We also have some docs available:

https://docs.kernel.org/driver-api/80211/

And I also recommend looking at our hwsim driver as that gives a good
idea how a simple mac80211 driver works:

https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next.git/tree/drivers/net/wireless/virtual/mac80211_hwsim.c

And you can even tinker the driver and run tests without needing any
real hardware:

https://docs.kernel.org/networking/mac80211_hwsim/mac80211_hwsim.html

And if there are any questions about mac80211 or anything wireless
related please send them to linux-wireless. Usually someone will answer
as long the question is well formulated.
