Hi Jakub,

You are right, this info is never used/reported.

Alexander is extending already existing non used field with new values from
our latest hardware revisions.

I thought devlink info could be a good place to output such kind of information.

Thats basically a layout of *Physical* ports on device - quite useful info I
think.

Important thing is these ports may not be directly mapped to PCI PFs. So
reading `ethtool eth*` may not explain you the real device capabilities.

Do you think it makes sense adding such info to `devlink info` then?

Thanks
  Igor
