This patchset aims to expose couple of already defined serial numbers
for mlx5 driver.

On top of that, it introduces new field, "function.uid" and exposes
that for mlx5 driver.

Example:

$ devlink dev info
pci/0000:08:00.0:
  driver mlx5_core
  serial_number e4397f872caeed218000846daa7d2f49
  board.serial_number MT2314XZ00YA
  function.uid MT2314XZ00YAMLNXS0D0F0
  versions:
      fixed:
        fw.psid MT_0000000894
      running:
        fw.version 28.41.1000
        fw 28.41.1000
      stored:
        fw.version 28.41.1000
        fw 28.41.1000
auxiliary/mlx5_core.eth.0:
  driver mlx5_core.eth
pci/0000:08:00.1:
  driver mlx5_core
  serial_number e4397f872caeed218000846daa7d2f49
  board.serial_number MT2314XZ00YA
  function.uid MT2314XZ00YAMLNXS0D0F1
  versions:
      fixed:
        fw.psid MT_0000000894
      running:
        fw.version 28.41.1000
        fw 28.41.1000
      stored:
        fw.version 28.41.1000
        fw 28.41.1000
auxiliary/mlx5_core.eth.1:
  driver mlx5_core.eth

The first patch just adds a small missing bit in devlink ynl spec.

Jiri Pirko (4):
  ynl: devlink: add missing board-serial-number
  net/mlx5: Expose serial numbers in devlink info
  devlink: add function unique identifier to devlink dev info
  net/mlx5: Expose function UID in devlink info
