From DPDK-22.07, virtio support async dequeue for split and packed ring
path, so modify vswitch_sample_cbdma testplan to test the split and
packed ring async dequeue feature.

+Vswitch sample can leverage DMA 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.
+From 22.07, split and packed ring support cbdma copy with both vhost enqueue and deuque direction.
+
+--dmas This parameter is used to specify the assigned DMA device of a vhost device. Async vhost-user
+net driver will be used if --dmas is set. For example –dmas [txd0@00:04.0,txd1@00:04.1,rxd0@00:04.2,rxd1@00:04.3]
+means use DMA channel 00:04.0/00:04.2 for vhost device 0 enqueue/dequeue operation and use DMA channel
+00:04.1/00:04.3 for vhost device 1 enqueue/dequeue operation. The index of the device corresponds to
+the socket file in order, that means vhost device 0 is created through the first socket file,
+vhost device 1 is created through the second socket file, and so on.
+For more about vswitch example, please refer to the DPDK docment:http://doc.dpdk.org/guides/sample_app_ug/vhost.html

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
+ ifconfig ens5 1.1.1.2
+ arp -s 1.1.1.8 52:54:00:00:00:02
6. On VM2, set virtio device IP and run arp protocal::
- ifconfig ens5 1.1.1.8
- arp -s 1.1.1.2 52:54:00:00:00:01
+ ifconfig ens5 1.1.1.8
+ arp -s 1.1.1.2 52:54:00:00:00:01
7. Check the iperf performance between two VMs by below commands::
- Under VM1, run: `iperf -s -i 1`
- Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
+ Under VM1, run: `iperf -s -i 1`
+ Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
8. Check iperf throughput can get x Gbits/sec.
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
+ Under VM1, run: `scp [xxx] root@1.1.1.8:/` [xxx] is the file name
10. Rerun step 7-9 five times.
