You told me to split few patches from first patchset [1]. We agree that
there will be too many patches for one submission, so I split it into
3:
- 1/3 devlink prework (already accepted)
- 2/3 base subfunction (this patchset)
- 3/3 port representor refactor to support subfunction (I am going to
  include it there)
