@@ -41,6 +41,7 @@ This test plan test several features in VM2VM topo:
 1. Split virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test.
 2. Packed virtqueue vm2vm in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vectorized path (ringsize not powerof 2) test.
 3. Split ring and packed ring vm2vm test when vhost enqueue operation with multi-CBDMA channels.
+Note: Blow cases 12-16 which have cbdma usage should add dpdk local path to support async vhostpmd.
