We do not want to keep static regulatory domains in the kernel due to the the dynamic nature of regulatory law and localization. We kept around the old static definitions for the regulatory domains of: + * US * JP * EU + and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was - set. We also kept around the ieee80211_regdom module parameter in case - some applications were relying on it.
