f81747a9ad wifi: mac80211: handle wider bandwidth OFDMA during CSA 
During channel switch, track the AP configuration in the
chanreq, so that wider bandwidth OFDMA is taken into
account correctly, since multiple channel contexts may
be needed due to sharing not being possible due to
wider bandwidth OFDMA.

7ef8f6821d wifi: mac80211: mlme: handle cross-link CSA 
If we see a channel switch announcement on one link for
another, handle that case and start the CSA. The driver
can react to this in whatever way it needs. The stack
will have the ability to track it via the RNR/MLE in the
reporting link's beacon if it sees it for inactive links
and adjust everything accordingly.

Note that currently the timings for the CSA aren't set,
the values are only used by the Intel drivers, and they
don't need this for newer devices that support MLO, so
I've left it out for now.

Also, improve the check whether operating (carrier

If during that 30 seconds EMLSR was blocked and unblocked

7aea718037 wifi: iwlwifi: mvm: simplify the uAPSD coexistence limitation code 
uAPSD can't be enabled on BSS or P2P Client if there is
another active interface (e.g. associated client). Allow
the code that apply those limitations to run on BSS as well.
Also forbid uAPSD if we have an IBSS or NAN interface in
the system.
Since we are now forbidding uAPSD in any concurrency
scenario, we don't need to check the number of PHY
contexts.

32fca7e382 wifi: iwlwifi: dvm: clean up rs_get_rate() logic 
The logic here is rather convoluted - we cannot get here with
lq_sta being NULL as mac80211 will (no longer) call us like
that, and since I removed the rate_control_send_low() call in
this function there's no longer any point in setting priv_sta
to NULL either.

So the only thing that remains to check is if we have actually
initialized our lq_sta->drv pointer, and exit if we didn't in
which case we'll use the data mac80211 already set up for the
low rate usage.

39dc8b8ea3 wifi: mac80211: pass parsed TPE data to drivers 
Instead of passing the full TPE elements, in all their glory
and mixed up data formats for HE backward compatibility, parse
them fully into the right values, and pass that to the drivers.

Also introduce proper validation already in mac80211, so that
drivers don't need to do it, and parse the EHT portions.

The code now passes the values in the right order according to
the channel used by an interface, which could also be a subset
of the data advertised by the AP, if we couldn't connect with
the full bandwidth (for whatever reason.)

Also add kunit tests for the more complicated bits of it.

The chanctx can be shared, but it seems like the TPE values for

is captured in bss_conf->chanreq.oper rather than the chanctx.
Use that when calculating defaults, a similar issue is where the
data from the AP is processed, but I'm moving that to mac80211.

Remove IEEE80211_MAX_NUM_PWR_LEVEL and, for ath11k being
