+vhost enqueue interrupt mode test plan
+======================================
+
+Description
+===========
+
+Vhost enqueue interrupt need test with l3fwd-power sample, small packets send from virtio-user to vhost side，
+check vhost-user cores can be wakeup，and vhost-user cores should be back to sleep after stop sending packets from virtio side.
+
+Test Case1:  Wake up vhost-user core with l3fwd-power sample   
+============================================================
+
+1. Launch virtio-user with server mode::
+
+  ./testpmd -l 7-8 -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci --file-prefix=virtio --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=1 -- -i 
+
+2.  Build l3fwd-power sample and launch l3fwd-power with a virtual vhost device::
+
+    ./l3fwd-power -l 0-3 -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci \
+    --vdev 'eth_vhost0,iface=/tmp/sock0,queues=1,client=1' -- -p 0x1 --parse-ptype 1 --config "(0,0,2)"
+
+3. Send packet by testpmd, check vhost-user core will keep wakeup status::
+
+    testpmd>set fwd txonly 
+    testpmd>start
+
+4. Stop and restart testpmd again, check vhost-user core will sleep and wakeup again.
+
+Test Case2:  Wake up vhost-user cores with l3fwd-power sample when multi queues are enabled
+===========================================================================================
+
+1. Launch virtio-user with server mode::
+
+  ./testpmd -l 1-5 -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci --file-prefix=virtio --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=4 -- -i --rxq=4 --txq=4 --rss-ip
+
+2.  Build l3fwd-power sample and launch l3fwd-power with a virtual vhost device::
+
+    ./l3fwd-power -l 9-12 -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci\
+    --log-level=9 --vdev 'eth_vhost0,iface=/tmp/sock0,queues=4,client=1' -- -p 0x1 --parse-ptype 1 \
+    --config "(0,0,9),(0,1,10),(0,2,11),(0,3,12)"
+
+3. Send packet by testpmd, check vhost-user multi-cores will keep wakeup status::
+
+    testpmd>set fwd txonly 
+    testpmd>start
+
+4. Stop and restart testpmd again, check vhost-user cores will sleep and wakeup again.
