Subject: [PATCH net-next v2 0/4] net: pse-pd: pd692x0: Add permanent
 configuration management support

From: Kory Maincent (Dent Project) <kory.maincent@...tlin.com>

This patch series adds support for saving and resetting the PD692x0
device's permanent configuration through driver devlink param attributes:
PD692X0_DEVLINK_PARAM_ID_SAVE_CONF and PD692X0_DEVLINK_PARAM_ID_RESET_CONF.

The permanent configuration allows settings to persist across device
resets and power cycles, providing better control over PSE behavior
in production environments.

Changes in v2:
- Move from sysfs interface to devlink interface for the permanent
  configuration support
- Remove the __free macro from pd692x0 driver following net policy.
- Link to v1: https://lore.kernel.org/r/20250822-feature_poe_permanent_conf-v1-0-dcd41290254d@bootlin.com
