mac80211 subsystem (advanced)
|
|
=============================
|
|
|
|
Information contained within this part of the book is of interest only
|
|
for advanced interaction of mac80211 with drivers to exploit more
|
|
hardware capabilities and improve performance.
|
|
|
|
LED support
|
|
===========
|
|
|
|
Mac80211 supports various ways of blinking LEDs. Wherever possible,
|
|
device LEDs should be exposed as LED class devices and hooked up to the
|
|
appropriate trigger, which will then be triggered appropriately by
|
|
mac80211.

|
|
addresses here, note which configurations are supported by mac80211, add
|
|
notes about supporting hw crypto with it.
