The management frames protection flag is always set when the station
is not yet authorized. However, it was not cleared after association
even if the association did not use MFP. As a result, all public
action frames are not parsed by fw (which will cause FTM to fail,
for example). Update the station MFP flag after the station is
authorized.

set_antenna() is supported only when the device is not started in
mac80211 which translates to the firmware not being loaded in iwlwifi.
The tricky part is that iwlwifi populates the sband data during its boot
and doesn't touch this data afterwards, but if the antenna settings
forbid MIMO, we need to update the sband data.
Rework the nvm parsing code to allow to get an existing nvm_data and
modify the sband with additional constraints (tx / rx chains masks).

If the firmware crashes in the de-activation / re-activation
of the link during CSA, we will not have a valid phy_ctxt
pointer in mvmvif. This is a legit case, but when mac80211
removes the station to cleanup our state during the
re-configuration, we need to make sure we clear ap_sta
otherwise we won't re-add the station after the firmware has
been restarted. Later on, we'd activate the link, try to send
a TLC command crash again on ASSERT 3508.
Fix this by properly cleaning up our state.

Currently we are setting the rate in the tx cmd for
mgmt frames (e.g. during connection establishment).
This was problematic when sending mgmt frames in eSR mode,
as we don't know what link this frame will be sent on
(This is decided by the FW), so we don't know what is the
lowest rate.
Fix this by not setting the rate in tx cmd and rely
on FW to choose the right one.
Set rate only for injected frames with fixed rate,
or when no sta is given.
Also set for important frames (EAPOL etc.) the High Priority flag.

If the channel bandwidth is greater or equal than 80MHz,
enable FILS DF transmittion, even if the control channel is non-PSC.
That's because that in 80MHz there must be a sub 20MHz PSC
channel, and since the FILS DF is duplicated on all sub 20MHz
channels, within the 80MHz (hence it will be sent on a PSC channel).
Also, if FILS DF Tx is enabled, always configure the firmware
with the actual channel bandwidth, even before there is a connected
client (rather than the minimum bandwidth e.g. 20MHz), since FILS
DF transmission on a PSC channel take presedent over power
consumption.

If the device initialized with ME active, this would indeed
work, since the NVM information would be obtained from ME.
However, in the much more likely case that ME isn't active
and the firmware takes actions requiring the sync, this was
not working correctly when the firmware is only run at init
to obtain NVM data, since mac80211 isn't even initialized.
Fix this by moving the 'pldr_sync' handling to a different
place.

A few lines above, space is kzalloc()'ed for:
sizeof(struct iwl_nvm_data) +
sizeof(struct ieee80211_channel) +
sizeof(struct ieee80211_rate)
'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is fine.
At the end of this structure, there is the 'channels' flex array.
Each element is of type 'struct ieee80211_channel'.
So only 1 element is allocated in this array.
When doing:
mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels;
We point at the first element of the 'channels' flex array.
So this is fine.
However, when doing:
mvm->nvm_data->bands[0].bitrates =
(void *)((u8 *)mvm->nvm_data->channels + 1);
because of the "(u8 *)" cast, we add only 1 to the address of the beginning
of the flex array.
It is likely that we want point at the 'struct ieee80211_rate' allocated
just after.
Remove the spurious casting so that the pointer arithmetic works as
expected.

The firmware was trying to report the B2 RU allocation in
the place previously used here as well, but there's a HW
block that clears the lower 8 bits in this metadata word
even in sniffer mode. Thus, firmware moved B2 to another
place, follow that.
There's no need to detect the version since moving it to
the other place if firmware didn't just means that we'll
continue to report the (erroneous) zero value, and it's
not really something we can detect from the firmware now.
While debugging this we realized that the comments about
placement in the metadata dwords are wrong, update them.

In the spec, CSA is defined roughly as follows:
- TBTT x: beacon with CSA, count=n (old channel)
- TBTT x+1: beacon with CSA, count=n-1 (old channel)
- TBTT x+n-1: beacon with CSA, count=1 (old channel)
"A Channel Switch Count field set to 1 indicates that the switch
occurs immediately before the next TBTT.
- TBTT x+n: beacon without CSA (new channel)
When we detect it, we currently schedule the CSA event to
be at 10 TUs before TBTT x+n-1, for a beacon interval, to
give us quiet time.
When this event *starts*, we currently notify mac80211
that the channel switch happened, which causes us to add
a session protection event to listen for the first beacon
(and enable TX etc. when that arrives).
We don't even ask for a notification when this event ends
so the code that handles that is effectively dead code.
The session protection duration is 3 beacon intervals,
scheduled at 10 TU before TBTT x+n-1. It will thus end
just before TBTT x+n+2.
Unfortunately, if the AP doesn't transmit or we miss just
the first two beacons on the new channel, then this will
cause us to disconnect. Or even just one, if the AP isn't
quite aligned with the TBTT after the switch.
However, listening to the _end_ of the time event isn't
what we want either, because we want all the new PHY and
other config that needs to come from mac80211 to start
early, so we have a head-start for the new channel, since
we're not going to use the old one anyway for this time.
So since we don't really have anything better to do at
this time, and this is relatively rare, just make the
session protection use 5x the beacon interval instead of
just 3x, so it's more likely we catch a beacon even if
the AP neglected to send it, or we just miss it.

two identical config entries. The split config patch actually had
been originally developed after removing 'use_tfh" and didn't add
the use_tfh in the new configs as they'd later been copied to the
new files. Thus the easiest way to fix the init crash here now is
to just remove use_tfh (which is erroneously unset in most of the
configs now) and use 'gen2' in the code instead.
There's possibly still an unwind error in iwl_txq_gen2_init() as
it crashes if TXQ 0 fails to initialize, but we can deal with it
later since the original failure is due to the use_tfh confusion.

As part of the new security API in the FW, all security keys are to
be removed before station removal. Until now IGTK rekey
wasn't supported in the D3 resume flow, and thus the driver might
not know the right key to remove.
If an IGTK was rekeyed during D3 the old IGTK is removed and the
new key is updated. If not, the old key's IPN is updated.
As opposed to GTK, which both the FW and the driver hold it's two
most recent keys, only one IGTK is held.

When resuming from D3 the two most recent GTKs are passed from
the FW with wowlan_info_notif. Both keys should be updated as
they both might be needed upon FW restart and they both should
be removed upon station removal.

All the configurations for the various Bz/Gl devices
are basically identical, except for Gl A-step and the
firmware filename prefixes.
Add some infrastructure to auto-generate the firmware
filename prefix based on the detected MAC step and
RF name/step, and remove all the unneeded configs.
This reduces the size of the iwlwifi module by ~9k:

When hostapd starts up, it may start up with only one link
while the other is still scanning for overlapping BSSes. A
station might start to connect at this point, but we run
into this warning instead. Since there's no need to check
for _all_ links, restrict the check to just the affected
links that the STA will be using.

Roee reported various hard-to-debug crashes with pings in
EHT aggregation scenarios. Enabling KASAN showed that we
access the BAID allocation out of bounds, and looking at
the code a bit shows that since the reorder buffer entry
(struct iwl_mvm_reorder_buf_entry) is 128 bytes if debug
such as lockdep is enabled, then staring from an agg size
512 we overflow the size calculation, and allocate a much
smaller structure than we should, causing slab corruption
once we initialize this.
Fix this by simply using u32 instead of u16.
