He, Xingguang Sept. 6, 2022, 11:22 a.m. UTC 
  From DPDK-22.07, vhost async dequeue is supported in both split and
packed ring, so modify pvp_vhost_dsa_test_plan to test vhost async
dequeue feature.

-Test Case 25: PVP split and packed ring dynamic queues vhost async operation with dsa dpdk and kernel driver channels
+Test Case 13: PVP split and packed ring dynamic queues vhost async operation with dsa dpdk and kernel driver channels
 -----------------------------------------------------------------------------------------------------------------------
-This case uses testpmd and Traffic Generator(For example, Trex) to test split ring and packed ring when vhost uses the asynchronous enqueue
-operations with both dsa dpdk driver and dsa kernel driver and if the vhost-user can work well when the queue number dynamic change.
-Both iova as VA mode have beed tested.
+This case tests if the vhost-user async operation with dsa kernel driver and dsa dpdk driver can work normally when the queue number of split ring and packed ring dynamic change.
