; Compared to config/bng-4ports.cfg, this configuration sets up a BNG with QoS
; functionality. In total, an extra eight cores (four physical cores) are needed
; to run this configuration. Four cores are used for QoS, two cores are assigned
; with the task of classifying upstream packets and two cores are assigned with
; transmitting downstream packets.
