====================
mlxsw: Various trap changes - part 1

This patch set contains various changes in mlxsw trap configuration.
Another set will perform similar changes before exposing control traps
(e.g., IGMP query, ARP request) via devlink-trap.

Tested with existing devlink-trap selftests. Please see individual
patches for a detailed changelog.
====================
