From 321f7ab0d45899fe0313139822d69c2d5adbb760 Mon Sep 17 00:00:00 2001 From: Danielle Ratson Date: Thu, 21 Jan 2021 15:10:23 +0200 Subject: mlxsw: Register physical ports as a devlink resource The switch ASIC has a limited capacity of physical ('flavour physical' in devlink terminology) ports that it can support. While each system is brought up with a different number of ports, this number can be increased via splitting up to the ASIC's limit. Expose physical ports as a devlink resource so that user space will have visibility to the maximum number of ports that can be supported and the current occupancy. In addition, add a "Generic Resources" section in devlink-resource documentation so the different drivers will be aligned by the same resource name when exposing to user space.
