At least ath11k needs an extra FW call to enable TWT inside the HW. This
series adds code to trigger this from within start_ap() and also STA assoc
events.
Changes in V2
* fix 2 typos
* move from bbs_config to start_ap
John Crispin (3):
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
