+In some systems an additional external tag (E-tag) can be present before the
+VLAN. NIC X550 support VLANs in presence of external tags.
+E-tag mode is used for systems where the device adds a tag to identify a
+subsystem (usually a VM) and the near end switch adds a tag indicating the
+destination subsystem.
+
+The support of E-tag features by X550 consists in:
+- the filtering of received E-tag packets
+- E-tag header stripping by VF device in received packets
+- E-tag header insertion by VF device in transmitted packets
+- E-tag forwarding to assigned VF by E-tag id
+
+Prerequisites
+=============
+1. Create 2VF devices from PF device.
+ ./dpdk_nic_bind.py --st
+ 0000:84:00.0 'Device 1563' drv=igb_uio unused=
+ echo 2 > /sys/bus/pci/devices/0000\:84\:00.0/max_vfs
+
+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 1565",
+
+ echo "8086 1565" > /sys/bus/pci/drivers/pci-stub/new_id
+ echo 0000:84:10.0 > /sys/bus/pci/devices/0000:84:10.0/driver/unbind
+ echo 0000:84:10.0 > /sys/bus/pci/drivers/pci-stub/bind
+ echo 0000:84:10.2 > /sys/bus/pci/devices/0000:84:10.2/driver/unbind
+ echo 0000:84:10.2 > /sys/bus/pci/drivers/pci-stub/bind
+
+3. Passthrough VF 84:10.0 & 84:10.2 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=84:10.0,id=pt_0 \
+ -device pci-assign,host=84:10.2,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 host testpmd, set it in rxonly mode and enable verbose output
+ testpmd -c f -n 3 -- -i
+ testpmd> set fwd rxonly
+ testpmd> set verbose 1
+ testpmd> start
+
+6. Start guest testpmd, set it in mac forward mode
+ testpmd -c 0x3 -n 1 -- -i --txqflags=0x0
+ testpmd> set fwd mac
+ testpmd> start
+
+Test Case 1: L2 tunnel filter
+=============================
+Enable E-tag l2 tunnel support means enabling ability of parsing E-tag packet.
+This ability should be enabled before we enable filtering, forwarding,
+offloading for this specific type of tunnel.
+
+ testpmd> port config 0 l2-tunnel E-tag enable
+
+Send 802.1BR packet to PF and VFs, check packet normally recevied.
+ - type=0x893f - length=150 - nb_segs=1 - (outer) L2 type: Unknown
+ - (outer) L3 type: IPV4 - (outer) L4 type: UDP
+
+Test Case 2: E-tag filter
+=========================
+Enable E-tag packet forwarding and add E-tag on VF0, Send 802.1BR packet with
+broardcast mac and check packet only recevied on VF0
+
+ testpmd> E-tag set forwarding on port 0
+ testpmd> E-tag set filter add e-tag-id 1000 dst-pool 0 port 0
+
+Same E-tag forwarding to VF1, Send 802.1BR packet with broardcast mac and
+check packet only recevied on VF1
+
+ testpmd> E-tag set filter add e-tag-id 1000 dst-pool 1 port 0
+
+Same E-tag forwarding to PF0, Send 802.1BR packet with broardcast mac and
+check packet only recevied on PF
+
+ testpmd> E-tag set filter add e-tag-id 1000 dst-pool 2 port 0
+
+Remove E-tag, Send 802.1BR packet with broardcast mac and check packet not
+recevied
+
+ testpmd> E-tag set filter del e-tag-id 1000 port 0
+
+Test Case 3: E-tag insertion
+============================
+Enable E-tag insertion in VF0, send normal packet to VF1 and check forwared
+packet contain E-tag
+
+ testpmd> E-tag set insertion on port-tag-id 1000 port 0 vf 0
+
+Test Case 4: E-tag strip
+=========================
+Enable E-tag strip on PF, Send 802.1BR packet to VF and check forwarded packet
+without E-tag.
+
+ testpmd> E-tag set stripping on port 0
+
+Disable E-tag strip on PF, Send 802.1BR packet and check forwarded packet with
+E-tag.
+
+ testpmd> E-tag set stripping off port 0
