+The support of VLAN offload features by VF device consists in:
+
+- the filtering of received VLAN packets
+- VLAN header stripping by hardware in received [VLAN] packets
+- VLAN header insertion by hardware in transmitted packets
+
+Prerequisites
+=============
+1. Create VF device from PF devices.
+	./dpdk_nic_bind.py --st
+	0000:87:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+	0000:87:00.1 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f1 drv=i40e unused=
+
+    echo 1 > /sys/bus/pci/devices/0000\:87\:00.0/sriov_numvfs
+	echo 1 > /sys/bus/pci/devices/0000\:87\:00.1/sriov_numvfs
+
+    ./dpdk_nic_bind.py --st
+
+    0000:87:00.0 'Ethernet Controller X710 for 10GbE SFP+' if=ens259f0 drv=i40e unused=
+    0000:87:02.0 'XL710/X710 Virtual Function' unused=
+    0000:87:0a.0 'XL710/X710 Virtual Function' unused=
+
+2. 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 0000:87:02.0 > /sys/bus/pci/devices/0000:87:02.0/driver/unbind
+	echo 0000:87:02.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+	echo "8086 154c" > /sys/bus/pci/drivers/pci-stub/new_id
+	echo 0000:87:0a.0 > /sys/bus/pci/devices/0000:87:0a.0/driver/unbind
+	echo 0000:87:0a.0 > /sys/bus/pci/drivers/pci-stub/bind
+
+3. Passthrough VFs 87:02.0 & 87:02.1 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=87:02.0,id=pt_0 \
+	-device pci-assign,host=87:0a.0,id=pt_1
+
+4. Login vm0 and them bind VF devices to igb_uio driver.
+
+	./tools/dpdk_nic_bind.py --bind=igb_uio 00:04.0 00:05.0
+
+5. Start testpmd, set it in rxonly mode and enable verbose output
+	testpmd -c 0x0f -n 4 -w 00:04.0 -w 00:05.0 -- -i --portmask=0x3 --txqflags=0
+	testpmd> set fwd rxonly
+	testpmd> set verbose 1
+	testpmd> start
+
+Test Case 1: Add port based vlan on VF
+======================================
+Linux network configration tool only set pvid on VF devices.
+
+1. Add pvid on VF0 from PF device
+	ip link set $PF_INTF vf 0 vlan 2
+
+2. Send packet with same vlan id and check VF can receive
+
+3. Send packet without vlan and check VF can't receive
+
+4. Send packet with wrong and check Vf can't receive
+
+5. Check pf device show correct pvid setting
+	ip link show ens259f0
+	...
+    vf 0 MAC 00:00:00:00:00:00, vlan 1, spoof checking on, link-state auto
+
+Test Case 2: Remove port based vlan on VF
+=========================================
+1. Remove added vlan from PF device
+	ip link set $PF_INTF vf 0 vlan 0
+
+2. Restart testpmd and send packet without vlan and check VF can receive
+
+3. Set packet with vlan id 0 and check VF can receive
+
+4. Set packet with random id 1-4095 and check VF can't receive
+
+Test Case 3: VF port based vlan tx
+==================================
+1. Add pvid on VF0 from PF device
+	ip link set $PF_INTF vf 0 vlan 2
+
+2. Start testpmd with mac forward mode
+	testpmd> set fwd mac
+	testpmd> start
+
+3. Send packet from tester port1 and check packet recevied by tester port0
+	Check port1 recevied packet with configured vlan 2
+
+Test Case 3: VF tagged vlan tx
+===============================
+1. Start testpmd with full-featured tx code path and with mac forward mode
+	testpmd -c f -n 3 -- -i --txqflags=0x0
+	testpmd> set fwd mac
+	testpmd> start
+
+2. Add tx vlan offload on VF0, take care the first param is port
+	testpmd> tx_vlan 0 1
+
+3. Send packet from tester port1 and check packet recevied by tester port0
+	Check port- recevied packet with configured vlan 1
+
+4. rerun with step2-3 with random vlan and max vlan 4095
+
+Test case4: VF tagged vlan rx
+=============================
+1. Make sure port based vlan disabled on VF0 and VF1
+2. Start testpmd with rxonly mode
+	testpmd> set fwd rxonly
+	testpmd> set verbose 1
+	testpmd> start
+
+3. Send packet without vlan and check packet received
+
+4. Send packet with vlan 0 and check packet received
+
+5. Add vlan on VF0 from VF driver
+	testpmd> rx_vlan add 1 0
+
+6. Send packet with vlan0/1 and check packet received
+
+7. rerun with step5-6 with random vlan and max vlan 4095
+
+8. Remove vlan on VF0
+	rx_vlan rm 1 0
+
+9. Send packet with vlan 0 and check packet received
+
+10. Send packet without vlan and check packet received
+
+11. Send packe with vlan 1 and check packet can't recevied
+
+Test case5: VF Vlan strip test
+==============================
+1. Start testpmd with mac forward mode
+	testpmd> set fwd mac
+	testpmd> set verbose 1
+	testpmd> start
+
+2. Add tagged vlan 1 on VF0
+	testpmd> rx_vlan add 1 0
+
+3. Disable VF0 vlan strip and sniff packet on tester port1
+	testpmd> vlan set strip off 0
+
+4. set packet from tester port0 with vlan 1 and check sniffed packet has vlan
+
+5. enable vlan strip on VF0 and sniff packet on tester port1
+	testpmd> vlan set strip on 0
+
+6. send packet from tester port0 with vlan 1 and check sniffed packet without vlan
+
+7. send packet from tester port0 with vlan 0 and check sniffed packet without vlan
+
+8. rerun with step 2-8 with random vlan and max vlan 4095
