26 * DOC: Introduction
27 *
28 * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
29 * userspace and drivers, and offers some utility functionality associated
30 * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
31 * by all modern wireless drivers in Linux, so that they offer a consistent
32 * API through nl80211. For backward compatibility, cfg80211 also offers
33 * wireless extensions to userspace, but hides them from drivers completely.
34 *
35 * Additionally, cfg80211 contains code to help enforce regulatory spectrum
36 * use restrictions.

41 * DOC: Device registration
42 *
43 * In order for a driver to use cfg80211, it must register the hardware device
44 * with cfg80211. This happens through a number of hardware capability structs
45 * described below.
46 *
47 * The fundamental structure for each device is the 'wiphy', of which each
48 * instance describes a physical wireless device connected to the system. Each
49 * such wiphy can have zero, one, or many virtual interfaces associated with
50 * it, which need to be identified as such by pointing the network interface's
51 * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
52 * the wireless part of the interface, normally this struct is embedded in the
53 * network interface's private data area. Drivers can optionally allow creating
54 * or destroying virtual interfaces on the fly, but without at least one or the
55 * ability to create some the wireless device isn't useful.
56 *
57 * Each wiphy structure contains device capability information, and also has
58 * a pointer to the various operations the driver offers. The definitions and
59 * structures here describe these capabilities in detail.

1358 * DOC: Scanning and BSS list handling
1359 *
1360 * The scanning process itself is fairly simple, but cfg80211 offers quite
1361 * a bit of helper functionality. To start a scan, the scan operation will
1362 * be invoked with a scan definition. This scan definition contains the
1363 * channels to scan, and the SSIDs to send probe requests for (including the
1364 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1365 * probe. Additionally, a scan request may contain extra information elements
1366 * that should be added to the probe request. The IEs are guaranteed to be
1367 * well-formed, and will not exceed the maximum length the driver advertised
1368 * in the wiphy structure.
1369 *
1370 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1371 * it is responsible for maintaining the BSS list; the driver should not
1372 * maintain a list itself. For this notification, various functions exist.
1373 *
1374 * Since drivers do not maintain a BSS list, there are also a number of
1375 * functions to search for a BSS and obtain information about it from the
1376 * BSS structure cfg80211 maintains. The BSS list is also made available
1377 * to userspace.
