Merge branch 'mlx5_active_speed' into rdma.git for-next 

Leon Romanovsky says:

====================
IBTA declares speed as 16 bits, but kernel stores it in u8. This series
fixes in-kernel declaration while keeping external interface intact.
====================

Based on the mlx5-next branch at
     git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
due to dependencies.

* branch 'mlx5_active_speed':
  RDMA: Fix link active_speed size
  RDMA/mlx5: Delete duplicated mlx5_ptys_width enum
  net/mlx5: Refactor query port speed functions
