help
Atheros' idea of regulatory handling is that the EEPROM of the card defines
the regulatory limits and the user is only allowed to restrict the settings
even further, even if the country allows frequencies or power levels that
are forbidden by the EEPROM settings.
Select this option if you want the driver to respect the user's decision about
regulatory settings.
