Merge branch 'devlink-add-per-port-resource-support'
Tariq Toukan says:
====================
devlink: add per-port resource support
This series by Or adds devlink per-port resource support:
Currently, devlink resources are only available at the device level.
However, some resources are inherently per-port, such as the maximum
number of subfunctions (SFs) that can be created on a specific PF port.
This limitation prevents user space from obtaining accurate per-port
capacity information.
This series adds infrastructure for per-port resources in devlink core
and implements it in the mlx5 driver to expose the max_SFs resource
on PF devlink ports.
Patch #1 refactors resource functions to be generic
Patch #2 adds port-level resource registration infrastructure
Patch #3 registers SF resource on PF port representor in mlx5
Patch #4 adds devlink port resource registration to netdevsim for testing
Patch #5 adds dump support for device-level resources
Patch #6 includes port resources in the resource dump dumpit path
Patch #7 adds port-specific option to resource dump doit path
Patch #8 adds selftest for devlink port resource doit
Patch #9 documents port-level resources and full dump
Patch #10 adds resource scope filtering to resource dump
Patch #11 adds selftest for resource dump and scope filter
Patch #12 documents resource scope filtering
