Subject: [dpdk-dev] [PATCH v5 1/7] app/bbdev: add explicit ut for latency vs validation
Date: Fri, 23 Oct 2020 16:42:55 -0700
Message-ID: <1603496581-35966-2-git-send-email-nicolas.chautru@intel.com> (raw)
In-Reply-To: <1603496581-35966-1-git-send-email-nicolas.chautru@intel.com>

Adding explicit different ut when testing for validation
or latency (early termination enabled or not).
