verify the packets can be received by one VF and can be forward to another VF correctly.
+
+Test Case 2: VF reset test
+==============================================
+
+1. got the pci device id of DUT, for example,
+
+./dpdk_nic_bind.py --st
+
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+
+2. create 3 VFs from 1 PF,
+
+echo 3 > /sys/bus/pci/devices/0000\:81\:00.0/sriov_numvfs
+./dpdk_nic_bind.py --st
+
+0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=igb_uio
+0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=igb_uio

+0000:81:02.1 'XL710/X710 Virtual Function' unused=
+0000:81:02.2 'XL710/X710 Virtual Function' unused=
+
+3. detach VFs from the host, bind them to pci-stub driver,
+
+virsh nodedev-detach pci_0000_81_02_0;
+virsh nodedev-detach pci_0000_81_02_1;
+virsh nodedev-detach pci_0000_81_02_2;

+0000:81:02.2 'XL710/X710 Virtual Function' if= drv=pci-stub unused=igb_uio
+
+4. passthrough VFs 81:02.0 & 81:02.1 to vm0, passthrough VF 81:02.2 to vm1, start vm0 & vm1
+
+/usr/bin/qemu-system-x86_64 -name vm0 -enable-kvm \
+-cpu host -smp 4 -m 2048 -drive file=/home/image/sriov-fc20-1.img -vnc :1 \

+-device pci-assign,host=81:02.2,id=pt_0 \
+
+5. login vm0, got VFs pci device id in vm0, assume they are 00:06.0 & 00:07.0, bind them to igb_uio driver,
+and then start testpmd, set it in mac forward mode,
+
+./tools/dpdk_nic_bind.py --bind=igb_uio 00:06.0 00:07.0
+./x86_64-native-linuxapp-gcc/app/testpmd -c 0x0f -n 4 -w 00:06.0 -w 00:07.0 -- -i --portmask=0x3 --txqflags=0
+
+testpmd> set fwd mac
+testpmd> start
+
+on tester, use scapy, sending packets to vf0 in vm0 in infinite loop.
+
+6. login vm1, got VF pci device id in vm1, assume it is 00:06.0, bind them to igb_uio driver, start testpmd,
+
+./tools/dpdk_nic_bind.py --bind=igb_uio 00:06.0
+./x86_64-native-linuxapp-gcc/app/testpmd -c 0x0f -n 4 -w 00:06.0 -- -i --portmask=0x1 --txqflags=0
+
+in testpmd, run vf port stop/start 1000 times to trigger vf reset 1000 times,
+
+testpmd> port stop all
+testpmd> port start all
+
+7. on tester, kill scapy to stop sending packets to vf0 in vm0, then check the following stats of
+vf0 and vf1 in vm0 to make sure it is correct,
+
+vf0_stats, RX-packets != 0, RX-errors == 0
+vf1_stats, TX-packets != 0, TX-errors == 0
+vf0-RX-packets == vf1-TX-packets

Hi Yulong,
Could you add some basic information in commit log, that will help us to
known what's in the patch.
And for email subject, better follow our format " module name : what
happened".
