[00/12] Additional support for 802.11ah (S1G)

Message

Kieran Frewen July 11, 2022, 1:08 a.m. UTC

This patchset builds on the work down by Thomas Pedersen to add further
support for 802.11ah in cfg80211 and mac80211. The ultimate goal is
to enable the successful starting of an AP on 802.11ah using 802.11ah
terms by implementing the various features that are required by the
AP. The features are split into their own commits, please see those
patches for more details.

The patchset has been tested on both real hardware (Morse Micro MM610x)
and mac80211_hwsim, in AP and STA modes. Basic regression testing was
performed on 802.11n with mac80211_hwsim by starting an AP and having a
STA interface connect to it.

802.11ah features/support missing:
 - Rate control integration
 - Regulatory database updates (only US regulatory information exists)
 - Optional 802.11ah (S1G) features such as RAW, TWT and AID grouping

  mac80211: update TIM for S1G specification changes
