Yes, that sounds useful. Bringing an interface UP means "I want a physical layer connection" in the network layer. If a card is UP I can do the follwing: - Passively listening on the medium (scanning traffic) - Checking for physical layer problems (e.g. signal levels, bandwith, duplex) - Being detected by NICs on the same network segment By bringing an interface DOWN, I administrativly FORBID this all. By bringing it UP, I adminstrativly ALLOW this all. This is what the admin expect "ip set link up/down" to do, nothing more, nothing less. "ifconfig" can do more, but this is for historical reasons and no useful example for an interface. If you could map all this somehow to a WLAN, you are on the right way. Everything beyond this can be done later or before. Maybe that helps you for developing useful admin interface.
