 vhost/virtio loopback with multi-paths and port restart test plan
 =================================================================
 
-This test plan includes split virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path, and packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable path test. Also test port restart and only send one packet each time using testpmd.
+This test plan includes split virtqueue mergeable, non-mergeable, vectorized_rx,
+inorder mergeable, inorder non-mergeable path, and packed virtqueue mergeable,
+non-mergeable，inorder mergeable, inorder non-mergeable, vectorized path test.
+Also test port restart and only send one packet each time using testpmd.
+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
