51       <para>
52         These books attempt to give a description of the
53         various subsystems that play a role in 802.11 wireless
54         networking in Linux. Since these books are for kernel
55         developers they attempts to document the structures
56         and functions used in the kernel as well as giving a
57         higher-level overview.
58       </para>
59       <para>
60         The reader is expected to be familiar with the 802.11
61         standard as published by the IEEE in 802.11-2007 (or
62         possibly later versions). References to this standard
63         will be given as "802.11-2007 8.1.5".

219   Generally, this document shall be ordered by increasing complexity.
220   It is important to note that readers should be able to read only
221   the first few sections to get a working driver and only advanced
222   usage should require reading the full document.

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

249           Since it is required to allocate rates/modes before registering

251           up the rate/mode structs.

254           Additionally, some discussion about the callbacks and
