f2abe804e8 wifi: rtw89: 8852b: rfk: add IQK
IQ signal calibration is a very important calibration to yield good RF
performance. We do this calibration only if we are going to run on AP
channel. During scanning phase, without this calibration RF performance
is still acceptable because it transmits with low data rate at this phase.

RX DCK is receiver DC calibration. With this calibration, we have proper
DC offset to reflect correct received signal strength indicator. Do this
calibration when bringing up interface and going to run on AP channel.

2e82be13c6 wifi: mac80211: agg-rx: avoid band check
If the deflink of the station is on 6 GHz, then it won't have HT.
If at the same time we're using MLO, then vif.bss_conf isn't used,
and thus vif.bss_conf.chandef.chan is NULL, causing the code to
crash.

Fix this by just checking for both HT and HE, and refusing the
aggregation session if both are not present. This might be a bit
wrong since it would accept an aggregation session from a peer
that has HE but no HT on 2.4 or 5 GHz, but such a peer shouldn't
exist in the first place, and it probably supports aggregation if
it has HE support.

9a886df0c3 wifi: mac80211: use link_id in ieee80211_change_bss()
We should set the parameters here per link, except
unfortunately ap_isolate, but we can't really change
that anymore so it'll remain a quirk in the API in
that you need to change it on one of the valid links
and it'll apply to all.

We clearly need the link ID here, to know the right BSS
to configure. Use/require it.

f7ee304111 wifi: mac80211: transmit AddBA with MLD address
This management frame is intended for the MLD so we
treat it in mac80211 as MLD addressed as well, and
should therefore use the MLD address of the AP for
the BSSID field in the frame, address translation
applies.

2d5e617149 wifi: mac80211: wme: use ap_addr instead of deflink BSSID
We use this to look up the destination station, so it
needs to be the MLD address of the AP for an MLO; use
ap_addr instead of the BSSID.

c2d052a3c4 wifi: mac80211: Process association status for affiliated links
In case the AP returned a non success status for one of the links,
do not activate the link.
