While the hardware is capable of performing learning on the CPU port,
it requires alot of additions to the bridge's forwarding path in order
to handle multi-destination traffic correctly.

Until that is in place, opt for the next best thing and let DSA sync
the relevant addresses down to the hardware FDB.
