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.

fix to use ieee80211_get_he_iftype_cap() correctly]
