-* sched: To allow dynamic configuration of the subport bandwidth profile,
-  changes will be made to data structures ``rte_sched_subport_params``,
-  ``rte_sched_port_params`` and new data structure, API functions will be
-  defined in ``rte_sched.h``. These changes are aligned as suggested in the
-  RFC https://mails.dpdk.org/archives/dev/2020-July/175161.html
-
 * metrics: The function ``rte_metrics_init`` will have a non-void return
   in order to notify errors instead of calling ``rte_exit``.
