-Test Case 12: split virtqueue vm2vm non-mergeable path multi-queues payload check with cbdma enabled
-====================================================================================================
-
-1. bind 4 cbdma port to vfio-pci and launch vhost by below command::
-
-    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 \
-    --vdev 'eth_vhost0,iface=vhost-net,queues=2,client=1,dmas=[txq0@0000:80:04.0;txq1@0000:80:04.1]' --vdev 'eth_vhost1,iface=vhost-net1,queues=2,client=1,dmas=[txq0@0000:80:04.2;txq1@0000:80:04.3]' \

-still need one ring put header. So check 504 packets and 48128 bytes received by virtio-user1 and 502 packets with 64 length and 2 packets with 8K length in pdump-virtio-rx.pcap.

-Test Case 24: packed virtqueue vm2vm vectorized-tx path multi-queues test indirect descriptor
-=============================================================================================
-
-1. Launch vhost by below command::

-    -i --nb-cores=1 --no-flush-rx
-
-2. Launch virtio-user1 by below command::

-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.
