Subject: [PATCH 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.

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
