[PATCH net-next 0/5] Fast ageing support for SJA1105 DSA driver

While adding support for flushing dynamically learned FDB entries in the
sja1105 driver, I noticed a few things that could be improved in DSA.
Most notably, drivers could omit a fast age when address learning is
turned off, which might mean that ports leaving a bridge and becoming
standalone could still have FDB entries pointing towards them. Secondly,
when DSA fast ages a port after the 'learning' flag has been turned off,
the software bridge still has the dynamically learned 'master' FDB
entries installed, and those should be deleted too.
