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>
59 <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".

218 Generally, this document shall be ordered by increasing complexity.

225 <title>The basic mac80211 driver interface</title>
226 <partintro>

228 You should read and understand the information contained

230 In some chapters, advanced usage is noted, that may be
231 skipped at first.
232 </para>
233 <para>
234 This part of the book only covers station and monitor mode

236 the other modes is covered in the second part of the book.

248 Since it is required to allocate rates/modes before registering
249 a hw struct, this chapter shall also contain information on setting
250 up the rate/mode structs.
251 </para>

253 Additionally, some discussion about the callbacks and
254 the general programming model should be in here, including
255 the definition of ieee80211_ops which will be referred to

135 This chapter should describe virtual interface basics
136 that are relevant to the driver (VLANs, MGMT etc are not.)
137 It should explain the use of the add_iface/remove_iface
138 callbacks as well as the interface configuration callbacks.

142 Things related to supporting multiple interfaces should be
143 in the appropriate chapter, a BIG FAT note should be here about
144 this though and the recommendation to allow only a single
145 interface in STA mode at first!
