Subject: [dpdk-dev] [PATCH v5 04/11] examples/l3fwd: add ethdev setup based on eventdev
Date: Fri, 24 Jan 2020 09:35:35 +0530	[thread overview]
Message-ID: <20200124040542.2360-5-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20200124040542.2360-1-pbhagavatula@marvell.com>

From: Sunil Kumar Kori <skori@marvell.com>

Add ethernet port Rx/Tx queue setup for event device which are later
used for setting up event eth Rx/Tx adapters.
