Subject: [dpdk-dev] [PATCH v2 11/15] examples/eventdev: add single stage pipeline worker
Date: Wed, 10 Jan 2018 16:40:09 +0530	[thread overview]
Message-ID: <20180110111013.14644-11-pbhagavatula@caviumnetworks.com> (raw)
In-Reply-To: <20180110111013.14644-1-pbhagavatula@caviumnetworks.com>

Add optimized eventdev pipeline when ethdev supports thread safe Tx
and number of configured stages is one.
