+vhost event idx interrupt mode test plan
+========================================
+
+Description
+===========
+
+Vhost event idx interrupt need test with l3fwd-power sample, send small packets from virtio-net to vhost side，check vhost-user cores can be wakeup status，and vhost-user cores should be sleep status after stop sending packets from virtio side.
+
+Test flow
+=========
+
+Virtio-net --> Vhost-user
+
+Test Case 1: wake up vhost-user core with event idx interrupt mode
+==================================================================
+
+1. Launch l3fwd-power example app with client mode::
+
+    ./l3fwd-power -l 1 \
+    -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci\
+    --log-level=9 \
+    --vdev 'eth_vhost0,iface=/vhost-net0,queues=1,client=1' \
+    -- -p 0x1 \
+    --parse-ptype 1 \
+    --config "(0,0,1)"
+
+2. Launch VM1 with server mode::
+
+     taskset -c 33 \
+     qemu-system-x86_64 -name us-vhost-vm1 \
+     -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 -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:127.0.0.1:6001-:22 \
+     -smp cores=1,sockets=1 -drive file=/home/osimg/ubuntu16.img  \
+     -chardev socket,server,id=char0,path=/vhost-net0 \
+     -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
+     -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,csum=on -vnc :10 -daemonize
+
+3. Relauch l3fwd-power sample for port up::
+
+    ./l3fwd-power -l 0-3 \
+    -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci\
+    --log-level=9 \
+    --vdev 'eth_vhost0,iface=/vhost-net0,queues=1,client=1' \
+    -- -p 0x1 \
+    --parse-ptype 1 \
+    --config "(0,0,1)"
+
+3.  On VM, set ip for virtio device and send packets to vhost by cmds::
+
+    ifconfig [ens3] 1.1.1.2
+    #[ens3] is the virtual device name
+    ping 1.1.1.3
+    #send packets to vhost
+
+4. Check vhost related core is waked up by reading l3fwd-power log.
+
+Test Case 2: wake up vhost-user cores with event idx interrupt mode 16 queues test
+==================================================================================
+
+1. Launch l3fwd-power example app with client mode::
+
+    ./l3fwd-power -l 1-16 \
+    -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci\
+    --log-level=9 \
+    --vdev 'eth_vhost0,iface=/vhost-net0,queues=16,client=1' \
+    -- -p 0x1 \
+    --parse-ptype 1 \
+    --config "(0,0,1),(0,1,2),(0,2,3),(0,3,4),(0,4,5),(0,5,6),(0,6,7),(0,7,8),(0,8,9),(0,9,10),(0,10,11),(0,11,12),(0,12,13),(0,13,14),(0,14,15),(0,15,16)"
+
+2. Launch VM1 with server mode::
+
+     taskset -c 17-18 \
+     qemu-system-x86_64 -name us-vhost-vm1 \
+     -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 -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:127.0.0.1:6001-:22 \
+     -smp cores=16,sockets=1 -drive file=/home/osimg/ubuntu16.img  \
+     -chardev socket,server,id=char0,path=/vhost-net0 \
+     -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=16 \
+     -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,csum=on,mq=on,vectors=40 -vnc :10 -daemonize
+
+3. Relauch l3fwd-power sample for port up::
+
+    ./l3fwd-power -l 1-16 \
+    -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci\
+    --log-level=9 \
+    --vdev 'eth_vhost0,iface=/vhost-net0,queues=16,client=1' \
+    -- -p 0x1 \
+    --parse-ptype 1 \
+    --config "(0,0,1),(0,1,2),(0,2,3),(0,3,4),(0,4,5),(0,5,6),(0,6,7),(0,7,8),(0,8,9),(0,9,10),(0,10,11),(0,11,12),(0,12,13),(0,13,14),(0,14,15),(0,15,16)"
+
+3.  Set vitio-net with 16 quques and give vitio-net ip address::
+
+    ethtool -L [ens3] combined 16    # [ens3] is the name of virtio-net
+    ifconfig [ens3] 1.1.1.1
+
+4.  Send packets with different IPs from virtio-net, notice to bind each vcpu to different send packets process::
+
+    taskset -c 0 ping 1.1.1.2
+    taskset -c 1 ping 1.1.1.3
+    taskset -c 2 ping 1.1.1.4
+    taskset -c 3 ping 1.1.1.5

+    taskset -c 9 ping 1.1.1.2
+    taskset -c 10 ping 1.1.1.2
+    taskset -c 11 ping 1.1.1.2
+    taskset -c 12 ping 1.1.1.2
+    taskset -c 13 ping 1.1.1.2
+    taskset -c 14 ping 1.1.1.2
+    taskset -c 15 ping 1.1.1.2
+
+5.  Check vhost related cores are waked up with l3fwd-power log, such as following::
+
+    L3FWD_POWER: lcore 0 is waked up from rx interrupt on port 0 queue 0
+    .....
+    .....
+    L3FWD_POWER: lcore 15 is waked up from rx interrupt on port 0 queue 15
+
+Test Case 3: wake up vhost-user cores by multi virtio-net in VMs with event idx interrupt mode
+==============================================================================================
+
+1. Launch l3fwd-power example app with client mode::
+
+    ./l3fwd-power -l 1-2 \
