With this series, users can query per-port resources:

$ devlink port resource show pci/0000:03:00.0/196608
pci/0000:03:00.0/196608:
  name max_SFs size 20 unit entry

$ devlink port resource show
pci/0000:03:00.0/196608:
  name max_SFs size 20 unit entry
pci/0000:03:00.1/262144:

Code LGTM, I have a question about having a new cmd, tho.

Does it matter to the user how the resource is scoped? 
Whether the resource is at the instance level or at the port level?

I worry we are mechanically following the design of other commands.
Since the dump handler is new we could just dump resources with port-id
there. No existing user space may be using it. Alternatively we could
add a new attribute to select a bitmask of which scope user wants to
dump.

I have a strong suspicion that the user will want to access all
resources of a device. `devlink resource show [$dev]` should dump 
all resources devlink knows about, including port ones.

What's the reason for the new command?
