Subject: [PATCH 2/3] mac80211: dynamically turn TWT requester support on and off
Date: Fri, 26 Apr 2019 10:42:43 +0200	[thread overview]
Message-ID: <20190426084244.28098-3-john@phrozen.org> (raw)
In-Reply-To: <20190426084244.28098-1-john@phrozen.org>

Turn TWT for STA interfaces when they associate and/or receive a
beacon where the twt_responder bit has changed.
