Hi,

This series by Or adds devlink per-port resource support.
See detailed description by Or below [1].

Regards,
Tariq

[1]
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

V4:
- Link to V3:
  https://lore.kernel.org/all/20260226221916.1800227-1-tariqt@nvidia.com/
- Remove new devlink port resource command
- Add devlink resource show for all resources (devices + ports) via
  dumpit
- Add scope parameter to dump (scope dev / scope port)
- Extend the doit command with port handle option while preserving the
  legacy dev doit path
