Subject: [net-next v2 03/15] net/mlx5: Move all devlink related functions calls to devlink.c
Date: Thu, 13 Jun 2019 20:39:19 +0000	[thread overview]
Message-ID: <20190613203825.31049-4-saeedm@mellanox.com> (raw)
In-Reply-To: <20190613203825.31049-1-saeedm@mellanox.com>

From: Eran Ben Elisha <eranbe@mellanox.com>

Centralize all devlink related callbacks in one file.
In the downstream patch, some more functionality will be added, this
patch is preparing the driver infrastructure for it.

Currently, move devlink un/register functions calls into this file.
