They don't, and the code therein is quite clear about that. Btw., I've seen
some other drivers around that didn't allow this (although those were some
probably-unreleased pieces of code).

Is there a clear definition in wext of how device drivers implementing it
should behave in this respect?
(I'm going to try just bringing the interface down&up in driver_wext_associate,
just to see if it breaks anything else..)
