==== mac80211 ====

mac80211 is a framework for writing %%SoftMAC%% drivers (see ''%%net80211(4)%%'' for %%FreeBSD%% counterpart). Its website at [[https://wireless.wiki.kernel.org/en/developers/documentation/mac80211|wireless.wiki.kernel.org]] has not been updated since 2015. The latest documentation is probably available in Linux 802.11 Driver Developer’s Guide. Most of the 802.11 standards should be implemented on the ''%%mac80211%%'' common %%SoftMAC%% layer.

Notes about mac80211 API (2015, outdated): https://wireless.wiki.kernel.org/en/developers/documentation/mac80211/api 

Interesting sequence diagrams: [[https://wireless.wiki.kernel.org/en/developers/documentation/mac80211/auth-assoc-deauth|1]] , [[https://wireless.wiki.kernel.org/en/developers/documentation/mac80211/hw-scan|2]] 

%%PaulFertser%% told me that if I really want to know how to use 802.11ac in Linux I should study the mac80211 driver for %%MediaTek%% MT76x2 802.11ac chips ([[https://github.com/openwrt/mt76]] ) as it is a relatively thin wrapper around real hardware functions in contrast to iwlwifi.

=== Johannes Berg's presentation ===

Johannes Berg's presentation (2009, Intel): https://wireless.wiki.kernel.org/_media/en/developers/documentation/mac80211.pdf \\ 
The most important mac80211 header to driver developers: ''%%include/net/mac80211.h%%''\\ 
Other files are in ''%%net/mac80211/%%''.

==== 802.11n and 802.11ac support for Intel hardware ====

https://wireless.wiki.kernel.org/en/users/drivers suggests that iwlwifi supports A/B/G/N/AC PHY modes.
