$ devlink resource show pci/0000:03:00.0
pci/0000:03:00.0:

 resources:
   name linear size 98304 occ 0
   name hash_double size 60416
   name hash_single size 87040

So this 2700 has 3 resources that can be managed -- some table or
resource or something named 'kvd' with linear, hash_double and
hash_single sub-resources. What are these names referring too? The above
output gives no description, and 'kvd' is not an industry term. Further,

This are internal resources specific to the ASIC. Would you like some
description to each or something like that?

The fact you have decided to expose them means you expect people to
change them. So yes, they need to be documented. Maybe add something
to Documentation/ABI/stable/

So the showed relation to dpipe table would be enougn or you would still
like to see some description? I don't like the description concept here
as the relations to dpipe table should tell user exactly what he needs
to know.

Documenting the ABI is good practice.

This is misunderstanding I believe. This is not about ABI. That is well
defined by the netlink attributes. This is about meaning of particular
ASIC-specific internal resources.
