  24 * This informs the wireless core that a beacon from an AP was found on
  25 * the channel provided. This allows the wireless core to make educated
  26 * guesses on regulatory to help with world roaming. This is only used for
  27 * world roaming -- when we do not know our current location. This is
  28 * only useful on channels 12, 13 and 14 on the 2 GHz band as channels
  29 * 1-11 are already enabled by the world regulatory domain; and on
  30 * non-radar 5 GHz channels.
  31 *
  32 * Drivers do not need to call this, cfg80211 will do it for after a scan
  33 * on a newly found BSS. If you cannot make use of this feature you can
  34 * set the wiphy->disable_beacon_hints to true.
