+        These books attempt to give a description of the
+        various subsystems that play a role in 802.11 wireless
+        networking in Linux. Since these books are for kernel
+        developers they attempts to document the structures
+        and functions used in the kernel as well as giving a
+        higher-level overview.

+        The reader is expected to be familiar with the 802.11
+        standard as published by the IEEE in 802.11-2007 (or
+        possibly later versions). References to this standard
+        will be given as "802.11-2007 8.1.5".

-Generally, this document shall be ordered by increasing complexity.
-It is important to note that readers should be able to read only

-    <title>The basic mac80211 driver interface</title>
-    <partintro>
-      <para>
-        You should read and understand the information contained
-        within this part of the book while implementing a driver.
-        In some chapters, advanced usage is noted, that may be
-        skipped at first.
-      </para>
-      <para>
-        This part of the book only covers station and monitor mode
-        functionality, additional information required to implement
-        the other modes is covered in the second part of the book.

-      </para>
-      <para>
-        Since it is required to allocate rates/modes before registering
-        a hw struct, this chapter shall also contain information on setting
-        up the rate/mode structs.
-      </para>
-      <para>
-        Additionally, some discussion about the callbacks and
-        the general programming model should be in here, including
-        the definition of ieee80211_ops which will be referred to
-        a lot.
-      </para>
-      <para>
-        Finally, a discussion of hardware capabilities should be done
-        with references to other parts of the book.

 /**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ *       these registrations are ignored until the interface type is
+ *       changed again. This means that changing the interface type can
+ *       lead to a situation that couldn't otherwise be produced, but
+ *       any such registrations will be dormant in the sense that they
+ *       will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+ * 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.
