-Subject: [PATCH] nl80211: add support for BSS coloring
-
-This patch adds support for BSS color collisions to the wireless subsystem.
-Add the required functionality to nl80211 that will notify about color
-collisions, triggering the color change and notifying when it is completed.

-Subject: [PATCH] mac80211: add support for BSS color change
-
-The color change announcement is very similar to how CSA works where
-we have an IE that includes a counter. When the counter hits 0, the new
-color is applied via an updated beacon.
-
-This patch makes the CSA counter functionality reusable, rather than
-implementing it again. This also allows for future reuse incase support
-for other counter IEs gets added.

-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.
