Subject: [PATCH 1/5] nl80211: add basic multiple bssid support
This patch adds support for passing the multiple bssid config to the
kernel when adding an AP gets started. If the BSS is non-transmitting we
need to pass the ifidx of the transmitting parent. The multiple bssid
elements are passed as an array inside the beacon data. This allows use
to generate multiple bssid beacons aswell as EMA ones.

Subject: [PATCH 2/5] mac80211: add multiple bssid support to interface
handling
When bringing up multi bssid APs we need to track the parent-child
relation aswell as figuring out if the BSS is (non-)transmitting.
The new helper function ieee80211_set_multiple_bssid_options() takes
care of storing the config as well as figuring out the runtime flags of the
virtual interface.
The patch also makes sure that when a parent is closed, its children are
also closed.

Subject: [PATCH 3/5] mac80211: add multiple bssid/EMA support to beacon
handling
With beacon_data now holding the additional information about the
multiple bssid elements, we need to honour these in the various beacon
handling code paths.
Extend ieee80211_beacon_get_template() to allow generation of multiple
bssid/EMA beacons. The API provides support for HW that can offload the
EMA beaconing aswell as HW that will require periodic updates of the
beacon template upon completion events.
In case the HW can do full EMA offload, functions are provided that
allow the driver to get a list of the periodicity number of beacons and
their matching mutable offsets.

Subject: [PATCH 4/5] mac80211: don't allow CSA on non-transmitting interfaces
As a non-transmitting interface does not broadcast a beacon, we do not
want to allow channel switch announcements. They need to be triggered
on the transmitting interface.

Subject: [PATCH 5/5] ath11k: add EMA support
This patch adds EMA support to mac80211/EMA. Currently the patch will
crash the FW.
The RFT is aimed at the QCA team to help debug the FW crash.
