It is a debatable whether this is correct behaviour.
My current opinion is that it needs to forward STP packets if
STP is off. This would allow for loop detection by other bridges
doing STP.

Longer term, RSTP needs to be fully integrated and default to on.
That way the average user will be safe from loops.
