-5. Start vhost testpmd, then quit pdump, check 502 packets received by virtio-user1 and 54 packets with 4640 length and 448 packets with 64 length in pdump-virtio-rx.pcap.
+5. Start vhost, then quit pdump and three testpmd, about packed virtqueue vectorized-tx path, it use the indirect descriptors, the 8k length pkt will just occupies one ring.
+So check 256 packets and 56064 bytes received by virtio-user1 and 251 packets with 64 length and 5 packets with 8K length in pdump-virtio-rx.pcap.
