      <para>
        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.
      </para>
      <para>
	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
  the first few sections to get a working driver and only advanced
  usage should require reading the full document.

    <part>
      <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>
      </partintro>

      <chapter id="basics">
        <title>Basic hardware handling</title>
        <para>TBD</para>
        <para>
          This chapter shall contain information on getting a hw
          struct allocated and registered with mac80211.
        </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.
