 128, 256, 512, 1024, 1518], and the format of packet is as follows.
+	+-------------+-------------+-------------+-------------+
+	| MAC         | MAC         | IPV4        | IPV4        |
+	| Src address | Dst address | Src address | Dst address |
+	|-------------|-------------|-------------|-------------|
+	| Any MAC     | Virtio mac  | Any IP      | Any IP      |
+	+-------------+-------------+-------------+-------------+
+	All the packets in this test plan use the Virtio mac:00:11:22:33:44:10.
 
 Test Case1: PVP performance check with CBDMA channel using vhost async driver
-=============================================================================
+-----------------------------------------------------------------------------
