Using GeoClue to send a Linux wireless regulatory hint

[Hin-Tak Leung]

I thought the reason for using GeoClue is to cater for frequent
travellers who can cross timezone (and not neccesarily reset their
laptop's computer/clock for it)? So it is orthogonal to one-off static
setup where the computer mostly stay in the same country/location. Is
there an iw/cfg80211 interface/field for regulatory info? AFAIK there
isn't in wext, but that's on its way out and probably not important...
