  From DPDK-22.07, vhost async dequeue is supported in both split and
packed ring, so modify basic_4k_pages_dsa_test_plan to test vhost async
dequeue feature.

-vhost async operation with DSA driver using 4K-pages test plan
-===============================================================

+Basic 4k-pages test with DSA driver test plan
+==============================================
 
 Description
 ===========
 
-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.
+DPDK 19.02 add support for using virtio-user without hugepages. The --no-huge mode was augmented to use memfd-backed
+memory (on systems that support memfd), to allow using virtio-user-based NICs without hugepages.
 
 This document provides the test plan for testing some basic functions when Vhost-user using asynchronous data path with
 DSA driver (kernel IDXD driver and DPDK vfio-pci driver) and using 4K-pages memory environment.
-1. test Vhost asynchronous data path with DSA driver in the PVP topology environment with testpmd.
-2. check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring 
+1. Test Vhost asynchronous data path with DSA driver in the PVP topology environment with testpmd.
+2. Check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring
 vhost-user/virtio-net mergeable path.
 3.Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring
 and packed ring vhost-user/virtio-net mergeable and non-mergeable path.
 4. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring.
 5. Vhost-user using 1G hugepges and virtio-user using 4k-pages.

 Note:
 1. When DMA devices are bound to vfio driver, VA mode is the default and recommended. For PA mode, page by page mapping may
 exceed IOMMU's max capability, better to use 1G guest hugepage.

-4. On VM1, set virtio device IP and run arp protocal::
-
-	<VM1># ethtool -L ens5 combined 16
-	<VM1># ifconfig ens5 1.1.1.2
-	<VM1># arp -s 1.1.1.8 52:54:00:00:00:02
-
-5. On VM2, set virtio device IP and run arp protocal::
-
-	<VM2># ethtool -L ens5 combined 16
-	<VM2># ifconfig ens5 1.1.1.8
-	<VM2># arp -s 1.1.1.2 52:54:00:00:00:01
-
-6. Scp 1MB file form VM1 to VM2::
-
-	<VM1># scp <file>> root@1.1.1.8:/
-
-7. Check the iperf performance between two VMs by below commands::
-
-	<VM1># iperf -s -i 1
-	<VM2># iperf -c 1.1.1.2 -i 1 -t 60
+	<VM2># ethtool -L ens5 combined 4
