Subject: [dpdk-dev] [PATCH v1 4/4] sched: add dynamic config of subport bandwidth profile
Date: Wed, 2 Sep 2020 09:56:46 +0100 [thread overview]
Message-ID: <1599037006-3931-4-git-send-email-savinay.dharmappa@intel.com> (raw)
In-Reply-To: <1599037006-3931-1-git-send-email-savinay.dharmappa@intel.com>
This patch modifies the way credits are updated. Credits
are updated by fetching parameters from subport profile
table.
