Entering the addresses in the uc list on other bridgeports seems
reasonable for the scenario described.
But would it _also_ need to be added to the fdb of the bridge?
i.e how does the bridge (if the packet was to be handed to it)
know where to forward?
BTW: on the comment that flooding off implies learning off: I would like
to be able to turn off flooding on a specific bridge port but
still want to learn from it. I dont think those two are mutually
exclusive.
