-# AF using CBQ for a single interface eth0 
-# 4 AF classes using GRED and one BE using RED
-# Things you might want to change:
-#      - the device bandwidth (set at 10Mbits)
-#      - the bandwidth allocated for each AF class and the BE class    
-#      - the drop probability associated with each AF virtual queue
-#
-# AF DSCP values used (based on AF draft 04)
-# -----------------------------------------
-# AF DSCP values
-# AF1 1. 0x0a 2. 0x0c 3. 0x0e
-# AF2 1. 0x12 2. 0x14 3. 0x16
-# AF3 1. 0x1a 2. 0x1c 3. 0x1e
-# AF4 1. 0x22 2. 0x24 3. 0x26

-# A simple DSCP-class relationship formula used to generate

-#  if you use GRIO buffer sharing, then GRED priority is set as follows:
