To: Johannes Berg, Kalle Valo; +Cc: linux-wireless, ath11k, John Crispin
This series adds support for propagating the TWT and OBSS PD information
from userland/assocs to a wireless driver. The patches for making use of
these features inside ath11k are also included.
I already have the hostapd patches ready and will send them once these
changes are inside nl80211.h.
John Crispin (7):
mac80211: dynamically enable the TWT requester support on STA
interfaces
mac80211: allow turning TWT responder support on and off via netlink
ath11k: add TWT support
mac80211: HE: add Spatial Reuse IE parsing support
mac80211: allow setting spatial reuse parameters when bringing up an
AP
mac80211: propagate spatial reuse info into ieee80211_sta
ath11k: add spatial reuse support
