    <abstract>

      <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.
