Subject: [dpdk-dev] [PATCH v2 07/15] examples/eventdev: modify work cycles
Date: Wed, 10 Jan 2018 16:40:05 +0530 [thread overview]
Message-ID: <20180110111013.14644-7-pbhagavatula@caviumnetworks.com> (raw)
In-Reply-To: <20180110111013.14644-1-pbhagavatula@caviumnetworks.com>
The current work cycles function exchanges source and destination mac
address and also pauses the core for the given cycles.
This patch splits the function into two parts i.e. exchange mac and
pause the cores. The pause cores function is invoked at every stage
where as exchange mac is invoked when packet is transmitted.
