 vm2vm vhost-user/virtio-pmd test plan
 =====================================
 
-Description
-===========
+This test plan includes vm2vm vhost-user/virtio-pmd(0.95) mergeable ,normal and vector_rx path test, and vm2vm vhost/virtio-pmd(1.0) mergeable,
+normal and vector_rx path test. Specially, two mergeable path test check the payload of each packets are valid by using pdump.
