I need to iterate through all local->interfaces and
if they are stations, figure out if they are associated
or not.
I tried checking for existence of sdata->u.mgd.associated,
but it is always null (I'm using non-encrypted links
currently, in case that matters.)
I'd also like to know if any are authenticated.
I cannot figure out a clean way to do this..any suggestions?
Thanks,
Ben

That's correct, if it's always NULL then you're not associated properly
I guess?

Well, it seemed to work and passed traffic fine, so I'm at a loss. Perhaps
it just wasn't associated while one of the stations was scanning.
Either way, I added logic to iterate through all stas and check it's
flags, and that seems to work (see the can_scan_one patch logic I posted).
Thanks,
Ben
