Subject: [dpdk-dev] [PATCH v3 1/7] app/bbdev: add explicit ut for latency vs validation
Date: Tue, 18 Aug 2020 17:05:51 -0700 [thread overview]
Message-ID: <1597795557-39612-2-git-send-email-nicolas.chautru@intel.com> (raw)
In-Reply-To: <1597795557-39612-1-git-send-email-nicolas.chautru@intel.com>
Adding explicit different ut when testing for validation
or latency (early termination enabled or not).
