[v2]
Minor changes on the code format and value assignment.
[v1]
Updated vmdq test suite, and it works for both FVL and Niantic. The major changes are as below:
1. Support FVL 4x10g, 2x10g, 2x40g.
2. Update the traffic to make the MAC address and VLAN id changes together. Then the packet loss is 0 at low traffic.
3. Set the max pools number for major NICs: FVL 40G, 10G, Niantic, 1G.
4. Update the core config.

+
+=========================================================================
+Support of RX/TX Packet Filtering using VMDQ Features of 40G&10G&1G NIC
+=========================================================================
+
+The 1G, 10G 82599 and 40G FVL Network Interface Card (NIC), supports a number of packet
+filtering functions which can be used to distribute incoming packets into a
+number of reception (RX) queues. VMDQ is a filtering
+functions which operate on VLAN-tagged packets to distribute those packets
+among up to 512 RX queues.
+
+The feature itself works by:
+
+- splitting the incoming packets up into different "pools" - each with its own
+ set of RX queues - based upon the MAC address and VLAN ID within the VLAN tag of the packet.
+- assigning each packet to a specific queue within the pool, based upon the
+ user priority field within the VLAN tag and MAC address.
+
+The VMDQ features are enabled in the ``vmdq`` example application
+contained in the Intel DPDK, and this application should be used to validate
+the feature.
+
+Prerequisites
+=============
+- All tests assume a linuxapp setup.
+- The port ids of the two 10G or 40G ports to be used for the testing are specified
+ in the commandline. it use a portmask.
+- The Intel DPDK is compiled for the appropriate target type in each case, and
+ the VMDQ example application is compiled and linked with that DPDK
+ instance
+- Two ports are connected to the test system, one to be used for packet
+ reception, the other for transmission
+- The traffic generator being used is configured to send to the application RX
+ port a stream of packets with VLAN tags, where the VLAN IDs increment from 0
+ to the pools numbers(e.g: for FVL spirit, it's 63, inclusive) as well as the MAC address from
+ 52:54:00:12:[port_index]:00 to 52:54:00:12:[port_index]:3e and the VLAN user priority field increments from 0 to 7
+ (inclusive) for each VLAN ID. In our case port_index = 0 or 1.
+
+
+Test Case: Measure VMDQ pools queues
+------------------------------------
+1. Put different number of pools: in the case of 10G 82599 Nic is 64, in the case
+ of FVL spirit is 63,in case of FVL eagle is 34.
+2. Start traffic transmission using approx 10% of line rate.
+3. After a number of seconds, e.g. 15, stop traffic, and ensure no traffic
+ loss (<0.001%) has occurred.
+4. Send a hangup signal (SIGHUP) to the application to have it print out the
+ statistics of how many packets were received per RX queue
+
+Expected Result:
+
+- No packet loss is expected
+- Every RX queue should have received approximately (+/-15%) the same number of
+ incoming packets
+
+Test Case: Measure VMDQ Performance
+-----------------------------------
+
+1. Compile VMDQ example application as in first test above.
+2. Run application using a core mask for the appropriate thread and core
+ settings given in the following list:
+
+ * 1S/1C/1T
+ * 1S/2C/1T
+ * 1S/2C/2T
+ * 1S/4C/1T
+
+3. Measure maximum RFC2544 performance throughput for bi-directional traffic for
+ all standard packet sizes.
+
+Output Format:
+The output format should be as below, or any similar table-type, with figures
+given in mpps:
+
++------------+----------+----------+----------+----------+
+| Frame size | 1S/1C/1T | 1S/2C/1T | 1S/2C/2T | 1S/4C/1T |
++============+==========+==========+==========+==========+
+| 64 | 19.582 | 42.222 | 53.204 | 73.768 |
