Luis R. Rodrigueze38f8a72009-02-21 00:20:39 -050019 * regulatory_hint_found_beacon - hints a beacon was found on a channel
20 * @wiphy: the wireless device where the beacon was found on
21 * @beacon_chan: the channel on which the beacon was found on
22 * @gfp: context flags
23 *
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
Luis R. Rodriguez37184242009-07-30 17:43:48 -070033 * on a newly found BSS. If you cannot make use of this feature you can
34 * set the wiphy->disable_beacon_hints to true.
