 =====================================
 
 Description
 ===========
 
-Test cases for vhost-user + virtio-net vm2vm tso/tso zero-copy/ufo/tso_ufo capability check.
+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.
