+Test flow
+=========
+
+NIC2(In kernel) <- NIC1(DPDK) <- testpmd(csum fwd) <- Vhost <- Virtio-net
+
+Test Case1: DPDK GSO test with tcp traffic
+==========================================
+
+1. Connect two nic port directly, put nic2 into another namesapce and turn on the gro of this nic port by below cmds::
+
+ ip netns del ns1
+ ip netns add ns1
+ ip link set [enp216s0f0] netns ns1 # [enp216s0f0] is the name of nic2
+ ip netns exec ns1 ifconfig [enp216s0f0] 1.1.1.8 up
+ ip netns exec ns1 ethtool -K [enp216s0f0] gro on
+
+2. Bind nic1 to igb_uio, launch vhost-user with testpmd::
+
+ ./dpdk-devbind.py -b igb_uio xx:xx.x # xx:xx.x is the pci addr of nic1
+ ./testpmd -l 2-4 -n 4 --socket-mem 1024,1024 --legacy-mem \
+ --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0' -- -i --txd=1024 --rxd=1024
+ testpmd>set fwd csum
+ testpmd>stop
+ testpmd>port stop 0
+ testpmd>csum set tcp hw 0
+ testpmd>csum set ip hw 0
+ testpmd>set port 0 gso on
+ testpmd>set gso segsz 1460
+ testpmd>port start 0
+ testpmd>start
+
+3. Set up vm with virto device and using kernel virtio-net driver::
+
+ taskset -c 13 \
+ 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,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,csum=on,gso=on,host_tso4=on,guest_tso4=on,rx_queue_size=1024,tx_queue_size=1024 -vnc :10 -daemonize
+
+4. In vm, config the virtio-net device with ip::
+
+ ifconfig [ens3] 1.1.1.2 up # [ens3] is the name of virtio-net
+
+5. Start iperf test, run iperf server at host side and iperf client at vm side, check throughput in log::
+
+ Host side : ip netns exec ns1 iperf -s
+ VM side: iperf -c 1.1.1.8 -i 1 -t 60
+
+Test Case2: DPDK GSO test with udp traffic
+==========================================
+
+Similar as Test Case1, all steps are similar except step 5.
+
+5. Start iperf test, run iperf server at host side and iperf client at vm side, check throughput in log::
+
+ Host side : ip netns exec ns1 iperf -s -u
+ VM side: iperf -c 1.1.1.8 -i 1 -t 60 -P 4 -u -b 10G -l 9000
+
+Test Case3: DPDK GSO test with vxlan traffic
+============================================
+
+1. Connect two nic port directly, put nic2 into another namesapce and generate the vxlan device in this name space::
+
+ ip netns del ns1
+ ip netns add ns1
+ ip link set [enp216s0f0] netns ns1 # [enp216s0f0] is the name of nic2
+ ip netns exec ns1 ifconfig [enp216s0f0] 188.0.0.1 up
+ ip netns exec ns1 ip link add vxlan100 type vxlan id 1000 remote 188.0.0.2 local 188.0.0.1 dstport 4789 dev [enp216s0f0]
+ ip netns exec ns1 ifconfig vxlan100 1.1.1.1/24 up
+
+2. Bind nic1 to igb_uio, launch vhost-user with testpmd::
+
+ ./dpdk-devbind.py -b igb_uio xx:xx.x
+ ./testpmd -l 2-4 -n 4 --socket-mem 1024,1024 --legacy-mem \
+ --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0' -- -i --txd=1024 --rxd=1024
+ testpmd>set fwd csum
+ testpmd>stop
+ testpmd>port stop 0
+ testpmd>csum set tcp hw 0
+ testpmd>csum set ip hw 0
+ testpmd>csum set outer-ip hw 0
+ testpmd>csum parse-tunnel on 0
+ testpmd>set port 0 gso on
+ testpmd>set gso segsz 1400
+ testpmd>port start 0
+ testpmd>start
+
+3. Set up vm with virto device and using kernel virtio-net driver::
+
