> +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.

> +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::

> +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)::

> + the expected output traffic should be marked as shown in the following
