> Subject: [PATCH v6 0/8] Enable dynamic config of subport bandwidth
>
> 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 patch series implements 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 api and
> data structures defined for port and subport level, new APIs for
> adding subport level bandwidth profiles that can be used in runtime
