 6. Change dest IP address to fixed ip, packets will distribute to 1 queue, check l3fwd-power log that only one related core is waked up.
 
 7. Stop the date transmitter, check all related core will be back to sleep status.

+Test Case 4: Packed ring virtio interrupt test with 16 queues
+=============================================================
+
+1. Bind one NIC port to igb_uio, then launch testpmd by below command::
+
+    rm -rf vhost-net*
+    ./testpmd -c 0x1ffff -n 4 --socket-mem 1024 1024 --vdev 'eth_vhost0,iface=vhost-net,queues=16' -- -i --nb-cores=16 --rxq=16 --txq=16 --rss-ip
+
+2. Launch VM1, set queues=16, vectors>=2xqueues+2, mq=on::
+
+    taskset -c 34-35 \
+    qemu-system-x86_64 -name us-vhost-vm2 \
+     -cpu host -enable-kvm -m 2048 -object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc \
+     -smp cores=16,sockets=1 -drive file=/home/osimg/noiommu-ubt16.img \
+     -monitor unix:/tmp/vm2_monitor.sock,server,nowait -net nic,vlan=2,macaddr=00:00:00:08:e8:aa,addr=1f -net user,vlan=2,hostfwd=tcp:127.0.0.1:6005-:22 \
+     -chardev socket,id=char1,path=./vhost-net -netdev type=vhost-user,id=mynet2,chardev=char1,vhostforce,queues=16 \
+     -device virtio-net-pci,mac=52:54:00:00:00:02,netdev=mynet2,mrg_rxbuf=on,csum=on,mq=on,vectors=40,packed=on  \
+     -vnc :11 -daemonize
+
+3. Bind virtio port to vfio-pci::
+
+    modprobe vfio enable_unsafe_noiommu_mode=1
+    modprobe vfio-pci
+    ./usertools/dpdk-devbind.py --bind=vfio-pci xx:xx.x
+
+4. In VM, launch l3fwd-power sample::
+
+    ./l3fwd-power -c 0x0ffff -n 4 --log-level='user1,7' -- -p 1 -P  --config '(0,0,0),(0,1,1),(0,2,2),(0,3,3)(0,4,4),(0,5,5),(0,6,6),(0,7,7)(0,8,8),(0,9,9),(0,10,10),(0,11,11)(0,12,12),(0,13,13),(0,14,14),(0,15,15)' --no-numa  --parse-ptype
+
+5. Send random dest ip address packets to host nic with packet generator, packets will distribute to all queues, check l3fwd-power log that all related cores are waked up.
+
+6. Change dest IP address to fixed ip, packets will distribute to 1 queue, check l3fwd-power log that only one related core is waked up.
+
+7. Stop the date transmitter, check all related core will be back to sleep status.
