/**
- * __regulatory_hint - hint to the wireless core a regulatory domain
- * @wiphy: if the hint comes from country information from an AP, this
- * is required to be set to the wiphy that received the information
- * @alpha2: the ISO/IEC 3166 alpha2 being claimed the regulatory domain
- * should be in.
- * @country_ie_checksum: checksum of processed country IE, set this to 0
- * if the hint did not come from a country IE
- * @country_ie_env: the environment the IE told us we are in, %ENVIRON_*
- *
- * The Wireless subsystem can use this function to hint to the wireless core
- * what it believes should be the current regulatory domain by giving it an
- * ISO/IEC 3166 alpha2 country code it knows its regulatory domain should be
- * in.
+ * regulatory_hint_found_beacon - hints a beacon was found on a channel
+ * @wiphy: the wireless device where the beacon was found on
+ * @beacon_chan: the channel on which the beacon was found on
+ * @gfp: context flags
*
- * Returns zero if all went fine, %-EALREADY if a regulatory domain had
- * already been set or other standard error codes.
+ * This informs the wireless core that a beacon from an AP was found on
+ * the channel provided. This allows the wireless core to make educated
+ * guesses on regulatory to help with world roaming. This is only used for
+ * world roaming -- when we do not know our current location. This is
+ * only useful on channels 12, 13 and 14 on the 2 GHz band as channels
+ * 1-11 are already enabled by the world regulatory domain; and on
+ * non-radar 5 GHz channels.
*
+ * Drivers do not need to call this, cfg80211 will do it for after a scan
+ * on a newly found BSS.
