  32 ; This file enables the following hierarchical scheduler configuration for each
  33 ; 10GbE output port:
  34 ;       * Single subport (subport 0):
  35 ;               - Subport rate set to 100% of port rate
  36 ;               - Each of the 4 traffic classes has rate set to 100% of port rate
  37 ;       * 4K pipes per subport 0 (pipes 0 .. 4095) with identical configuration:
  38 ;               - Pipe rate set to 1/4K of port rate
  39 ;               - Each of the 4 traffic classes has rate set to 100% of pipe rate
  40 ;               - Within each traffic class, the byte-level WRR weights for the 4 queues
  41 ;         are set to 1:1:1:1
  42 ;
  43 ; For more details, please refer to chapter "Quality of Service (QoS) Framework"
  44 ; of Data Plane Development Kit (DPDK) Programmer's Guide.
