This series starts off (1-2/5) by creating stringifiers for common
switchdev objects. This will primarily be used by the tracepoints for
decoding switchdev notifications, but drivers could also make use of
them to provide richer debug/error messages.
Then follows two refactoring commits (3-4/5), with no (intended)
functional changes:
- 3/5: Wrap all replay callbacks in br_switchdev.c in a switchdev
function to make it easy to trace all of these.
- 4/5: Instead of using a different format for deferred items, reuse
the existing notification structures when enqueuing. This lets
us share a bit more code, and it unifies the data presented by
the tracepoints.
Finally, add the tracepoints.
v1 -> v2:
- Fixup kernel-doc comment for switchdev_call_replay
I know that there are still some warnings issued by checkpatch, but
I'm not sure how to work around them, given the nature of the mapper
macros. Please advise.
