+vhost-user interrupt mode test plan
+===================================
+
+Description
+===========
+
+Vhost-user 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 flow
+=========
+
+Virtio-user --> Vhost-user
+
+Test Case1: Wake up split ring vhost-user core with l3fwd-power sample
+======================================================================
+
+1. Launch virtio-user with server mode::
+
+ ./testpmd -l 7-8 -n 4 --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 --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 split ring 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 --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 --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.
+
+Test Case3: Wake up packed ring vhost-user core with l3fwd-power sample
+=======================================================================
+
+1. Launch virtio-user with server mode::
+
+ ./testpmd -l 7-8 -n 4 --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=1,packed_vq=1 -- -i
+
+2. Build l3fwd-power sample and launch l3fwd-power with a virtual vhost device::
+
+ ./l3fwd-power -l 0-3 -n 4 --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 Case4: Wake up packed ring 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 --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=4,packed_vq=1,mrg_rxbuf=0 -- -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 --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.
+
+Test Case5: Wake up split ring vhost-user cores with l3fwd-power sample when multi queues and cbdma are enabled
+===============================================================================================================
+
+1. Launch virtio-user with server mode::
+
+ ./testpmd -l 1-5 -n 4 --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. Bind 4 cbdma ports to igb_uio driver, then launch l3fwd-power with a virtual vhost device::
+
+ ./l3fwd-power -l 9-12 -n 4 --log-level=9 \
+ --vdev 'eth_vhost0,iface=/tmp/sock0,queues=4,client=1,dmas=[txq0@80:04.0;txq1@80:04.1;txq2@80:04.2;txq3@80:04.3]' -- -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.
