+==================================================================
+
+Test flow
+=========
+
+NIC2(In kernel) -> NIC1(DPDK) -> testpmd(csum fwd) -> Vhost -> Virtio-net
+
+1. Connect two nic port directly, put nic2 into another namesapce and turn on the tso of this nic port by below cmds::
+
+    ip netns del ns1
+    ip netns add ns1
+    ip link set enp26s0f0 netns ns1       # [enp216s0f0] is the name of nic2
+    ip netns exec ns1 ifconfig enp26s0f0 1.1.1.8 up
+    ip netns exec ns1 ethtool -K enp26s0f0 tso on
+
+2. Bind cbdma port and nic1 to igb_uio, launch vhost-user with testpmd and set flush interval to 1::
+
+    ./dpdk-devbind.py -b igb_uio xx:xx.x
+    ./x86_64-native-linuxapp-gcc/app/testpmd -l 29-30 -n 4 \
+    --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=2,dmas=[txq0@80:04.0;txq1@80:04.1],dmathr=1024' -- -i --txd=1024 --rxd=1024 --txq=2 --rxq=2
+    testpmd>set fwd csum
+    testpmd>stop
+    testpmd>port stop 0
+    testpmd>port stop 1
+    testpmd>csum set tcp hw 0
+    testpmd>csum set ip hw 0
+    testpmd>csum set tcp hw 1
+    testpmd>csum set ip hw 1
+    testpmd>set port 0 gro on
+    testpmd>set gro flush 1
+    testpmd>port start 0
+    testpmd>port start 1
+    testpmd>start
+
+3.  Set up vm with virto device and using kernel virtio-net driver::
+
+    taskset -c 31 /home/qemu-install/qemu-3.0/bin/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 -netdev user,id=yinan,hostfwd=tcp:127.0.0.1:6005-:22 -device e1000,netdev=yinan \
+       -smp cores=1,sockets=1 -drive file=/home/osimg/ubuntu1910.img  \
+       -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,csum=on,gso=on,host_tso4=on,guest_tso4=on,mq=on,vectors=15 \
+       -vnc :10 -daemonize
+
+4. In vm, config the virtio-net device with ip and turn the kernel gro off::
+
+    ifconfig ens4 1.1.1.2 up  # [ens3] is the name of virtio-net
+    ethtool -L ens4 combined 2
+    ethtool -K ens4 gro off
+
+5. Start iperf test, run iperf server at vm side and iperf client at host side, check throughput in log can get better performance than case 1::
+
+    Host side :  taskset -c 35 ip netns exec ns1 iperf -c 1.1.1.2 -i 1 -t 60 -m -P 2
+    VM side:     iperf -s
