Subject: [PATCH net-next 1/4] mlx4/mlx5: {mlx4,mlx5e}_en_get_module_info
cleanup
Use SFF8024 constants defined in linux/sfp.h instead of private ones.
Make mlx4_en_get_module_info() and mlx5e_get_module_info() to look
as close as possible to each other.
Simplify the logic for selecting SFF_8436 vs SFF_8636.
