Re: rfkill vs. interface up

That proposal sounds fine to me from a userspace perspective.  Sane
implementations don't assume the interface is IFF_UP when they configure
the device anyway (since it's not necessarily up at boot time or after
hibernate for example), and since you need a reconfigure after rfkill,
this seems reasonable.

You wouldn't have to give up on txpower either, you could simply map
'txpower off' to SW-rfkill, and 'txpower on' to un-SW-rfkill, where of
course the interface would be !IFF_UP after 'txpower on' just like
flipping the killswitch would.

Yeah, good point, that sounds better than having to give up on it -- the
key though is that we can't recover IFF_UP state when that happens; if
that's ok this should be fairly simple.
