I wasn't thinking of that, but instead, of the 'loop' cfg80211 would do upon regulatory change, on all wiphys. > Also, just providing the hook is much simpler and we can leave it up to > drivers to implement this logic. Hm, the drivers will still call a cfg80211 helper anyway to update its channel flags/power limits, why not let cfg80211 just do it then in a loop for all wiphys upon reg change? At the end of the loop for each wiphy we can call a driver-specific ops->verify_reg().
