===========================
mac80211 subsystem (basics)
===========================
You should read and understand the information contained within this
part of the book while implementing a mac80211 driver. In some chapters,
advanced usage is noted, those may be skipped if this isn't needed.
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.
Basic hardware handling
=======================
TBD
This chapter shall contain information on getting a hw struct allocated
and registered with mac80211.
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.
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.
Finally, a discussion of hardware capabilities should be done with
references to other parts of the book.

ieee80211_register_hw

PHY configuration
=================
TBD
This chapter should describe PHY handling including start/stop callbacks
and the various structures used.
.. kernel-doc:: include/net/mac80211.h
:functions:
ieee80211_conf
ieee80211_conf_flags
Virtual interfaces
==================
TBD
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.
Things related to AP mode should be discussed there.
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!
.. kernel-doc:: include/net/mac80211.h
:functions: ieee80211_vif
Receive and transmit processing
===============================
what should be here
-------------------
TBD
This should describe the receive and transmit paths in mac80211/the
drivers as well as transmit status handling.
