Oh OK, thanks for clarifying that. > I know that at least Atheros, Broadcom and Ralink hw can set > this, so I think we should have an API for nl80211 with iw support.

I'm not familiar with coverage class stuff, but since the Country IE is built on hostapd I take it this would be hostapd doing the tweaking back through nl80211 to the driver. Sound right?
