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:

    AVX512 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

Test flow
=========

TG --> NIC --> Vhost --> Virtio--> Vhost --> NIC --> TG
