+Introduction
+============
+
+Explaining wireless 802.11 networking in the Linux kernel
+
+Copyright 2007-2009 Johannes Berg
+
+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".

+mac80211 subsystem (advanced)
+=============================
+
+Information contained within this part of the book is of interest only
+for advanced interaction of mac80211 with drivers to exploit more
+hardware capabilities and improve performance.
+
+LED support
+===========
+
+Mac80211 supports various ways of blinking LEDs. Wherever possible,
+device LEDs should be exposed as LED class devices and hooked up to the
+appropriate trigger, which will then be triggered appropriately by
+mac80211.

+===========================
+mac80211 subsystem (basics)
+===========================
+
+You should read and understand the information contained within this
+part of the book while implementing a mac80211 driver. In some chapters,
+advanced usage is noted, those may be skipped if this isn't needed.
+
+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.
+
+Basic hardware handling
+=======================
+
+TBD
+
+This chapter shall contain information on getting a hw struct allocated
+and registered with mac80211.
+
+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.
+
+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.
+
+Finally, a discussion of hardware capabilities should be done with
+references to other parts of the book.

+Virtual interfaces
+==================
+
+TBD
+
+This chapter should describe virtual interface basics that are relevant
+to the driver (VLANs, MGMT etc are not.) It should explain the use of
+the add_iface/remove_iface callbacks as well as the interface
+configuration callbacks.
+
+Things related to AP mode should be discussed there.
+
+Things related to supporting multiple interfaces should be in the
+appropriate chapter, a BIG FAT note should be here about this though and
+the recommendation to allow only a single interface in STA mode at
+first!
