===========
Vswitch sample can leverage IOAT to accelerate vhost async data-path from dpdk 20.11. This plan test
-vhost DMA operation callbacks for CBDMAV PMD and vhost async data-path in vhost sample. Also compare
-the performance between CPU copy, CBDMA copy and Sync copy.
-CPU copy means vhost enqueue w/o cbdma channel; CBDMA copy needs vhost enqueue with cbdma channel
-using parameter '-dmas'; Sync copy needs vhost enqueue with cbdma channel, but threshold ( can be
-adjusted by change value of f.async_threshold in dpdk code) is larger than forwarding packet length.
-
-CBDMA performance indicator
-===========================
-
-(1)CPU copy vs. sync copy delta < 10% for 64B packet size
-(2)CBDMA copy vs sync copy delta > 5% for 1518 packet size
+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;
+from 21.08, split ring support cbdma copy both vhost enqueue and dequeue direction.

+
+5. On VM1, set virtio device IP and run arp protocal::
+
+ ifconfig ens5 1.1.1.2
+ arp -s 1.1.1.8 52:54:00:00:00:02
+

+ arp -s 1.1.1.2 52:54:00:00:00:01
+

+ Under VM1, run: `iperf -s -i 1`
+ Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
+
+8. Check 2VMs can receive and send big packets to each other::
+
+ testpmd>show port xstats all
+ Port 0 should have tx packets above 1522
+ Port 1 should have rx packets above 1522
+
+9. Scp 1MB file form VM1 to VM2M, check packets can be forwarding success by scp::
+
+ Under VM1, run: `scp [xxx] root@1.1.1.8:/` [xxx] is the file name
+
+10. Relaunch vhost-dpdk, then rerun step 7-9 five times.

+=======================================================================
+
+1. Bind one physical ports to vfio-pci and two CBDMA channels to igb_uio.
+
+2. On host, launch dpdk-vhost by below command::
