Ling, WeiX July 29, 2022, 8:13 a.m. UTC 
  From DPDK-22.07, virtio support async dequeue for split and packed ring
path, so modify vm2vm_virtio_net_perf_cbdma testplan to test the split
and packed ring async dequeue feature.

 Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an asynchronous way.
 In addition, vhost supports M:N mapping between vrings and DMA virtual channels. Specifically, one vring can use multiple different DMA
-channels and one DMA channel can be shared by multiple vrings at the same time.Vhost enqueue operation with CBDMA channels is supported
-in both split and packed ring.
