+	  cfg80211 is the Linux wireless LAN (802.11) configuration API.
+	  Enable this if you have a wireless device.
+
+	  For more information refer to documentation on the wireless wiki:
+
+	  https://wireless.wiki.kernel.org/en/developers/Documentation/cfg80211
+
+	  When built as a module it will be called cfg80211.
+

+
+config NL80211_TESTMODE
+	bool "nl80211 testmode command"
+	help
+	  The nl80211 testmode command helps implementing things like
+	  factory calibration or validation tools for wireless chips.
+
+	  Select this option ONLY for kernels that are specifically
+	  built for such purposes.
+
+	  Debugging tools that are supposed to end up in the hands of
+	  users should better be implemented with debugfs.
+
+	  Say N.
+
+config CFG80211_DEVELOPER_WARNINGS
+	bool "enable developer warnings"
+	default n
+	help
+	  This option enables some additional warnings that help
+	  cfg80211 developers and driver developers, but beware that
+	  they can also trigger due to races with userspace.
+
+	  For example, when a driver reports that it was disconnected
+	  from the AP, but the user disconnects manually at the same
+	  time, the warning might trigger spuriously due to races.
+
+	  Say Y only if you are developing cfg80211 or a driver based
+	  on it (or mac80211).
+
+
+config CFG80211_CERTIFICATION_ONUS
+	bool "cfg80211 certification onus"
+	depends on EXPERT
+	default n
+	help
+	  You should disable this option unless you are both capable
+	  and willing to ensure your system will remain regulatory
+	  compliant with the features available under this option.
+	  Some options may still be under heavy development and
+	  for whatever reason regulatory compliance has not or
+	  cannot yet be verified. Regulatory verification may at
+	  times only be possible until you have the final system
+	  in place.
+
+	  This option should only be enabled by system integrators
+	  or distributions that have done work necessary to ensure
+	  regulatory certification on the system with the enabled
+	  features. Alternatively you can enable this option if
+	  you are a wireless researcher and are working in a controlled
+	  and approved environment by your local regulatory agency.
+
+config CFG80211_REQUIRE_SIGNED_REGDB
+	bool "require regdb signature" if CFG80211_CERTIFICATION_ONUS
+	default y
+	select SYSTEM_DATA_VERIFICATION
+	help
+	  Require that in addition to the "regulatory.db" file a
+	  "regulatory.db.p7s" can be loaded with a valid PKCS#7
+	  signature for the regulatory.db file made by one of the
+	  keys in the certs/ directory.
+
+config CFG80211_USE_KERNEL_REGDB_KEYS
+	bool "allow regdb keys shipped with the kernel" if CFG80211_CERTIFICATION_ONUS
+	default y
+	depends on CFG80211_REQUIRE_SIGNED_REGDB
+	help
+	  Allow the regulatory database to be signed by one of the keys for
+	  which certificates are part of the kernel sources
+	  (in net/wireless/certs/).
+
+	  This is currently only Seth Forshee's key, who is the regulatory
+	  database maintainer.
+
+config CFG80211_EXTRA_REGDB_KEYDIR
+	string "additional regdb key directory" if CFG80211_CERTIFICATION_ONUS
+	depends on CFG80211_REQUIRE_SIGNED_REGDB
+	help
+	  If selected, point to a directory with DER-encoded X.509
+	  certificates like in the kernel sources (net/wireless/certs/)
+	  that shall be accepted for a signed regulatory database.
+
+	  Note that you need to also select the correct CRYPTO_<hash> modules
