  23           cfg80211 is the Linux wireless LAN (802.11) configuration API.
  24           Enable this if you have a wireless device.

  36           The nl80211 testmode command helps implementing things like
  37           factory calibration or validation tools for wireless chips.
  38
  39           Select this option ONLY for kernels that are specifically
  40           built for such purposes.

  42           Debugging tools that are supposed to end up in the hands of

  52           This option enables some additional warnings that help
  53           cfg80211 developers and driver developers, but beware that
  54           they can also trigger due to races with userspace.
  55
  56           For example, when a driver reports that it was disconnected
  57           from the AP, but the user disconnects manually at the same
  58           time, the warning might trigger spuriously due to races.
  59
  60           Say Y only if you are developing cfg80211 or a driver based
  61           on it (or mac80211).

  68         ---help---
  69           You should disable this option unless you are both capable
  70           and willing to ensure your system will remain regulatory
  71           compliant with the features available under this option.
  72           Some options may still be under heavy development and
  73           for whatever reason regulatory compliance has not or
  74           cannot yet be verified. Regulatory verification may at
  75           times only be possible until you have the final system
  76           in place.
  77
  78           This option should only be enabled by system integrators
  79           or distributions that have done work necessary to ensure
  80           regulatory certification on the system with the enabled
  81           features. Alternatively you can enable this option if
  82           you are a wireless researcher and are working in a controlled
  83           and approved environment by your local regulatory agency.
  84
  85 config CFG80211_REG_CELLULAR_HINTS
  86         bool "cfg80211 regulatory support for cellular base station hints"
  87         depends on CFG80211_CERTIFICATION_ONUS
  88         ---help---
  89           This option enables support for parsing regulatory hints
  90           from cellular base stations. If enabled and at least one driver
  91           claims support for parsing cellular base station hints the
  92           regulatory core will allow and parse these regulatory hints.
  93           The regulatory core will only apply these regulatory hints on
  94           drivers that support this feature. You should only enable this
  95           feature if you have tested and validated this feature on your
  96           systems.
  97
  98 config CFG80211_REG_RELAX_NO_IR
  99         bool "cfg80211 support for NO_IR relaxation"
 100         depends on CFG80211_CERTIFICATION_ONUS
 101         ---help---
 102          This option enables support for relaxation of the NO_IR flag for
 103          situations that certain regulatory bodies have provided clarifications
 104          on how relaxation can occur. This feature has an inherent dependency on
 105          userspace features which must have been properly tested and as such is
 106          not enabled by default.
 107
 108          A relaxation feature example is allowing the operation of a P2P group
 109          owner (GO) on channels marked with NO_IR if there is an additional BSS
 110          interface which associated to an AP which userspace assumes or confirms
 111          to be an authorized master, i.e., with radar detection support and DFS
 112          capabilities. However, note that in order to not create daisy chain
 113          scenarios, this relaxation is not allowed in cases where the BSS client
 114          is associated to P2P GO and in addition the P2P GO instantiated on
 115          a channel due to this relaxation should not allow connection from
 116          non P2P clients.
 117
 118          The regulatory core will apply these relaxations only for drivers that
 119          support this feature by declaring the appropriate channel flags and
 120          capabilities in their registration flow.

 127           This option enables powersave mode by default.
 128
 129           If this causes your applications to misbehave you should fix your
 130           applications instead -- they need to register their network
 131           latency requirement, see Documentation/power/pm_qos_interface.txt.

 158           This option generates an internal data structure representing
 159           the wireless regulatory rules described in net/wireless/db.txt
 160           and includes code to query that database. This is an alternative
 161           to using CRDA for defining regulatory rules for the kernel.
 162
 163           Using this option requires some parsing of the db.txt at build time,
 164           the parser will be upkept with the latest wireless-regdb updates but
 165           older wireless-regdb formats will be ignored. The parser may later
 166           be replaced to avoid issues with conflicts on versions of
 167           wireless-regdb.
