+Vswitch Vhost-user async driver test plan
+=========================================
+
+Description
+===========
+
+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