+	  for your certificates, and if cfg80211 is built-in they also must be.
+
+config CFG80211_REG_CELLULAR_HINTS
+	bool "cfg80211 regulatory support for cellular base station hints"
+	depends on CFG80211_CERTIFICATION_ONUS
+	help
+	  This option enables support for parsing regulatory hints
+	  from cellular base stations. If enabled and at least one driver
+	  claims support for parsing cellular base station hints the
+	  regulatory core will allow and parse these regulatory hints.
+	  The regulatory core will only apply these regulatory hints on
+	  drivers that support this feature. You should only enable this
+	  feature if you have tested and validated this feature on your
+	  systems.
+
+config CFG80211_REG_RELAX_NO_IR
+	bool "cfg80211 support for NO_IR relaxation"
+	depends on CFG80211_CERTIFICATION_ONUS
+	help
+	 This option enables support for relaxation of the NO_IR flag for
+	 situations that certain regulatory bodies have provided clarifications
+	 on how relaxation can occur. This feature has an inherent dependency on
+	 userspace features which must have been properly tested and as such is
+	 not enabled by default.
+
+	 A relaxation feature example is allowing the operation of a P2P group
+	 owner (GO) on channels marked with NO_IR if there is an additional BSS
+	 interface which associated to an AP which userspace assumes or confirms
+	 to be an authorized master, i.e., with radar detection support and DFS
+	 capabilities. However, note that in order to not create daisy chain
+	 scenarios, this relaxation is not allowed in cases where the BSS client
+	 is associated to P2P GO and in addition the P2P GO instantiated on
+	 a channel due to this relaxation should not allow connection from
+	 non P2P clients.
+
+	 The regulatory core will apply these relaxations only for drivers that
+	 support this feature by declaring the appropriate channel flags and
+	 capabilities in their registration flow.
+
+config CFG80211_DEFAULT_PS
+	bool "enable powersave by default"
+	default y
+	help
+	  This option enables powersave mode by default.
+
+	  If this causes your applications to misbehave you should fix your
+	  applications instead -- they need to register their network
+	  latency requirement, see Documentation/power/pm_qos_interface.rst.
+
+config CFG80211_DEBUGFS
+	bool "cfg80211 DebugFS entries"
+	depends on DEBUG_FS
+	help
+	  You can enable this if you want debugfs entries for cfg80211.
+
+	  If unsure, say N.
+
+config CFG80211_CRDA_SUPPORT
+	bool "support CRDA" if EXPERT
+	default y
+	help
+	  You should enable this option unless you know for sure you have no
+	  need for it, for example when using the regulatory database loaded as
+	  a firmware file.
+
+	  If unsure, say Y.
+
+config CFG80211_WEXT
+	bool "cfg80211 wireless extensions compatibility" if !CFG80211_WEXT_EXPORT
+	select WEXT_CORE
+	default y if CFG80211_WEXT_EXPORT
+	help
+	  Enable this option if you need old userspace for wireless
+	  extensions with cfg80211-based drivers.
+
+config CFG80211_WEXT_EXPORT
+	bool
+	help
+	  Drivers should select this option if they require cfg80211's
+	  wext compatibility symbols to be exported.
+
+endif # CFG80211
+
+config LIB80211
+	tristate
+	default n
+	help
+	  This options enables a library of common routines used
+	  by IEEE802.11 wireless LAN drivers.
+
+	  Drivers should select this themselves if needed.
+
+config LIB80211_CRYPT_WEP
+	tristate

