Commit Message

Tobias Waldekranz Jan. 23, 2024, 3:37 p.m. UTC 
In order to avoid having to maintain separate mappings from enum
values to strings, wrap enumerators in mapper macros, so that
enum-to-string tables can be generated.

This will make it easier to create helpers that convert switchdev
objects to strings.
