12a89f0177 wifi: iwlwifi: remove 'use_tfh' config to fix crash
This is equivalent to 'gen2', and it was always confusing to have
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.

04f78e242f wifi: iwlwifi: mvm: Add support for IGTK in D3 resume flow
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.

1a528ab1da wifi: iwlwifi: mvm: avoid baid size integer overflow
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.

568db7fd27 wifi: iwlwifi: add some FW misbehaviour check infrastructure
When the firmware misbehaves (according to the driver), we
often either ignore that, or WARN_ON, which is very noisy
but doesn't really help.

Add a little helper macro IWL_FW_CHECK() that can be used
in place of WARN_ON() in conditions, and make it take a
message that's printed in this case. We can also add more
behaviour to this in the future.
