+Test Case 2: VF_packet_IO_dpdk_PF_dpdk_VF
+===========================================
+
+1. Got the pci device id of DUT, for example::
+
+      ./usertools/dpdk-devbind.py -s
+
+      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. bind pf to igb_uio and Create 2 VFs from 2 PFs::
+
+      ./usertools/dpdk-devbind.py --bind=igb_uio 0000:81:00.0 0000:81:00.1
+      echo 1 > /sys/bus/pci/devices/0000\:81\:00.0/max_vfs
+      echo 1 > /sys/bus/pci/devices/0000\:81\:00.1/max_vfs
+
+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 0000:81:0a.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+   or using the following more easy way::

+      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.

+
+5. 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
+
+6. 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::
+
+      ./usertools/dpdk-devbind.py --bind=igb_uio 00:06.0 00:07.0

+
+      testpmd> set fwd mac
+      testpmd> start
+
+7. 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.

Re: [dts] [PATCH V2 2/2] test_plan/vf packet rxtx: add dpdk pf + dpdk vf test scenario

[Liu, Yong]

Meijuan,
Please just use one line for header and test case name should be more 
meaningful like "dpdk control PF and VF reset".

Thanks,
Marvin
