> DPDK sched library allows runtime configuration of the pipe profiles to the
> pipes of the subport once scheduler hierarchy is constructed. However, to
> change the subport level bandwidth, existing hierarchy needs to be
> dismantled and whole process of building hierarchy under subport nodes
> needs to be repeated which might result in router downtime. Furthermore,
> due to lack of dynamic configuration of the subport bandwidth profile
> configuration (shaper and Traffic class rates), the user application is unable
> to dynamically re-distribute the excess-bandwidth of one subport among
> other subports in the scheduler hierarchy. Therefore, it is also not possible to
> adjust the subport bandwidth profile in sync with dynamic changes in pipe
> profiles of subscribers who want to consume higher bandwidth
> opportunistically.
> 
> This RFC proposes dynamic configuration of the subport bandwidth profile to
> overcome the runtime situation when group of subscribers are not using the
> allotted bandwidth and dynamic bandwidth re-distribution is needed the
> without making any structural changes in the hierarchy.
> 
> The implementation work includes refactoring the existing data structures
> defined for port and subport level, new APIs for adding subport level
> bandwidth profiles that can be used in runtime which causes API/ABI change.
> Therefore, deprecation notice will be sent out soon.
