BCM5325 doesn't implement FAST_AGE registers so we should avoid reading or
writing them.

How about implementing a "slow age" procedure instead? Walk through the
FDB, and delete the dynamically learned entries for the port?

Address aging is important for STP state transitions.
That's a good suggestion, I suppose for now this can be b53 specific 
until we encounter another 20 year old switch and then we move that 
logic within the DSA framework?
