- * 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.
+ * 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.
  *
- * Returns zero if all went fine, %-EALREADY if a regulatory domain had
- * already been set or other standard error codes.
- *
+ * Drivers do not need to call this, cfg80211 will do it for after a scan
+ * on a newly found BSS.
