+==================================================================
+PVP vhost/virtio multi-paths async data-path performance test plan
+==================================================================
+
+Benchmark PVP multi-paths performance with 10 tx/rx paths when vhost uses the asynchronous operation. Includes mergeable, 
+non-mergeable, vectorized_rx, inorder mergeable, inorder non-mergeable, packed ring mergeable, packed ring non-mergeable，
+packed ring inorder mergeable, packed ring inorder non-mergeable, virtio1.1 vectorized path. Give 1 core for vhost and virtio 
+respectively. Packed ring vectorized path need:
+
+    AVX512F and required extensions are supported by compiler and host
+    VERSION_1 and IN_ORDER features are negotiated
+    mergeable feature is not negotiated
+    LRO offloading is disabled
+
+Split ring vectorized rx path need:
+    mergeable and IN_ORDER features are not negotiated
+    LRO, chksum and vlan strip offloadings are disabled
