+=========================================================================================
+
+1. Bind four cbdma channels and one nic port to igb_uio, then launch vhost by below command::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 28-29 \
+ --file-prefix=vhost --vdev 'net_vhost0,iface=/tmp/s0,queues=2,client=1,dmas=[txq0@80:04.5;txq1@80:04.6],dmathr=1024' \
+ -- -i --nb-cores=1 --txd=1024 --rxd=1024 --txq=2 --rxq=2
+ >set fwd mac

+
+2. Launch virtio-user by below command::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 30-31 --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=/tmp/s0,mrg_rxbuf=1,in_order=1,queues=2,server=1,packed_vq=1 \

+ >set fwd mac
+ >start
+
+3. Send imix packets [64,1518] from packet generator with random ip, check perforamnce can get target.
+
+4. Stop vhost port, check vhost RX and TX direction both exist packtes in two queues from vhost log.
+
+5. On virtio-user side, dynamic change rx queue numbers from 2 queue to 1 queues, then check one queue RX/TX can work normally::
+
+ testpmd>port stop all
+ testpmd>port config all rxq 1
+ testpmd>port config all txq 1
+ testpmd>port start all
+ testpmd>start
+ testpmd>show port stats all
+
+6. Relaunch virtio-user with vectorized path and 2 queues::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 30-31 --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=/tmp/s0,mrg_rxbuf=0,in_order=1,vectorized=1,queues=2,server=1,packed_vq=1 \
+ -- -i --nb-cores=1 --txd=1024 --rxd=1024 --txq=2 --rxq=2
+ >set fwd mac
+ >start
+
+7. Send imix packets [64,1518] from packet generator with random ip, check perforamnce can get target.
+
+8. Stop vhost port, check vhost RX and TX direction both exist packtes in queue0 from vhost log.
+
+9. On vhost side, dynamic change rx queue numbers from 2 queue to 1 queues, then check one queue RX/TX can work normally::
+
+ testpmd>port stop all
+ testpmd>port config all rxq 1
+ testpmd>port config all txq 1
+ testpmd>port start all
+ testpmd>start
+ testpmd>show port stats all
+
+10. Relaunch vhost with another two cbdma channels and 2 queueus, check perforamnce can get target::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 28-29 \
+ --file-prefix=vhost --vdev 'net_vhost0,iface=/tmp/s0,queues=2,client=1,dmas=[txq0@00:04.5;txq1@00:04.6],dmathr=512' \
+ -- -i --nb-cores=1 --txd=1024 --rxd=1024 --txq=2 --rxq=2
+ >set fwd mac
+ >start
+
+11. Stop vhost port, check vhost RX and TX direction both exist packtes in two queues from vhost log.
