Allow working IBSS also when working in DQA mode.
This is done by setting it to treat the queues the

This is a static analysis fix. The warning is:
drivers/net/wireless/intel/iwlwifi/mvm/fw-dbg.c:912 iwl_mvm_fw_dbg_collect()
warn: integer overflows 'sizeof(*desc) + len'
I guess this code is supposed to take a NUL character, but if we write
zero bytes then it tries to write -1 characters and crashes.

When a station is asleep, the fw will set it as "asleep".
All queues that are used only by one station will be stopped by
the fw.
In pre-DQA mode this was relevant for aggregation queues. However,
in DQA mode a queue is owned by one station only, so all queues
will be stopped.
As a result, we don't expect to get filtered frames back to
mac80211 and don't have to maintain the entire pending_frames
state logic, the same way as we do in aggregations.
The correct behavior is to align DQA behavior with the aggregation
queue behaviour pre-DQA:
- Don't count pending frames.
- Let mac80211 know we have frames in these queues so that it can
properly handle trigger frames.
When a trigger frame is received, mac80211 tells the driver to send
frames from the queues using release_buffered_frames.
The driver will tell the fw to let frames out even if the station
is asleep. This is done by iwl_mvm_sta_modify_sleep_tx_count.

The race happens when we send ADD_STA(auth->assoc) -> LQ_CMD
between the commands the FW sometimes loses the medium for AUX, and
sends a ndp to the AP and the flow becomes, ADD_STA -> send ndp -> LQ_CMD
the problem is that there's no rates yet defined for sending the ndp and
FW generates an assert.
The fix: change the order of the commands to LQ_CMD -> ADD_STA

The session protection set for association is only removed when
BSS_CHANGED_BEACON_INFO is set and BSS_CHANGED_ASSOC is not set.
However, mac80211 may set both on association (in case a beacon was
already received). In this case, mac80211 will not set
BSS_CHANGED_BEACON_INFO on the next beacons because it has already
notified the beacon change, so the session protection is never removed
(until the session protection ends).
When a CSA is received within this time, the station will fail to
folllow the channel switch because it cannot schedule the time event.
Fix this by removing the session protection when
BSS_CHANGED_BEACON_INFO and BSS_CHANGED_ASSOC are both set.

In https://bugzilla.kernel.org/show_bug.cgi?id=177341 Bob
reported a UBSAN WARNING on rs.c in iwldvm.
Fix the same bug in iwlmvm.
This because
i = index - 1;
for (mask = (1 << i); i >= 0; i--, mask >>= 1)
is unsafe: i could be negative and hence we can call <<
on a negative value.
This bug doesn't have any real impact since the condition
of the for loop will prevent any usage of mask.

In DQA mode, first_agg_queue is initialized to
IWL_MVM_DQA_MIN_DATA_QUEUE. This causes two bugs in the tx response
flow:
1. When TX fails, we set IEEE80211_TX_STAT_AMPDU_NO_BACK regardless
if we actually have aggregation open on the queue. This causes
mac80211 to send a BAR frame even though there is no aggregation
open.
Fix that by simply checking the AMPDU flag that is set on by
mac80211 for AMPDU packets.
2. When reclaiming frames in aggregation mode, we reclaim based on
scheduler ssn and not the SN.
The reason is that scheduler ssn may be ahead of SN due to a hole
in the BA window that was filled.
However, if we have aggregations open on IWL_MVM_DQA_BSS_CLIENT_QUEUE
the reclaim flow will still go to the code of non-aggregation
instead of the aggregation code since IWL_MVM_DQA_BSS_CLIENT_QUEUE
is smaller than IWL_MVM_DQA_MIN_DATA_QUEUE, although it is a valid
aggregation queue.
Fix that by always using the aggregation reclaim code by default in
DQA mode (currently it is implicitly used by default for all queues
except the reserved BSS queue).

In DQA mode the check whether to decrement the pending frames
counter relies on the tid status and not on the txq id.
This may result in an inconsistent state of the pending frames
counter in case frame is queued on a non aggregation queue but
with this TID, and will be followed by a failure to remove the
station and later on SYSASSERT 0x3421 when trying to remove the
MAC.
Such frames are for example bar and qos NDPs.
Fix it by aligning the condition of incrementing the counter
with the condition of decrementing it - rely on TID state for
DQA mode.
Also, avoid internal error like this affecting station removal
for DQA mode - since we can know for sure it is an internal
error.

A few of the static queues are enabled along with the bcast
STA. Make sure they are removed along with it, rather than
waiting for the mac ctxt release.
This is needed because we sometimes have a STA being removed
and then added again (either with the same sta_id or a
different one). If we wait for the mac ctxt release we will
try to allocate the queues again (as this is currently done
in the STA allocation and not in the MAC init) although
they weren't freed, and even if the sta_id of the STA has
changed.

Instead of setting the tx_cmd length in the mvm code, which is
complicated by the fact that DQA may want to temporarily store
the SKB on the side, adjust the length in the PCIe code which
also knows about this since it's responsible for duplicating
all those headers that are account for in this code.
As the PCIe code already relies on the tx_cmd->len field, this
doesn't really introduce any new dependencies.
To make this possible we need to move the memcpy() of the TX
command until after it was updated.
This does even simplify the code though, since the PCIe code
already does a lot of manipulations to build A-MSDUs correctly
and changing the length becomes a simple operation to see how
much was added/removed, rather than predicting it.

We don't really need clear the skb's status area nor store the
dev_cmd into it until we really commit to the frame by handing
it to the transport - defer those operations until just before
we do that.
This doesn't entirely fix the bug with frames not getting sent
out after having been deferred due to DQA, because it doesn't
restore the info->driver_data[0] place that was already set to
zero (or another value) by the A-MSDU logic.

The firmware will soon actually look at the AID field, and
when it does that it'll try to ensure that the AID is never
changing. Due to the way the station is added, it may start
with an invalid AID before it's associated, so to ensure a
constant AID (once it becomes non-zero), track the station
state and set the AID only when the station is associated
and when it disassociates.

This fixes a long-standing bug that was introduced when this code
was introduced: cfg80211 passes a pointer, but we treat it as if
it was passing a value. The result is that we pass the pointer to

ever have worked, unless the firmware is ignoring this value.

When driver needs to access the contents of a streaming DMA buffer
without unmapping it it should call dma_sync_single_for_cpu().
Once the call has been made, the CPU "owns" the DMA buffer and can
work with it as needed.
Before the device accesses the buffer, however, ownership should be
transferred back to it with dma_sync_single_for_device().
Both calls weren't performed by the driver, resulting with odd paging
errors on some platforms. Fix it.

For a000 devices the INIT and RT images are unified to one
image.
The changes in the flow are the following:
* Driver load only RT firmware - meaning that the nvm access
command will be done in the RT image load flow.
* A new command (NVM_ACCESS_COMPLETE) now signals to the FW that
the driver is done accessing the NVM and FW can proceed with phy
calibrations.
* Phy DB is no longer sent from INIT FW to be restored by driver
for the RT FW - all the phy DB is now internal to the FW.
INIT complete will now follow the NVM access command, without
phy DB calls before.
* Paging command is sent earlier in the flow before NVM access
to enable a complete load of FW.
* caution must be care when restart is called since we may have
not completed init flow even though we are in RT firmware.
