+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

+
+3. Set up vm with virto device and using kernel virtio-net driver::
+
+ taskset -c 31 /home/qemu-install/qemu-4.2.1/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 \

+ -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=2 \

+ -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 case5::
+
+ 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
