Since iwl_fw_error_collect() is now always called with the sync
argument set to true, to collect data synchronously, remove the
argument from it entirely.

In order to later add the ability to do deeper resets of the
device when it crashes, first restructure the firmware error
handling. Instead of having just a single nic_error() method
that handles all, split it:
- nic_error() just handles and prints the error itself,
- dump_error() synchronously creates an error dump, and
- sw_reset() will be called to request doing a SW reset.
This changes the architecture so that the transport is now
responsible for deciding how to do the reset, and therefore
the handling of reprobe if error occurs during reconfig
moves there, which necessitates adding a method there that
notifies the transport that the recovery was completed.
Actually introducing the model under which deeper resets can
be done will be in future patches.

When some channel context manipulations fail, the device
is going to be restarted to try to recover. Make this go
through a real FW restart via an NMI so the transport is
aware of it and can later handle escalation, and to make
it easier to restructure the code later.

Except for some special handling in DVM, error dump and some

now. Unify by giving a special error type, so DVM can continue

Approximately three years ago, in commit ddb6b76b6f96
("iwlwifi: yoyo: support TLV-based firmware reset"), the code
was (likely erroneously) changed to no longer treat error
interrupts as firmware errors. As a result, this meant that
the fw_restart counter was only applied in case of command
queue being stuck, which never seems to happen. Also, there's
no longer any way to set the mvm->fw_restart to a value that
doesn't match exactly the module parameter behaviour.
Instead of trying to fix this, simply remove the logic that
limits the number of restarts, it's clearly unused.
However, restore the logic that restart isn't unconditional,
by checking the module parameter.
Since the "fw_error" argument to iwl_mvm_nic_restart() is now
always true (except in the "never happens" case of CMD queue
stuck), just remove it too and treat command queue stuck the
same way as everything else.

This variable exists for the "common" (WiFi/BT) GUID, not the

A short-cut for the wifi-only version remains so not all code

Due to the firmware allocating the BAID, we can only install
the data structure after the BAID is valid from the firmware's
point of view. As a result, the firmware can start sending
frame release notifications to the driver immediately. This
isn't supposed to happen by protocol, since the peer STA is
not expected to use the blockack session until the AddBA has
a response. However, firmware doesn't know that, our RX path
can't know when it was, so simply don't WARN in this case but
only have a debug message.
Since the BAID comes from firmware, also use IWL_FW_CHECK()
instead of a warning for the validity check.

Instead of differentiating only sync/async, differentiate
the type of error, and document that only reset handshake
timeout (IWL_ERR_TYPE_RESET_HS_TIMEOUT) needs sync handling.
The special sync handling is somewhat temporary, the idea
is to later split the nic_error() method into error dump,
synchronizing the dump, and SW reset methods, and the type
is mostly in order to unify command queue full handling
into that new architecture as well.

shall carry a basic multi-mink element of that MLD in the frame body
of the multi-link probe response, whose location is outside of the

Therefore additional handing is needed for parsing multi-link probe
response and generating the merged elements so that the MLD in the frame

Currently, the sequence goes like this (among others):
1. flush all stations (including the AP ones) -> this will tell the
drivers to remove the stations
2. notify the driver the vif is not associated.
Which means that in between 1 and 2, the state is that the vif is
associated, but there is no AP station, which makes no sense, and may be
problematic for some drivers (for example iwlwifi)
Change the sequence to:
1. flush the TDLS stations
2. move the AP station to IEEE80211_STA_NONE
3. notify the driver about the vif being unassociated
4. flush the AP station
In order to not break other drivers, add a vif flag to indicate whether
the driver wants to new sequence or not. If the flag is not set, then
things will be done in the old sequence.

when it might actually be something else, causing us to skip all
the keys.
Since the call to iwl_mvm_sec_key_remove_ap was mostly skipped (because
for STA mode we are not removing the ap sta immediately, but later when
the vif is set to unassocicated),
this was fine.
The other call to iwl_mvm_sec_key_remove_ap, when we actually do remove the
ap sta, was called with the right link id. So the bug didn't happen so far.
Now that mac80211 is going to change such that we can immediately
remove the ap sta, the call to iwl_mvm_sec_key_remove_ap with link id 0
will not be skipped, so no key will be removed, and then when
mac80211 eventually tells us to remove that keys, we no longer have the
sta ids for them.
Simply pass the right link id to iwl_mvm_sec_key_remove_ap.

This code is only relevant for older devices, that are not supporting
mld, so shouldn't be in iwl_mvm_sta_del, which is common to both pre-mld

The intention here is not clear but as this was already tested and matches
vendor driver it's better not to change behavior even if it looks suspicious.

There is a specific error path in probe functions in wilc drivers (both
sdio and spi) which can lead to kernel panic, as this one for example
when using SPI:

The issue can easily be reproduced, for example by not wiring correctly
a wilc device through SPI (and so, make it unresponsive to early SPI
commands). It is due to a recent change decoupling wiphy allocation from
wiphy registration, however wilc_netdev_cleanup has not been updated
accordingly, letting it possibly call wiphy unregister on a wiphy which
has never been registered.
Fix this crash by moving wiphy_unregister/wiphy_free out of
wilc_netdev_cleanup, and by adjusting error paths in both drivers
