The test cases cover split ring and packed ring.\n-Notice:\n-\n-* All packed ring case need special qemu version.\n-* In the PVP case, when packet size is 1518B, 10G nic could be the performance bottleneck, so we use 40G traffic genarator and 40G nic.\n-* Also as vhost zero copy mbufs should be consumed as soon as possible, don't start send packets at vhost side before VM and virtio-pmd launched.\n-\n-Test flow\n-=========\n-\n-TG --> NIC --> Vhost --> Virtio --> Vhost --> NIC --> TG\n-\n-Test Case 1: pvp split ring dequeue zero-copy test\n-==================================================\n-\n-1.
