Verify that four separated vxlan packets received on PF devices.
Make sure tcp packet payload is 256, 256, 256 and 124.

+Test Case: Vxlan Sample Performance Benchmarking
+================================================
+The throughput is measured for different operations taken by vxlan sample.
+Virtio single mean there's only one flow and forwarded by single port in vm.
+Virtio two mean there're two flows and forwarded by both two ports in vm.
