Can we make this a one step process and less visible to the user.
If user defines an uplink device, and the uplink device is capable of filtering
(and what ever other pre-conditions people can think of), then the bridge will
transparently switch to uplink/non-promisc mode.  This can also be used to trigger
edge only mode in RSTP in the future.

Less knobs.
