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


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

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