| <!-- | |
| 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> | |
