+
+Test Case 1: VF_packet_IO_kernel_PF_dpdk_VF
+==============================================
+
+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
+
+using `lspci -nn|grep -i ethernet` got VF device id, for example "8086 154c",
+
+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 random packets from tester,
+verify the packets can be received by one VF and can be forward to another VF correctly.

One more comment: 
If using kernel Host driver, we need turn on the CRC strip on the VF testpmd, or else there will be 4 bytes missing which will cause the packet truncated when using tcpdump. 

Below is the command to set crc-strip on, we need set it before forwarding methods. 

testpmd>port stop all
testpmd>port config all crc-strip on 
testpmd>port start all



Thanks
Qian
