=============================
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.
