 Description
 ===========
 
-This test plan test vhost tx offload (TSO and UFO) function by verifing the TSO/cksum in the TCP/IP
-stack enabled environment and UFO/cksum in the UDP/IP stack enabled environment with vm2vm split ring
-and packed ring vhost-user/virtio-net mergeable path. Also add case to check the payload of large packet
-is valid with vm2vm split ring and packed ring vhost-user/virtio-net mergeable and non-mergeable.
-Meanwhile, this plan also check function and performance of split ring enqueue operation with CBDMA channels.
-For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.
+This test plan test several features in VM2VM topo:
+1. Check Vhost tx offload (TSO and UFO) function by verifing the TSO/cksum in the TCP/IP stack and UFO/cksum
+in the UDP/IP stack with vm2vm split ring and packed ring vhost-user/virtio-net mergeable path.
+2. 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.
+3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring.
+4. Check function and performance of split ring enqueue operation with multi-CBDMA channels.
+Note: For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.
