Subject: [dpdk-dev] [PATCH v3 4/5] net/mlx5: select Rx/Tx callbacks when starting device
Date: Wed, 5 Jul 2017 11:12:27 -0700 [thread overview]
Message-ID: <0a63bddc25e2446c0f07bbb10397fabce733ac54.1499278209.git.yskoh@mellanox.com> (raw)
In-Reply-To: <cover.1499278209.git.yskoh@mellanox.com>
The callbacks are global to a device but the seletion is made every queue
configuration, which is redundant.
