 Virtio-user server mode is a feature to enable virtio-user as the server, vhost as the client, thus after vhost-user is killed then relaunched,
 virtio-user can reconnect back to vhost-user again; at another hand, virtio-user also can reconnect back to vhost-user after virtio-user is killed.
 This feature test need cover different rx/tx paths with virtio 1.0 and virtio 1.1, includes split ring mergeable, non-mergeable, inorder mergeable,
-inorder non-mergeable, vector_rx path and packed ring mergeable, non-mergeable, inorder non-mergeable, inorder mergeable path.
+inorder non-mergeable, vector_rx path and packed ring mergeable, non-mergeable, inorder non-mergeable, inorder mergeable, vectorized path.
+Note: Packed virtqueue vectorized path need below three initial requirements:
+    1. AVX512 is allowed in config file and supported by compiler
+    2. Host cpu support AVX512F
+    3. ring size is power of two
