Subject[PATCH 5.4 156/165] net/mlx5: Move devlink registration before interfaces load
Date
From: Michael Guralnik <michaelgur@mellanox.com>

[ 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")
