From f5a4c24e689f54e66201f04d343bdd2e8a1d7923 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Mon, 23 Aug 2021 20:02:39 +0200 Subject: mac80211: introduce individual TWT support in AP mode Introduce TWT action frames parsing support to mac80211. Currently just individual TWT agreement are support in AP mode. Whenever the AP receives a TWT action frame from an associated client, after performing sanity checks, it will notify the underlay driver with requested parameters in order to check if they are supported and if there is enough room for a new agreement. The driver is expected to set the agreement result and report it to mac80211. Drivers supporting this have two new callbacks: - add_twt_setup (mandatory) - twt_teardown_request (optional) mac80211 will send an action frame reply according to the result reported by the driver.
