net/mlx5: Avoid deriving mlx5_core_dev second time
|
|
|
d8f823 |
|
|
|
d8f823 |
All callers needs to work on mlx5_core_dev and it is already derived
|
|
|
d8f823 |
before calling mlx5_devlink_eswitch_check().
|
|
|
d8f823 |
Hence, accept mlx5_core_dev in mlx5_devlink_eswitch_check().
|
|
|
d8f823 |
|
|
|
d8f823 |
Given that it works on mlx5_core_dev change helper function name to
|
|
|
d8f823 |
drop devlink prefix.
