Subject: [dpdk-dev] [PATCH v1 3/7] app/bbdev: include explict HARQ preloading
Date: Tue, 18 Aug 2020 16:46:23 -0700	[thread overview]
Message-ID: <1597794387-37526-4-git-send-email-nicolas.chautru@intel.com> (raw)
In-Reply-To: <1597794387-37526-1-git-send-email-nicolas.chautru@intel.com>

Run preloading explictly for unit tests. Load each code block
by reusing existing input op then restore for the actual test.
