-This generation of chips contain additional ​ regulatory support independent of the driver. The devices use a single ​ worldwide regulatory domain, with channels ​12-14 (2.4 GHz band) and  channels 52-64 and 100-140 (5 GHz band) restricted to passive operation. ​ Transmission on those channels is suppressed until appropriate other  traffic is observed on those channels. Within the driver, we use the  ficticious country code "​X2"​ to represent this worldwide regulatory ​ domain. There is currently no interface to configure a different domain. ​ The driver reads the SROM country code from the chip and hands it up to  mac80211 as the regulatory hint, however this information is otherwise ​ unused with the driver. ​+This generation of chips contain additional ​ regulatory support independent of the driver.
