+DPDK GRO test plan
+==================
+
+This test plan will cover vdev GRO light/heavy mode test.
+As we need use checksum fwd in this test and make sure ping and iperf packets can reach each side.
+
+Prerequisites

+Test flow
+=========
+
+NIC2(In kernel) -> NIC1(DPDK) -> testpmd(csum fwd) -> Vhost -> Virtio-net
+
+Test Case1: DPDK GRO lightmode test with tcp traffic
+====================================================
+
+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 [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] tso on
+
+2. Bind nic1 to igb_uio, launch vhost-user with testpmd and set flush interval to 1::
+
+    ./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>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 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 \
+       -vnc :10 -daemonize
+
+4. In vm, config the virtio-net device with ip and turn the kernel gro off::
+
+    ifconfig [ens3] 1.1.1.2 up  # [ens3] is the name of virtio-net
+    ethtool -K [ens3] gro off
+
+5. Start iperf test, run iperf server at vm side and iperf client at host side, check throughput in log::
+
+    Host side :  ip netns exec ns1 iperf -c 1.1.1.2 -i 1 -t 60 -m -P 1
+    VM side:     iperf -s
+
+Test Case2: DPDK GRO heavymode test with tcp traffic
+====================================================
+
+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 [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] tso on
+
+2. Bind nic1 to igb_uio, launch vhost-user with testpmd and set flush interval to 2::
+
+    ./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>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 2
+    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 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 \

+       -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 \
+       -vnc :10 -daemonize
+
+4. In vm, config the virtio-net device with ip and turn the kernel gro off::
+
+    ifconfig [ens3] 1.1.1.2 up  # [ens3] is the name of virtio-net
+    ethtool -K [ens3] gro off
+
+5. Start iperf test, run iperf server at vm side and iperf client at host side, check throughput in log::
+
+    Host side :  ip netns exec ns1 iperf -c 1.1.1.2 -i 1 -t 60 -m -P 1
