Subject: [dpdk-dev] [PATCH v2 04/11] examples/l3fwd: add ethdev setup based on eventdev
Date: Wed, 4 Dec 2019 20:13:37 +0530
Message-ID: <20191204144345.5736-5-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20191204144345.5736-1-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.