+	help
+	  You can enable this if you want verbose debugging messages
+	  from lib80211.
+

+ * ieee80211_radiotap_iterator_init - radiotap parser iterator initialization
+ * @iterator: radiotap_iterator to initialize
+ * @radiotap_header: radiotap header to parse
+ * @max_length: total length we can parse into (eg, whole packet length)
+ * @vns: vendor namespaces to parse
+ *
+ * Returns: 0 or a negative error code if there is a problem.
+ *
+ * This function initializes an opaque iterator struct which can then
+ * be passed to ieee80211_radiotap_iterator_next() to visit every radiotap
+ * argument which is present in the header.  It knows about extended
+ * present headers and handles them.
+ *
+ * How to use:
+ * call __ieee80211_radiotap_iterator_init() to init a semi-opaque iterator
+ * struct ieee80211_radiotap_iterator (no need to init the struct beforehand)
+ * checking for a good 0 return code.  Then loop calling
+ * __ieee80211_radiotap_iterator_next()... it returns either 0,
+ * -ENOENT if there are no more args to parse, or -EINVAL if there is a problem.
+ * The iterator's @this_arg member points to the start of the argument
+ * associated with the current argument index that is present, which can be
+ * found in the iterator's @this_arg_index member.  This arg index corresponds
+ * to the IEEE80211_RADIOTAP_... defines.
+ *
+ * Radiotap header length:
+ * You can find the CPU-endian total radiotap header length in
+ * iterator->max_length after executing ieee80211_radiotap_iterator_init()
+ * successfully.
+ *
+ * Alignment Gotcha:
+ * You must take care when dereferencing iterator.this_arg
+ * for multibyte types... the pointer is not aligned.  Use
+ * get_unaligned((type *)iterator.this_arg) to dereference
+ * iterator.this_arg for type "type" safely on all arches.
+ *
+ * Example code:
+ * See Documentation/networking/radiotap-headers.rst

+/**
+ * DOC: Wireless regulatory infrastructure
+ *
+ * The usual implementation is for a driver to read a device EEPROM to
+ * determine which regulatory domain it should be operating under, then
+ * looking up the allowable channels in a driver-local table and finally
+ * registering those channels in the wiphy structure.
+ *
+ * Another set of compliance enforcement is for drivers to use their
+ * own compliance limits which can be stored on the EEPROM. The host
+ * driver or firmware may ensure these are used.
+ *
+ * In addition to all this we provide an extra layer of regulatory
+ * conformance. For drivers which do not have any regulatory
+ * information CRDA provides the complete regulatory solution.
+ * For others it provides a community effort on further restrictions
+ * to enhance compliance.
+ *
+ * Note: When number of rules --> infinity we will not be able to
+ * index on alpha2 any more, instead we'll probably have to
+ * rely on some SHA1 checksum of the regdomain for example.

+ * DOC: BSS tree/list structure
+ *
+ * At the top level, the BSS list is kept in both a list in each
+ * registered device (@bss_list) as well as an RB-tree for faster
+ * lookup. In the RB-tree, entries can be looked up using their
+ * channel, MESHID, MESHCONF (for MBSSes) or channel, BSSID, SSID
+ * for other BSSes.
+ *
+ * Due to the possibility of hidden SSIDs, there's a second level
+ * structure, the "hidden_list" and "hidden_beacon_bss" pointer.
+ * The hidden_list connects all BSSes belonging to a single AP
+ * that has a hidden SSID, and connects beacon and probe response
+ * entries. For a probe response entry for a hidden SSID, the
+ * hidden_beacon_bss pointer points to the BSS struct holding the
+ * beacon's information.
+ *
+ * Reference counting is done for all these references except for
+ * the hidden_list, so that a beacon BSS struct that is otherwise
+ * not referenced has one reference for being on the bss_list and
+ * one for each probe response entry that points to it using the
+ * hidden_beacon_bss pointer. When a BSS struct that has such a
+ * pointer is get/put, the refcount update is also propagated to
+ * the referenced struct, this ensure that it cannot get removed
+ * while somebody is using the probe response version.
+ *
+ * Note that the hidden_beacon_bss pointer never changes, due to
+ * the reference counting. Therefore, no locking is needed for
+ * it.
+ *
+ * Also note that the hidden_beacon_bss pointer is only relevant
+ * if the driver uses something other than the IEs, e.g. private
+ * data stored in the BSS struct, since the beacon IEs are
+ * also linked into the probe response struct.
+ */
+
+/*
+ * Limit the number of BSS entries stored in mac80211. Each one is
+ * a bit over 4k at most, so this limits to roughly 4-5M of memory.
+ * If somebody wants to really attack this though, they'd likely
+ * use small beacons, and only one type of frame, limiting each of
+ * the entries to a much smaller size (in order to generate more
+ * entries in total, so overhead is bigger.)
