Then your network breaks anyway? And you see messages in the log that it
failed to switch channel? We're talking about mac80211 devices :)

It's not just Intel... All fullmac devices, ie. everything not using
mac80211, shows the same behaviour.

And trying to say "current channel" is "hardware channel" runs into the
nice pitfall that, unfortunately, wext is so undefined that you can't
really say either. I think the channel it's trying to use makes a whole
lot more sense because otherwise a user who just randomly does
"iwconfig" will be mightily confused if for example wpa_supplicant had
just requested a scan.
