cac9544cec wifi: iwlwifi: mvm: replace CONFIG_PM by CONFIG_PM_SLEEP 
Replace the ifdef CONFIG_PM by CONFIG_PM_SLEEP. CONFIG_PM was useful
when we had CONFIG_PM_RUNTIME but that was removed long ago.
Use PM_SLEEP consistently across the driver.

a032b5fc24 wifi: iwlwifi: mvm: properly set the rates in link cmd 
When a channel ctx is assigned to a link, we set the
LINK_CONTEXT_MODIFY_RATES_INFO to indicate that the rate fields are now
valid. But then we always take the rates of 2.4 GHz regardless of actual
used band.
This is because we are getting the band from bss_conf->chanctx_conf, but
this is assigned only after drv_assign_vif_chanctx returns, so we take
the bands of 2.4 GHz.
Fix it by taking the band from the iwl_mvm_link_info::phy_ctxt instead,
as this has already assigned in this point.

07fb53783b wifi: iwlwifi: mvm: tell the firmware about CSA with mode=1 
When we de-activate a link because it started a CSA with mode=1, we want
to tell the firmware it can no longer transmit any frame for that link.
The firmware will do that on its own if the CSA indication (beacon /
action frame) was  received on that same link, but with MLO, things got
more complex and the firmware can't track cross link CSA.

Tell the firmware if we de-activate a link because of CSA with mode=1 to
prevent it from transmitting, even if it is only an NDP PM=1 frame that
is part of the de-activation flow.

557a6cd847 wifi: iwlwifi: mvm: avoid NULL pointer dereference 
iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta
pointer is not NULL.
It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is
dereferencing the ieee80211_sta pointer.
If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL
pointer.
Fix this by checking the sta pointer before retrieving the mvmsta
from it. If sta is not NULL, then mvmsta isn't either.

1c7e1068a7 wifi: iwlwifi: mvm: drop wrong STA selection in TX 
This shouldn't happen at all, since in station mode all MMPDUs
go through the TXQ for the STA, and not this function. There
may or may not be a race in mac80211 through which this might
happen for some frames while a station is being added, but in
that case we can also just drop the frame and pretend the STA
didn't exist yet.

Also, the code is simply wrong since it uses deflink, and it's
not easy to fix it since the mvmvif->ap_sta pointer cannot be
used without the mutex, and perhaps the right link might not
even be known.

Just drop the frame at that point instead of trying to fix it
up.

b2a7c91bf9 wifi: iwlwifi: mvm: Offload RLC/SMPS functionality to firmware 
Currently, the driver handles SMPS decisions by tracking AP
capabilities, BT coexistence changes, sending necessary SMPS
frames to the AP, and updating firmware with RX chain info
using the RLC_CONFIG_CMD.

Starting with version 3 of the RLC_CONFIG_CMD, the firmware
takes over this responsibility. It now tracks SMPS, sends
frames, and configures the RLC.

In this patch:
1. Stop sending RLC_CONFIG_CMD when firmware supports RLC
   offload (version 3), as rlc.rx_chain_info is not needed by
   firmware, and no other field in the cmd is used.
2. Prevent the driver from forwarding any SMPS requests to
   mac80211, i.e., the driver should not transmit SMPS frames
   to the AP as firmware handles that.
3. Set NL80211_FEATURE_DYNAMIC_SMPS and NL80211_FEATURE_STATIC_SMPS
   conditionally based on RLC version.

87c1c28a9a wifi: iwlwifi: mvm: Fix a race in scan abort flow 
When the upper layer requests to cancel an ongoing scan, a race
is possible in which by the time the driver starts to handle the
upper layers scan cancel flow, the FW already completed handling
the scan request and the driver received the scan complete
notification but still did not handle the notification. In such a
case the FW will simply ignore the scan abort request coming from
the driver, no notification would arrive from the FW and the entire
abort flow would be considered a failure.

To better handle this, check the status code returned by the FW for
the scan abort command. In case the status indicates that
no scan was aborted, complete the scan abort flow with success, i.e.,
the scan was aborted, as the flow is expected to consume the scan
complete notification.

094513f8a2 wifi: iwlwifi: clear trans->state earlier upon error 
When the firmware crashes, we first told the op_mode and only then,
changed the transport's state. This is a problem if the op_mode's
nic_error() handler needs to send a host command: it'll see that the
transport's state still reflects that the firmware is alive.

Today, this has no consequences since we set the STATUS_FW_ERROR bit and
that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording
looks at this bit to know not to send a host command for example.

To fix the hibernation, we needed to reset the firmware without having
an error and checking STATUS_FW_ERROR to see whether the firmware is
alive will no longer hold, so this change is necessary as well.

Change the flow a bit.
Change trans->state before calling the op_mode's nic_error() method and
check trans->state instead of STATUS_FW_ERROR. This will keep the
current behavior of iwl_fw_dbg_stop_restart_recording upon firmware
error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording
safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not
alive.

3a84454f52 wifi: iwlwifi: mvm: don't wait for tx queues if firmware is dead 
There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.

Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.
