+vhost/virtio pvp zero-copy test plan
+====================================
+
+Description
+===========
+
+Vhost dequeue zero-copy is a performance optimization for vhost, so the test case is focused on the performance check.
+As when packet size is 1518B, 10G nic could be the performance bottleneck, so we use 40G traffic genarator and 40G nic for pvp zero-copy test.
+Highlight that vhost zero copy mbufs should be consumed as soon as possible, so don't start send packets at vhost side before VM and virtio-pmd launched.
+
+Test flow
+=========
+
+TG --> NIC --> Vhost --> Virtio--> Vhost --> NIC --> TG
+
+Test Case 1: pvp zero-copy test with different packet sizes
+===========================================================
+
+1. Bind one 40G port to igb_uio, then launch testpmd by below command::
+
+ rm -rf vhost-net*
+ ./testpmd -c 0xe -n 4 --socket-mem 1024,1024 \
+ --vdev 'eth_vhost0,iface=vhost-net,queues=1,dequeue-zero-copy=1' -- \
+ -i --nb-cores=1 --txd=1024 --rxd=1024 --txfreet=992
+ testpmd>set fwd mac
+
+2. Launch VM with mrg_rxbuf feature on, note that qemu_version need > qemu_2.10 for support adjusting parameter rx_queue_size::
+
+ qemu-system-x86_64 -name vm1 \
+ -cpu host -enable-kvm -m 4096 -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc \
+ -smp cores=5,sockets=1 -drive file=/home/osimg/ubuntu16.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:127.0.0.1:6002-:22 \
+ -chardev socket,id=char0,path=./vhost-net \
+ -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
+ -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,rx_queue_size=1024,tx_queue_size=1024 \
+ -vnc :10
+
+3. On VM, bind virtio net to igb_uio and run testpmd::
+
+ ./dpdk-devbind.py --bind=igb_uio xx:xx.x
+ ./testpmd -c 0x3 -n 4 -- -i --nb-cores=1 --txd=1024 --rxd=1024
+ testpmd>set fwd mac
+ testpmd>start
+
+4. Start testpmd at host side after VM and virtio-pmd launched::
+
+ testpmd>start
+
+5. Send packets by packet generator with different packet sizes (64,128,256,512,1024,1518), show throughput with below command::
+
+ testpmd>show port stats all
+
+Test Case 2: pvp zero-copy test with 2 queues
+=============================================
+
+1. Bind one 40G port to igb_uio, then launch testpmd by below command::
+
+ rm -rf vhost-net*
+ ./testpmd -l 2-4 -n 4 --socket-mem 1024,1024 \
+ --vdev 'eth_vhost0,iface=vhost-net,queues=2,dequeue-zero-copy=1' -- \
+ -i --nb-cores=2 --rxq=2 --txq=2 --txd=1024 --rxd=1024 --txfreet=992
+ testpmd>set fwd mac
+
+2. Launch VM with vectors=2*queue_num+2 and mrg_rxbuf/mq feature on, note that qemu_version need > qemu_2.10 for support adjusting parameter rx_queue_size::
+
+ qemu-system-x86_64 -name vm1 \
+ -cpu host -enable-kvm -m 4096 -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc \
+ -smp cores=5,sockets=1 -drive file=/home/osimg/ubuntu16.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:127.0.0.1:6002-:22 \
+ -chardev socket,id=char0,path=./vhost-net \
+ -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=2 \
+ -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,mq=on,vectors=8,rx_queue_size=1024,tx_queue_size=1024 \
+ -vnc :10
+
+3. On VM, bind vdev to igb_uio and run testpmd::
+
+ ./usertools/dpdk-devbind.py --bind=igb_uio xx:xx.x
+ ./testpmd -c 0x07 -n 4 -- -i \
+ --rxq=2 --txq=2 --txd=1024 --rxd=1024 --nb-cores=2
+ testpmd>set fwd mac
+ testpmd>start
+
+4. Start testpmd at host side after VM and virtio-pmd launched::
+
+ testpmd>start
+
+5. Send packets by packet generator with different packet sizes (64,128,256,512,1024,1518), show throughput with below command::
+
+ testpmd>show port stats all
+
+6. Check each queue's rx/tx packet numbers at vhost side::
+
+ testpmd>stop
+
+Test Case 3: pvp zero-copy test with driver unload test
