In this example, would a wireless wifi-iface have
	option network 'lan' # bridge device name?
	option network 'home' # logical name?

Since the wifi-iface is added as another port on a bride, then I would
say 'lan'.  But on the other hand, a wifi-iface does not have to be
bridged to any physical ports.  In this case, I would say 'home' is correct.
