net: dsa: sja1105: Add P/Q/R/S management route support via dynamic interface
Management routes are one-shot FDB rules installed on the CPU port for
sending link-local traffic. They are a prerequisite for STP, PTP etc to
work.
Also make a note that removing a management route was not supported on
the previous generation of switches.
