+ ip netns add ns1
+ ip link set enp26s0f0 netns ns1 # [enp216s0f0] is the name of nic2

+
+ 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, should be larger than 10Gbits/sec::
+
+ Host side : taskset -c 35 ip netns exec ns1 iperf -c 1.1.1.2 -i 1 -t 60 -m -P 2
