Subject: [dpdk-dev] [PATCH v3 4/9] sched: update grinder credit and pipe config function
Date: Wed, 16 Sep 2020 17:43:48 +0100
Message-ID: <1600274633-371993-5-git-send-email-savinay.dharmappa@intel.com> (raw)
In-Reply-To: <1600274633-371993-1-git-send-email-savinay.dharmappa@intel.com>

Credits are updated by fetching subport profile parameters from
subport profile table. Similarly subport best effort tc is
calculated in pipe config.
