+Support of VLAN Offload Features by Poll Mode Drivers
+=====================================================
+
+The support of VLAN offload features by Poll Mode Drivers 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.
+
+The filtering of VLAN packets is automatically enabled by the ``testpmd``
+application for each port.
+By default, the VLAN filter of each port is empty and all received VLAN packets
+are dropped by the hardware.
+To enable the receipt of VLAN packets tagged with the VLAN tag identifier
+``vlan_id`` on the port ``port_id``, the following command of the ``testpmd``
+application must be used::
+
+  rx_vlan add vlan_id port_id
+
+In the same way, the insertion of a VLAN header with the VLAN tag identifier
+``vlan_id`` in packets sent on the port ``port_id`` can be enabled with the
+following command of the ``testpmd`` application::
+
+  tx_vlan set vlan_id port_id
+
+
+The transmission of VLAN packets is done with the ``start tx_first`` command
+of the ``testpmd`` application that arranges to first send a burst of packets
+on all configured ports before starting the ``rxonly`` packet forwarding mode
+that has been previously selected.
+
+
+Prerequisites
+=============
+Assuming that ports ``0`` and ``1`` are connected to a traffic generator's port
+``A`` and ``B``. Launch the ``testpmd`` with the following arguments::
+  ./build/app/testpmd -cffffff -n 3 -- -i 
+The -n command is used to select the number of memory channels. 
+It should match the number of memory channels on that setup.
+Set the verbose level to 1 to display informations for each received packet::
+  testpmd> set verbose 1
+
+Test Case: enable filter on and set rx_vlan
+===========================================
+Vlan set filter on 0
+Vlan rx_vlan add %vid 0
+1 Send packets with vid=%vid ,check packet can be received by tester and vid=%vid
+2 Send packets without vlan tag ,and check packet can received by tester.
+3 Send packets with other vid,and check packet cannot received by tester.
+
+Repeat step above and %vid in range [1, random vid, max vid]
+
+Take 1 for example:: 
+  testpmd> set fwd mac
+  testpmd> vlan set filter on 0
+  testpmd> rx_vlan add %vid 0
+  testpmd> start
+Configure the traffic generator to send VLAN packets with the Tag Identifier
+ ``%vid`` and send 1 packet on port ``A``.
+Verify that the VLAN packet was correctly received on port ``B`` with VLAN tag ``%vid``.
+
+Test Case: enable filter on and  rx_vlan rm
+===============================================
+Vlan set filter on 0
+rx_vlan rm %vid 0
+1 Send packets with vid=%vid ,and check packet cannot be received by tester.
+2 Send packets without vlan tag ,and check packet can be received by tester.
+3 Send packets with other vid,and check packet cannot be received by tester.
+But Fortville nic , nic will add vlan=0 as default, so all packets will be received by tester.
+
+Repeat step above and %vid in range [1, random vid, max vid]
+
+Take 1 for example:
+Disable the receipt of VLAN packets with Tag Identifier ``%vid`` on port 0::
+  testpmd> vlan set filter on 0
+  testpmd> rx_vlan rm %vid 0
+  testpmd> start
+Send VLAN packets with the Tag Identifier ``%vid`` check that no packet is received
+on port ``B``, meaning that VLAN packets are now dropped on port 0::
+Verify that no packet was received on port ``B``.
+
+Test Case: disable vlan filter 
+===============================================
+Vlan set filter off 0
+1 Send packets with vid=%vid ,check packet can be received by tester and vid=%vid
+2 Send packets without vlan tag ,and check packet can be received by tester.
+3 Send packets with other vid,and check packet can be received by tester and vid=other vid.
+
+Repeat step above and %vid in range [1, random vid, max vid]
+
+Test Case: rx_vlan add/rm
+===============================================
+vlan set filter on 0
+rx_vlan add %vid 0
+rx_vlan add %vid+1 0
+rx_vlan add %vid+2 0
+rx_vlan add %vid+3 0
+Send packets with vid, vid+1, vid+2, vid+3 ,check packet can be received by tester and vlan id = vid, vid+1, vid+2, vid+3
+rx_vlan rm %vid 0
+rx_vlan rm %vid+1 0
+rx_vlan rm %vid+2 0
+rx_vlan rm %vid+3 0
+rx_vlan rm %vid+4 0
+Send packets with vid, vid+1, vid+2, vid+3 ,check packet cannot be received by tester.
+Repeat steps above 10 times.
+
+Repeat step above and %vid in range [1, random vid, max vid-4]
+
+
+Test Case: vlan strip on
+===============================================
+vlan set filter off 0
+vlan set strip on 0
+1 Send packets with vid=%vid ,and check packet without vlan can be received by tester.
+2 Send packets without vlan tag ,and check packet without vlan can be received by tester.
+3 Send packets with other vid, check packet without vlan can be received by tester.
+Repeat step above and %vid in range [1, random vid, max vid]
+
+Test Case: vlan strip off
+===============================================
+vlan set filter off 0
+vlan set strip off 0
+1 Send packets with vid=%vid ,check packet can be received by tester and vid=%vid
+2 Send packets without vlan tag ,and check packet can be received by tester.
+3 Send packets with other vid,and check packet can be received by tester and vid=other vid.
+
+Repeat step above and %vid in range [1, random vid, max vid]
+
+Test Case: Enable VLAN header insertion in transmitted packets
+==============================================================
+vlan set filter off 0
+vlan set strip off 0
+tx_vlan set %vid 0
+Send packets without vlan tag ,and check packet can be received by tester and vid=%vid.
+Repeat step above and %vid in range [1, random vid, max vid]
+
+::
+  testpmd> vlan set filter off 0
+  testpmd> vlan set strip off 0
+  testpmd> tx_vlan set %vid 0
+Send packet without vlan.
+Verify that the packet is correctly received on the traffic generator side
+(with VLAN Tag Identifier ``%vid``)
