Subject: [PATCH 19/24] net/mlx5: Move devlink registration before interfaces load

From: Michael Guralnik <[email-masked]>
Date: Wed, 20 Nov 2019 11:43:49 +0200

[ Upstream commit a6f3b62386a02c1e94bfa22c543f82d63f5e631b ]

Register devlink before interfaces are added.
This will allow interfaces to use devlink while initalizing. For example,
call mlx5_is_roce_enabled.

Fixes: aba25279c100 ("net/mlx5e: Add TX reporter support")
