Subject: [PATCH v2 net-next 0/5] net: switchdev: Tracepoints

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.

Tobias Waldekranz (5):
  net: switchdev: Wrap enums in mapper macros
  net: switchdev: Add helpers to display switchdev objects as strings
  net: switchdev: Relay all replay messages through a central function
  net: switchdev: Prepare deferred notifications before enqueuing them
  net: switchdev: Add tracepoints
