4 Subject: [PATCH] mac80211: introduce individual TWT support in AP mode
5
6 Introduce TWT action frames parsing support to mac80211.
7 Currently just individual TWT agreement are support in AP mode.
8 Whenever the AP receives a TWT action frame from an associated client,
9 after performing sanity checks, it will notify the underlay driver with
10 requested parameters in order to check if they are supported and if there
11 is enough room for a new agreement. The driver is expected to set the
12 agreement result and report it to mac80211.
13
14 Drivers supporting this have two new callbacks:
15 - add_twt_setup (mandatory)
16 - twt_teardown_request (optional)
17
18 mac80211 will send an action frame reply according to the result
19 reported by the driver.

24 [use le16p_replace_bits(), minor cleanups, use (void *) casts,
25 fix to use ieee80211_get_he_iftype_cap() correctly]
