1074 * struct wiphy - wireless hardware description
1075 * @idx: the wiphy index assigned to this item
1076 * @class_dev: the class device representing /sys/class/ieee80211/<wiphy-name>
1077 * @custom_regulatory: tells us the driver for this device
1078 * has its own custom regulatory domain and cannot identify the
1079 * ISO / IEC 3166 alpha2 it belongs to. When this is enabled
1080 * we will disregard the first regulatory hint (when the
1081 * initiator is %REGDOM_SET_BY_CORE).
1082 * @strict_regulatory: tells us the driver for this device will ignore
1083 * regulatory domain settings until it gets its own regulatory domain
1084 * via its regulatory_hint(). After its gets its own regulatory domain
1085 * it will only allow further regulatory domain settings to further
1086 * enhance compliance. For example if channel 13 and 14 are disabled
1087 * by this regulatory domain no user regulatory domain can enable these
1088 * channels at a later time. This can be used for devices which do not
1089 * have calibration information gauranteed for frequencies or settings
1090 * outside of its regulatory domain.
Luis R. Rodriguez37184242009-07-30 17:43:48 -07001091 * @disable_beacon_hints: enable this if your driver needs to ensure that
1092 * passive scan flags and beaconing flags may not be lifted by cfg80211
1093 * due to regulatory beacon hints. For more information on beacon
1094 * hints read the documenation for regulatory_hint_found_beacon()
Johannes Bergd3236552009-04-20 14:31:42 +02001095 * @reg_notifier: the driver's regulatory notification callback
1096 * @regd: the driver's regulatory domain, if one was requested via
1097 * the regulatory_hint() API. This can be used by the driver
1098 * on the reg_notifier() if it chooses to ignore future
1099 * regulatory domain changes caused by other drivers.
1100 * @signal_type: signal type reported in &struct cfg80211_bss.
1101 * @cipher_suites: supported cipher suites
1102 * @n_cipher_suites: number of supported cipher suites
Jouni Malinenb9a5f8ca2009-04-20 18:39:05 +02001103 * @retry_short: Retry limit for short frames (dot11ShortRetryLimit)
1104 * @retry_long: Retry limit for long frames (dot11LongRetryLimit)
1105 * @frag_threshold: Fragmentation threshold (dot11FragmentationThreshold);
1106 * -1 = fragmentation disabled, only odd values >= 256 used
1107 * @rts_threshold: RTS threshold (dot11RTSThreshold); -1 = RTS/CTS disabled
Johannes Berg463d0182009-07-14 00:33:35 +02001108 * @net: the network namespace this wiphy currently lives in

1113 * driver if it has a good reason to override the default
