-config CFG80211

-
-config NL80211
-	bool "nl80211 new netlink interface support"
-	depends on CFG80211
-	default y
-	---help---
-	  This option turns on the new netlink interface
-	  (nl80211) support in cfg80211.
-
-	  If =n, drivers using mac80211 will be configured via
-	  wireless extension support provided by that subsystem.
-
-	  If unsure, say Y.
-
-config WIRELESS_EXT
-	bool "Wireless extensions"
-	default n
-	---help---
-	  This option enables the legacy wireless extensions
-	  (wireless network interface configuration via ioctls.)
-
-	  Wireless extensions will be replaced by cfg80211 and
-	  will be required only by legacy drivers that implement
-	  wireless extension handlers. This option does not
-	  affect the wireless-extension backward compatibility
-	  code in cfg80211.
-
-	  Say N (if you can) unless you know you need wireless
-	  extensions for external modules.

- * 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)
- *
- * 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.txt

- * History :
- * -------
- *
- * v1 - 5.12.01 - Jean II
- *	o Created this file.
- *
- * v2 - 13.12.01 - Jean II
- *	o Move /proc/net/wireless stuff from net/core/dev.c to here
- *	o Make Wireless Extension IOCTLs go through here
- *	o Added iw_handler handling ;-)
- *	o Added standard ioctl description
- *	o Initial dumb commit strategy based on orinoco.c
- *
- * v3 - 19.12.01 - Jean II
- *	o Make sure we don't go out of standard_ioctl[] in ioctl_standard_call
- *	o Add event dispatcher function
- *	o Add event description
- *	o Propagate events as rtnetlink IFLA_WIRELESS option
- *	o Generate event on selected SET requests
- *
- * v4 - 18.04.02 - Jean II
- *	o Fix stupid off by one in iw_ioctl_description : IW_ESSID_MAX_SIZE + 1
- *
- * v5 - 21.06.02 - Jean II
- *	o Add IW_PRIV_TYPE_ADDR in priv_type_size (+cleanup)
- *	o Reshuffle IW_HEADER_TYPE_XXX to map IW_PRIV_TYPE_XXX changes
- *	o Add IWEVCUSTOM for driver specific event/scanning token
- *	o Turn on WE_STRICT_WRITE by default + kernel warning
