+QoS Metering Tests
+==================
+The QoS meter sample application is an example that demonstrates the use of
+DPDK to provide QoS marking and metering, as defined by RFC2697 for Single
+Rate Three Color Marker (srTCM) and RFC 2698 for Two Rate Three Color
+Marker (trTCM) algorithm.
+
+The detailed description of the application items and mode can be found in
+https://doc.dpdk.org/guides/sample_app_ug/qos_metering.html
+
+Prerequisites
+=============
+The DUT must have two 10G Ethernet ports connected to two ports of IXIA.
+
+Assume two DUT 10G Ethernet ports' pci device id is as the following,
+
+dut_port_0 : "0000:05:00.0"
+dut_port_1 : "0000:05:00.1"
+
+1. Compile DPDK and sample
+
+2. Bind two ports to dpdk igb_uio driver::
+
+    ./usertools/dpdk-devbind.py -b igb_uio 05:00.0 05:00.1
+
+3. The default metering mode is::
+
+    APP_MODE_SRTCM_COLOR_BLIND
+
+Test Case: srTCM blind
+======================
+1. The application is constrained to use a single core in the EAL core mask
+   and 2 ports only in the application port mask (first port from the port
+   mask is used for RX and the other port in the core mask is used for TX)::
+
+    ./build/qos_meter -c 1 -n 4 -- -p 0x3
+
+2. Assuming the input traffic is generated at line rate and all packets
+   are 64 bytes Ethernet frames (IPv4 packet size of 46 bytes) and green,
+   the expected output traffic should be marked as shown in the following
+   table:
+
+   +-------------+--------------+---------------+------------+
+   |     Mode    | Green (Mpps) | Yellow (Mpps) | Red (Mpps) |
+   +-------------+--------------+---------------+------------+
+   | srTCM blind | 1            | 1             | 12.88      |
+   +-------------+------------------------------+------------+
+   | srTCM color | 1            | 1             | 12.88      |
+   +-------------+------------------------------+------------+
+   | trTCM blind | 1            | 0.5           | 13.38      |
+   +-------------+------------------------------+------------+
+   | trTCM color | 1            | 0.5           | 13.38      |
+   +-------------+------------------------------+------------+
+   |     FWD     | 14.88        | 0             | 0          |
+   +-------------+------------------------------+------------+
+
+3. Use the default setting, the packets are 64 bytes Ethernet frames,
+   and the metering mode is srTCM blind.
+   The green packets are dropped.
+   So the valid frames received on the peer IXIA port is 13.88(Mpps).
