Subject: [PATCH] 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.
