  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>

  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

 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.

 245           This chapter shall contain information on getting a hw

 247         </para>
 248         <para>
 249           Since it is required to allocate rates/modes before registering
 250           a hw struct, this chapter shall also contain information on setting
 251           up the rate/mode structs.
 252         </para>
 253         <para>
 254           Additionally, some discussion about the callbacks and
 255           the general programming model should be in here, including
 256           the definition of ieee80211_ops which will be referred to
 257           a lot.
 258         </para>
