devlink: introduce a helper for netlink multicast send

2023-12-19T14:31:40+00:00

arguments.

devlink: send notifications only if there are listeners

2023-12-19T14:31:40+00:00

devlink: introduce __devl_is_registered() helper and use it instead of xa_get_mark()

2023-12-19T14:31:40+00:00

Introduce __devl_is_registered() which does not assert on devlink
instance lock and use it in notifications which may be called
without devlink instance lock held.

devlink: rename netlink callback to be aligned with the generated ones

2023-10-23T23:12:47+00:00

All remaining doit and dumpit netlink callback functions are going to be
used by generated split ops. They expect certain name format. Rename the
callback to be aligned with generated names.

devlink: expose peer SF devlink instance

2023-09-17T13:01:47+00:00

Introduce a new helper devl_port_fn_devlink_set() to be used by driver
assigning a devlink instance to the peer devlink port function.

Expose this to user over new netlink attribute nested under port
function nest to expose devlink handle related to the port function.

This is particularly helpful for user to understand the relationship
between devlink instances created for SFs and the port functions
they belong to.

Note that caller of devlink_port_notify() needs to hold devlink
instance lock, put the assertion to devl_port_fn_devlink_set() to make
this requirement explicit. Also note the limitations that only allow to
make this assignment for registered objects.

devlink: move linecard struct into linecard.c

2023-09-17T13:01:46+00:00

Instead of exposing linecard struct, expose a simple helper to get the
linecard index, which is all is needed outside linecard.c. Move the
linecard struct to linecard.c and keep it private similar to the rest of
the devlink objects.
