+Test Case 1: create 2VFs from 2 kernel PFs, passthrough 2VFs to 1VM, using dpdk vf in VM, do packet rx tx 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 2 VFs from 2 PFs,
+
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.0/sriov_numvfs
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.1/sriov_numvfs
+./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=
+0000:81:02.0 'XL710/X710 Virtual Function' unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' unused=
+
+3. detach VFs from the host, bind them to pci-stub driver,
+
+/sbin/modprobe pci-stub
+
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:02.0 > /sys/bus/pci/devices/0000:08:02.0/driver/unbind
+echo 0000:81:02.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:0a.0 > /sys/bus/pci/devices/0000:08:0a.0/driver/unbind
+echo 0000:81:0a.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+or using the following more easy way,
+
+virsh nodedev-detach pci_0000_81_02_0;
+virsh nodedev-detach pci_0000_81_0a_0;
+
+./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=
+0000:81:02.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+
+it can be seen that VFs 81:02.0 & 81:0a.0 's drv is pci-stub.
+
+4. passthrough VFs 81:02.0 & 81:0a.0 to vm0, and start vm0,
+
+/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=81:02.0,id=pt_0 \
+-device pci-assign,host=81:0a.0,id=pt_1
+
+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
+
+6. get mac address of one VF and use it as dest mac, using scapy to send 2000 ethernet frames from tester,
+verify the frames can be received by one VF and can be forward to another VF correctly.
+

+Test Case 1: create 2VFs from 2 kernel PFs, passthrough 2VFs to 1VM, using dpdk vf in VM, do packet rx tx test.
+=======================================================================
+======================================
[QIAN] the title is a little long, could you change it to VF_packet_IO_kernel_PF
+
+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 2 VFs from 2 PFs,
+
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.0/sriov_numvfs
+echo 1 > /sys/bus/pci/devices/0000\:81\:00.1/sriov_numvfs
+./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=
+0000:81:02.0 'XL710/X710 Virtual Function' unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' unused=
+
+3. detach VFs from the host, bind them to pci-stub driver,
+
+/sbin/modprobe pci-stub
+
[QIAN] As to the VF device ID, better to give a way of how to know the VF device ID. We need get it from "lspci -nn|grep Eth", 154C is also got from there.
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:02.0 > /sys/bus/pci/devices/0000:08:02.0/driver/unbind
+echo 0000:81:02.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+echo 0000:81:0a.0 > /sys/bus/pci/devices/0000:08:0a.0/driver/unbind
+echo 0000:81:0a.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+or using the following more easy way,
+
+virsh nodedev-detach pci_0000_81_02_0; virsh nodedev-detach
+pci_0000_81_0a_0;
+
+./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=
+0000:81:02.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+0000:81:0a.0 'XL710/X710 Virtual Function' if= drv=pci-stub unused=
+
+it can be seen that VFs 81:02.0 & 81:0a.0 's drv is pci-stub.
+
+4. passthrough VFs 81:02.0 & 81:0a.0 to vm0, and start vm0,
+
+/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=81:02.0,id=pt_0 \ -device
+pci-assign,host=81:0a.0,id=pt_1
+
+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
+
+6. get mac address of one VF and use it as dest mac, using scapy to
+send 2000 ethernet frames from tester, verify the frames can be received by one VF and can be forward to another VF correctly.
