4d08c0b335 wifi: iwlwifi: mvm: handle BA session teardown in RF-kill
When entering RF-kill, mac80211 tears down BA sessions, but
due to RF-kill the commands aren't sent to the device. As a
result, there can be frames pending on the reorder buffer or
perhaps even received while doing so, leading to warnings.

Avoid the warnings by doing the BA session teardown normally
even in RF-kill, which also requires queue sync.

cc3ba78f20 wifi: iwlwifi: mvm: remove stale STA link data during restart
If pre-recovery mac80211 tried to disable a link but this disablement
failed, then there might be a mismatch between mac80211 assuming the
link has been disabled and the driver still having the data around.
During recover itself, that is not a problem, but should the link be
activated again at a later point, iwlwifi will refuse the activation as
it detects the inconsistent state.

Solve this corner-case by iterating the station in the restart cleanup
handler.

8c73e8b595 wireless-next patches for v6.10
The first "new features" pull request for v6.10 with changes both in
 stack and in drivers. The big thing in this pull request is that
 wireless subsystem is now almost free of sparse warnings. There's only
 one warning left in ath11k which was introduced in v6.9-rc1 and will
 be fixed via the wireless tree.
 
 Realtek drivers continue to improve, now we have support for RTL8922AE
 and RTL8723CS devices. ath11k also has long waited support for P2P.
 
 This time we have a small conflict in iwlwifi as we didn't consider it
 as major enough to justify merging wireless tree to wireless-next. But
 Stephen has an example merge resolution which should help with fixing
 the conflict:
 
 https://lore.kernel.org/all/20240326100945.765b8caf@canb.auug.org.au/
 
 Major changes:
 
 rtw89
 
 * RTL8922AE Wi-Fi 7 PCI device support
 
 rtw88
 
 * RTL8723CS SDIO device support
 
 iwlwifi
 
 * don't support puncturing in 5 GHz
 
 * support monitor mode on passive channels
 
 * BZ-W device support
 
 * P2P with HE/EHT support

In the previous commit, I renamed the variable to differentiate
mac80211/mvm link STA, but forgot to adjust the check. The one
from mac80211 is already non-NULL anyway, but the mvm one can
be NULL when the mac80211 isn't during link switch conditions.
Fix the check.

8598826012 wifi: iwlwifi: mvm: assign link STA ID lookups during restart
When restarting the HW, mac80211 first adds the STA back with only one
link enabled. This means that iwl_mvm_alloc_sta_after_restart will not
see the other links and will not do the assignment.

As such, do the assignment when mac80211 is activating the link for the
station.

There are some assertions in the STA removal code that can

the freeing.

Fix this by freeing the dup_data earlier in the function,
we already have a check for when we free the station, and
this we don't need to do it with and without MLD API, so
it's a win all around.

84f650e632 wifi: iwlwifi: mvm: remove per-STA MFP setting
When we first add the STA before sending an authentication
frame this is false. However, in some cases such as FT or
certainly in MLO link switch scenarios, it will be true.

If it happens to be true, it causes a firmware assert (in
LMAC, 0x2528), because the same bit is used by the firmware
for tracking this setting as well as for tracking if the
management key has been installed, and then we get this
assert from the firmware when installing the MFP key as it
thinks it has already been installed.

Remove the setting for now, until the firmware disentangles
the two. We should be able to set it, in fact we should be
setting it speculatively before authentication/association,
to avoid processing management frames that should have been
protected/encrypted before the key is set.

881d054896 wifi: iwlwifi: mvm: fix station link data leak
When we remove the station, we call iwl_mvm_sta_del() which
returns true if we cannot remove it from the firmware yet,
which happens if this is the station ID for the AP station
that's still used because the MAC is still associated.

However, we still must free the link data as the station is
only kept alive in the firmware, in mac80211 and driver the
data structures are destroyed.

To fix that, we need to make iwl_mvm_mld_free_sta_link()
track whether or not the station is still alive in FW, as
otherwise we might reuse the station ID in the meantime and
iwl_mvm_mld_rm_sta_from_fw() would reject the later delete
from the firmware. Add an argument to it for that. Then we
can use the return value of iwl_mvm_sta_del() for that to
fix the issue, and call iwl_mvm_mld_rm_sta_from_fw() only
if we need to not keep the station in FW.
