+Test Case9: LSC event between vhost-user and virtio-user with packed ring and cbdma enabled
+==========================================================================================

+flow: Vhost <--> Virtio
+
+1. Bind one cbdma port to igb_uio driver, then start vhost-user side::
+
+    ./testpmd -c 0x3000 -n 4 -w 00:04.0 --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0,dmas=[txq0@00:04.0]' -- -i
+    testpmd>set fwd mac
+    testpmd>start
+
+2. Start virtio-user side::
+
+    ./testpmd -c 0xc000 -n 4 --no-pci --file-prefix=virtio --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,packed_vq=1 -- -i --tx-offloads=0x00
+    testpmd>set fwd mac
+    testpmd>start
+
+3. Check the virtio-user side link status::
+
+    testpmd> show port info 0
+    #it should show "up"
+
+4. Quit the vhost-user side with testpmd, then check the virtio-user side link status::
+
+    testpmd> show port info 0
+    #it should show "down"

+1. Bind one cbdma port and one NIC port to igb_uio, launch testpmd with a virtual vhost device as backend::
