mac80211: introduce hw config change flags
This makes mac80211 notify the driver which configuration actually changed, e.g. channel etc. No driver changes, this is just plumbing, driver authors are expected to act on this if they want to. Also remove the HW CONFIG debug printk, it's incorrect, often we configure something else. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
