Hi Linu,
This looks like a good approach to me.
However I think you also also need to add documentation for npc_def_rule_cntr
to Documentation/networking/devlink/octeontx2.rst
Likewise, octeontx2.rst seems to be missing documentation for the existing
AF parameters npc_mcam_high_zone_percent and nix_maxlf. I did not see
if there are any more undocumented parameters for octeontx2 but I'd
appreciate if you could do so.
