c4302c0f2d wifi: iwlwifi: mvm: always update keys in D3 exit 
If during D3 there was both a GTK rekey and a
disconnection, when waking up, we must first
update the new keys and then disconnect.

The reason is that when disconnecting we first need
to remove the keys.
Trying to remove invalid keys results in firmware
assert.

1b3741ea40 wifi: iwlwifi: mvm: limit pseudo-D3 to 60 seconds 
With unlimited pseudo-D3, we can get stuck here in the read if
the firmware never wakes up. All of our testing infrastructure
however will anyway give up after at most a minute, so there's
no value in that.

Limit this to about a minute to avoid getting stuck with the
RTNL held forever, which basically makes the machine unusable
and then we can't even understand what caused the failure.

f05ef3497f wifi: iwlwifi: mvm: fix the key PN index 
When waking from D3 (and a GTK rekey happened during
D3), the key itself is saved in iwl_wowlan_status_data::gtk
array, but the PN is saved in iwl_wowlan_status_data::gtk_seq
array.
The indices (of the same key) might differ in both arrays.
Fix using the gtk array index in the gtk_seq array.
Rather, iterate and search for the correct key in the
gtk_seq array.

556c7cd721 wifi: iwlwifi: properly check if link is active 
Before sending SESSION PROTECTION cmd the driver verifies that the
link for which the cmd is going to be sent is active.
The existing code is checking it only for MLD vifs,
but also the deflink (in non-MLD vifs) needs to be active in order
the have a session protection for it.
Fix this by checking if the link is active also for non-MLD vifs

74f4cd7107 wifi: iwlwifi: take SGOM and UATS code out of ACPI ifdef 
The BIOS tables SGOM and UATS are read from UEFI, but require
additional tables (WGDS and DSM func 3, respectively) which used to be
read from ACPI only, so the code handling those tables had to be under
ifdef ACPI. But now the driver reads those tables (WGDS and DSM) from

21c3f8f955 wifi: mac80211: refactor STA CSA parsing flows 
The new Wi-Fi Standard (IEEE Std 802.11-2020 9.4.2.160) specifies that
the Wide Bandwidth Channel Switch (WBCS) Element subfields have the same
definitions as VHT operation information if the operating band is not
S1G.

The problem comes when the BSS is in 6 GHz band, the STA parses the WBCS
Element by ieee80211_chandef_vht_oper(), which checks the capabilities for
HT/VHT mode, not HE/EHT mode.

This patch refactors STA CSA parsing flow so that the corresponding
capabilities can be checked. Also, it adds the way to use op_class in ECSA
Element to build a new chandef.

In summary, the new steps for STA to handle CSA event are:
1. build the new chandef from one of the CSA-related (Sub)Elements in
   following order,
   - Bandwidth Indication (Sub)Element
   - Wide Bandwidth Channel Switch (Sub)Element
   - Operating class in Extended Channel Switch Announcement Element
   - Channel Switch Announcement Element
2. convert the new chandef into operation information according to the
   operating band in order to check if the new chandef fits STA's
   capabilities.
3. downgrade the bandwidth until current bandwidth is not disabled.

37c37096ad wifi: mac80211: don't use sband->band early 
Some drivers may (notably mt76 does) not set up sband->band
before registering, and cfg80211 will fill it in later. But
since the HT/HE capability check mac80211 required it to be
initialized already, otherwise failing things.  This really
isn't necessary though since the code is iterating the list
of bands, and has the 'band' variable available.  Fix it to
not require the sband->band to be initialized already.

91cdcbbcde wifi: mac80211: clarify vif handling in TX dequeue 
The vif pointer at least looks like it can actually be NULL
in some cases such as the monitor-mode vif, causing static
checkers to complain with the immediate derefence. In these
cases the sta pointer will also be NULL, but clarify it in
the code anyway.

07095d1677 wifi: mac80211: start building elements in SKBs 
The building of elements is really mess, and really the only
reason we're not doing it in SKBs in the first place is that
the scan code in ieee80211_build_preq_ies() doesn't.

Convert ieee80211_build_preq_ies() to use an SKB internally
so that we can gradually convert other things to ..._put_*()
style interfaces.

6239da18d2 wifi: mac80211: adjust EHT capa when lowering bandwidth 
If intending to associate with a lower bandwidth, remove capabilities
related to 320 MHz from the EHT capabilities element. Also change the
EHT MCS-NSS set accordingly: if just reducing 320->160 or similar the
format doesn't change, just cut off the last bytes. If changing from
higher bandwidth to 20 MHz only EHT STA, adjust the format.

Note that this also requires adjusting the caller in mlme.c since the
data written can now be shorter than it determined. We need to clean
all that up. Since the other callers pass NULL for the conn limit, we
don't need to change things there.
