+Test Case5: vf multi-queue interrupt with vfio-pci on i40e 
+==========================================================
+
+1. Generate NIC VF, then bind it to vfio drvier::
+
+    echo 1 > /sys/bus/pci/devices/0000\:04\:00.0/sriov_numvfs
+    modprobe vfio-pci
+    usertools/dpdk-devbind.py --bind=vfio-pci 0000:04:10.0(vf_pci)
+
+  Notice:  If your PF is kernel driver, make sure PF link is up when your start testpmd on VF.
+
+2. Start l3fwd-power with VF::
+
+    examples/l3fwd-power/build/l3fwd-power -c 3f -n 4 -m 2048 -- -P -p 0x1 --config="(0,0,1),(0,1,2),(0,2,3),(0,3,4)"
+
+3. Send UDP packets with random ip and dest mac = vf mac addr::
+
+      for x in range(0,10):
+       sendp(Ether(src="00:00:00:00:01:00",dst="vf_mac")/IP(src='2.1.1.' + str(x),dst='2.1.1.5')/UDP()/"Hello!0",iface="tester_intf")
+
+4. Check if threads on all cores have waked up::
+
+    L3FWD_POWER: lcore 1 is waked up from rx interrupt on port 0 queue 0
+    L3FWD_POWER: lcore 2 is waked up from rx interrupt on port 0 queue 1
+    L3FWD_POWER: lcore 3 is waked up from rx interrupt on port 0 queue 2
+    L3FWD_POWER: lcore 4 is waked up from rx interrupt on port 0 queue 3
+
+Test Case6: VF multi-queue interrupt in VM with vfio-pci on i40e
+================================================================
+    
+1. Generate NIC VF, then bind it to vfio drvier::
+
+    echo 1 > /sys/bus/pci/devices/0000\:88:00.1/sriov_numvfs
+    modprobe vfio-pci
+    usertools/dpdk-devbind.py --bind=vfio-pci 0000:88:0a.0(vf_pci)
+
+  Notice:  If your PF is kernel driver, make sure PF link is up when your start testpmd on VF.
+
+2. Passthrough VF 0 to VM0 and start VM0::
+
+    taskset -c 4,5,6,7,8 qemu-system-x86_64 \
+    -name vm0 -enable-kvm -pidfile /tmp/.vm0.pid -daemonize -monitor unix:/tmp/vm0_monitor.sock,server,nowait \
+    -device e1000,netdev=nttsip1  -netdev user,id=nttsip1,hostfwd=tcp:127.0.0.1:6000-:22 \
+    -device vfio-pci,host=0000:88:0a.0,id=pt_0 -cpu host -smp 5 -m 10240 \
+    -chardev socket,path=/tmp/vm0_qga0.sock,server,nowait,id=vm0_qga0 -device virtio-serial \
+    -device virtserialport,chardev=vm0_qga0,name=org.qemu.guest_agent.0 -vnc :11 \
+    -drive file=/home/osimg/noiommu-ubt16.img,format=qcow2,if=virtio,index=0,media=disk
+
+  Notice: VM needs Kernel version > 4.8.0, mostly linux distribution don't support vfio-noiommu mode by default, so testing this case need rebuild kernel to enable vfio-noiommu.
+
+3. Bind VF 0 to the vfio-pci driver::
+
+    modprobe -r vfio_iommu_type1
+    modprobe -r vfio
+    modprobe vfio enable_unsafe_noiommu_mode=1
+    modprobe vfio-pci
+    usertools/dpdk-devbind.py -b vfio-pci 0000:00:04.0
+
+4.Start l3fwd-power in VM::
+
+    ./build/l3fwd-power -l 0-3 -n 4 -m 2048 -- -P -p 0x1 --config="(0,0,0),(0,1,1),(0,2,2),(0,3,3)"
+
+5. Send UDP packets with random ip and dest mac = vf mac addr::
+
+    for x in range(0,10):
+     sendp(Ether(src="00:00:00:00:01:00",dst="vf_mac")/IP(src='2.1.1.' + str(x),dst='2.1.1.5')/UDP()/"Hello!0",iface="tester_intf")
+
+6. Check if threads on core 0 to core 3 can be waked up in VM::
+
+    L3FWD_POWER: lcore 0 is waked up from rx interrupt on port 0 queue 0
+    L3FWD_POWER: lcore 1 is waked up from rx interrupt on port 0 queue 1
+    L3FWD_POWER: lcore 2 is waked up from rx interrupt on port 0 queue 2
+    L3FWD_POWER: lcore 3 is waked up from rx interrupt on port 0 queue 3
