mac80211: add documentation book
Quite a while ago I started this book. The required kernel-doc patches have since gone into the tree so it is now possible to build the book in mainline. The actual documentation is still rather incomplete and not all things are linked into the book, but this enables us to edit the documentation collaboratively, hopefully driver authors can add documentation based on their experience with mac80211.

61Generally, this document shall be ordered by increasing complexity.
62It is important to note that readers should be able to read only
63the first few sections to get a working driver and only advanced
64usage should require reading the full document.
65-->
66
67 <part>
68 <title>The basic mac80211 driver interface</title>
69 <partintro>
70 <para>
71 You should read and understand the information contained
72 within this part of the book while implementing a driver.
73 In some chapters, advanced usage is noted, that may be
74 skipped at first.
75 </para>
76 <para>
77 This part of the book only covers station and monitor mode
78 functionality, additional information required to implement
79 the other modes is covered in the second part of the book.

82
83 <chapter id="basics">
84 <title>Basic hardware handling</title>
85 <para>TBD</para>
86 <para>
87 This chapter shall contain information on getting a hw
88 struct allocated and registered with mac80211.
89 </para>
90 <para>
91 Since it is required to allocate rates/modes before registering
92 a hw struct, this chapter shall also contain information on setting
93 up the rate/mode structs.
94 </para>
95 <para>
96 Additionally, some discussion about the callbacks and
97 the general programming model should be in here, including
98 the definition of ieee80211_ops which will be referred to
99 a lot.
100 </para>
101 <para>
102 Finally, a discussion of hardware capabilities should be done
103 with references to other parts of the book.

143 Things related to supporting multiple interfaces should be
