Subject: [dpdk-dev] [RFC PATCH 1/2] sched: add dynamic config of subport bandwidth profile
Date: Wed, 15 Jul 2020 19:27:56 +0100
Message-ID: <1594837677-313175-2-git-send-email-savinay.dharmappa@intel.com> (raw)
In-Reply-To: <1594837677-313175-1-git-send-email-savinay.dharmappa@intel.com>

This patch modifies the subport level data structures
and add new API to allow dynamic configuration of the
subport bandwidth profile.
