+Test Case3: CBDMA threshold value check
+========================================
+
+1. Bind four cbdma port to igb_uio, then 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@80:04.0;txq1@80:04.1],dmathr=512' --vdev 'eth_vhost1,iface=vhost-net1,queues=2,client=1,dmas=[txq0@80:04.2;txq1@80:04.3],dmathr=4096' -- \
+    -i --nb-cores=1 --rxq=2 --txq=2
+    >start
+
+2. Launch virtio-user1::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 7-8 \
+    --no-pci --file-prefix=virtio1 \
+    --vdev=net_virtio_user1,mac=00:01:02:03:04:05,path=./vhost-net1,queues=2,server=1,packed_vq=0,mrg_rxbuf=1,in_order=0,queue_size=4096 \
+    -- -i --nb-cores=1 --rxq=2 --txq=2
+    >start
+
+3. Launch virtio-user0::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 5-6 \
+    --no-pci --file-prefix=virtio \
+    --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,queues=2,server=1,packed_vq=0,mrg_rxbuf=1,in_order=0,queue_size=4096 \
+    -- -i --nb-cores=1 --rxq=2 --txq=2
+    >start
+  
+4. Check the cbdma threshold value for each vhost port can be config correct from vhost log::
+
+    dma parameters: vid0,qid0,dma*,threshold:512
+    dma parameters: vid0,qid2,dma*,threshold:512
+    dma parameters: vid1,qid0,dma*,threshold:4096
+    dma parameters: vid1,qid2,dma*,threshold:4096
