Subject: [dpdk-dev] [PATCH v3 9/9] sched: remove the redundant code
Date: Wed, 16 Sep 2020 17:43:53 +0100 [thread overview]
Message-ID: <1600274633-371993-10-git-send-email-savinay.dharmappa@intel.com> (raw)
In-Reply-To: <1600274633-371993-1-git-send-email-savinay.dharmappa@intel.com>
Remove redundant data structure fields references from
functions and subport level data structures. It also
update the release and deprecation note.

-* 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``.

=======================================================
+* sched: The subport bandwidth configuration parameters such as tb_rate,
+ tc_rate, tc_period etc., are moved from subport level data structure to
+ new a data structure. This allows to configure a subport with different
+ subport bandwidth configuration dynamically.
