<!--
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.

      <para>TBD</para>
      <para>
        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.
      </para>
      <para>Things related to AP mode should be discussed there.</para>
      <para>
        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!
