Subject: [dpdk-dev] [PATCH v2] app/eventdev: add option to enable per port pool
Date: Thu, 1 Jul 2021 11:37:59 +0530	[thread overview]
Message-ID: <20210701060800.1096-1-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20210615103149.4194-1-pbhagavatula@marvell.com>

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Add option to configure unique mempool for each ethernet device
port. Can be used with `pipeline_atq` and `pipeline_queue` tests.

Signed-off-by: Pavan Nikhilesh <pbhagavatula@marvell.com>
