> +=================================
> +1. This example with two packet flows configuration using different
> +ports
> but sharing the same core for QoS scheduler is given below::
>
> - ./qos_sched -l 1,2,6,7 -n 4 -- --pfc "3,2,2,6,7" --pfc "1,0,2,6,7" --
> cfg ../profile.cfg
> -
> -2. Set flows to port 3 and port 1 with different vlan ID.
> - Each Rx flow is shaping to 1/4096 of Tx flow.
> - Set flows with different Destination IP address (0.0.X.0),
> - such as 100.0.1.0-100.0.4.0, which represent different tc.
> - Check the Rx/Tx Bps too.
