[net-next,v4,0/4] nfp: series of minor driver improvements

Message

This short series bundles two unrelated but small updates to the nfp
driver.

Patch1: Add new define for devlink string "board.part_number"
Patch2: Make use of this field in the nfp driver
Patch3: Add new 'dim' profiles
Patch4: Make use of these new profiles in the nfp driver

Changes since V3:
- Fixed: Documentation/networking/devlink/devlink-info.rst:150:
    WARNING: Title underline too short.

Changes since V2:
- After some discussion on the previous series it was agreed that only
  the "board.part_number" field makes sense in the common code. The
  "board.model" field which was moved to devlink common code in V1 is
  now kept in the driver. The field is specific to the nfp driver,
  exposing the codename of the board.
- In summary, add "board.part_number" to devlink, and populate it
  in the the nfp driver.

Changes since V1:
- Move nfp local defines to devlink common code as it is quite generic.
- Add new 'dim' profile instead of using driver local overrides, as this
  allows use of the 'dim' helpers.
- This expanded 2 patches to 4, as the common code changes are split
  into seperate patches.

Fei Qin (4):
  devlink: add a new info version tag
  nfp: update devlink device info output
  dim: introduce a specific dim profile for better latency
  nfp: use new dim profiles for better latency
