+DPDK GRO lib test plan
+======================
+
+Generic Receive Offload (GRO) is a widely used SW-based offloading
+technique to reduce per-packet processing overheads. By reassembling
+small packets into larger ones, GRO enables applications to process
+fewer large packets directly, thus reducing the number of packets to
+be processed. To benefit DPDK-based applications, like Open vSwitch,
+DPDK also provides own GRO implementation. In DPDK, GRO is implemented
+as a standalone library. Applications explicitly use the GRO library to
+reassemble packets.
+
+In the GRO library, there are many GRO types which are defined by packet
+types. One GRO type is in charge of process one kind of packets. For
+example, TCP/IPv4 GRO processes TCP/IPv4 packets.
+
+Each GRO type has a reassembly function, which defines own algorithm and
+table structure to reassemble packets. We assign input packets to the
+corresponding GRO functions by MBUF->packet_type.
+
+The GRO library doesn't check if input packets have correct checksums and
+doesn't re-calculate checksums for merged packets. The GRO library
+assumes the packets are complete (i.e., MF==0 && frag_off==0), when IP
+fragmentation is possible (i.e., DF==0). Additionally, it complies RFC
+6864 to process the IPv4 ID field.
+
+Currently, the GRO library provides GRO supports for TCP/IPv4 packets and
+VxLAN packets which contain an outer IPv4 header and an inner TCP/IPv4
+packet.
+
+This test plan includes dpdk gro lib test with TCP/IPv4 traffic and VxLAN traffic,
+also cover lightmode and heavymode test.

+Test flow
+=========
+
+NIC2(In kernel) -> NIC1(DPDK) -> testpmd(csum fwd) -> Vhost -> Virtio-net
+
+Test Case1: DPDK GRO lightmode test with tcp/ipv4 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 \

+       -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
