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.

PHY configuration
|
|
=================
|
|
|
|
TBD
|
|
|
|
This chapter should describe PHY handling including start/stop callbacks
|
|
and the various structures used.

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!

what should be here

TBD

|
|
drivers as well as transmit status handling.
