			get_tx_stats() driver operation is not currently used anywhere in mac80211 and there are no plans to use it in the not-so-near future. So it can go without anyone missing it.

|     <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>
 | |
|         This chapter shall contain information on getting a hw

 | |
|       </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 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.
