devlink: avoid param type value translations

2025-05-07T01:21:11Z

Assign DEVLINK_PARAM_TYPE_* enum values to DEVLINK_VAR_ATTR_TYPE_* to ensure the same values are used internally and in UAPI. Benefit from that by removing the value translations.

devlink: define enum for attr types of dynamic attributes

2025-05-07T01:21:11Z

Devlink param and health reporter fmsg use attributes with dynamic type which is determined according to a different type. Currently used values are NLA_*. The problem is, they are not part of UAPI. They may change which would cause a break. To make this future safe, introduce a enum that shadows NLA_* values in it and is part of UAPI. Also, this allows to possibly carry types that are unrelated to NLA_* values.

devlink: extend devlink_param *set pointer

2024-04-22T20:05:19Z

Extend devlink_param *set function pointer to take extack as a param. Sometimes it is needed to pass information to the end user from set function. It is more proper to use for that netlink instead of passing message to dmesg. Reviewed-by: Jiri Pirko Reviewed-by: Przemek Kitszel Signed-off-by: Mateusz Polchlopek Signed-off-by: Tony Nguyen
