+vm2vm vhost-user/virtio-user test plan
+======================================
+
+Description
+===========
+
+This test plan includes split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test, and packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable path test. This plan also check the payload of packets is accurate. For packed virtqueue test, need using qemu version > 4.2.0.
+
+Prerequisites
+=============
+
+Enable pcap lib in dpdk code and recompile::

+
+Test Case 1: packed virtqueue vm2vm mergeable path test
+=======================================================
+

 Description
 ===========
 
-The feature enabled the DPDK Vhost TX offload (TSO and UFO). The feature added the negotiation between DPDK user space vhost and virtio-net, so we will verify the TSO/cksum in the TCP/IP stack enabled environment and UFO/cksum in the UDP/IP stack enabled environment with vm2vm vhost-user/virtio-net normal path. Also add case to check the payload of large packet is valid by scp with vm2vm vhost-user/virtio-net mergeable path test.
+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 non-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 dequeue zero copy test. For packed virtqueue test, need using qemu version > 4.2.0.
