Again, dsa_port_fast_age() is also called when dp->learning is turned off in dsa_port_bridge_flags(). I don't want to see the mv88e6xxx driver doing this manually.

But I think it should be so that turning MAB off will clear the ALE entries regardless, as the port can continue to be locked and needing port association, or you want them to just age out normally in that case, thus lingering for up to bridge ageing time?
