+/**
+ * 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.
