Subject: [dpdk-dev] [PATCH v2 06/15] examples/eventdev: add non burst mode generic worker
Date: Wed, 10 Jan 2018 16:40:04 +0530 [thread overview]
Message-ID: <20180110111013.14644-6-pbhagavatula@caviumnetworks.com> (raw)
In-Reply-To: <20180110111013.14644-1-pbhagavatula@caviumnetworks.com>
Currently, worker uses burst dequeue and burst enqueue to forward events.
Add a non burst mode based on the event dev capabilities.
