wifi: iwlwifi: use default command queue watchdog timeout
We used to have the opmode configuring it to the trans according to the
debug tlv value (FW_DBG_TRIGGER_TXQ_TIMERS).
But this debug is not used, so trans can just have the default value
hardcoded.

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.

wifi: iwlwifi: release TXQ lock during reclaim
Much of the work during reclaim can be done without holding the TXQ

Add a new reclaim_lock to prevent parallel cleanup. Release the lock
while working with an internal copy of the txq->read_ptr and only take
the lock again when updating the read pointer after the cleanup is done.

wifi: iwlwifi: pcie: integrate TX queue code
The TX queue code was mostly moved out to support an internal
transport that we were never going to publish, but we're no
longer using that. Since we're also going to be dissolving
the virtual transport layer entirely, integrate the TX queue
code into the PCIe layer.
This also has a small kernel of already removing the virtual
transport function layer, since iwl_trans_send_cmd() calls
iwl_trans_pcie_send_hcmd() directly now, even if that still
calls the transport send_cmd method for now, we'll clean it
up later.
Also, not everything is renamed yet.

wifi: iwlwifi: empty overflow queue during flush
If a TX queue has no space for new TX frames, the driver will keep
these frames in the overflow queue, and during reclaim flow it
will retry to send the frames from that queue.
But if the reclaim flow was invoked from TX queue flush, we will also
TX these frames, which is wrong as we don't want to TX anything
after flush.
This might also cause assert 0x125F when removing the queue,
saying that the driver removes a non-empty queue
Fix this by TXing the overflow queue's frames only if we are
not in flush queue flow.

wifi: iwlwifi: disable multi rx queue for 9000
Multi rx queue allows to spread the load of the Rx streams on different
CPUs. 9000 series required complex synchronization mechanisms from the
driver side since the hardware / firmware is not able to provide
information about duplicate packets and timeouts inside the reordering
buffer.
Users have complained that for newer devices, all those synchronization
mechanisms have caused spurious packet drops. Those packet drops
disappeared if we simplify the code, but unfortunately, we can't have
RSS enabled on 9000 series without this complex code.
Remove support for RSS on 9000 so that we can make the code much simpler
for newer devices and fix the bugs for them.
The down side of this patch is a that all the Rx path will be routed to
a single CPU, but this has never been an issue, the modern CPUs are just
fast enough to cope with all the traffic.

wifi: iwlwifi: Take loading and setting of pnvm image out of parsing part
Change iwl_pnvm_parse so it will only save the information into the
iwl_pnvm_image struct. This enables to use the parsing code for the
power reduce tables in the future.

wifi: iwlwifi: Separate loading and setting of pnvm image into two functions
Take the part that is copying the pnvm image into DRAM, out of the
the method that sets the prph_scratch. Makes the code cleaner since
those 2 operations don't always happen together (loading should happen
only once while setting can happen more than once).
In addition, each operation will get more complex in the future when
it will support also larger pnvm images.

wifi: iwlwifi: Generalize the parsing of the pnvm image
Generalize iwl_pnvm_parse(). This saves us from copying each payload
twice (first in the parsing and later when copying it to the dram).
Moreover, its more compatible for handling larger pnvm tables in
the future (in which payloads won't be concatenated).
The main changes are:
1. Take out the concatenating of the payloads from the parsing level
2. Start using iwl_pnvm_image structure that will hold pointers to
payloads that should be delivered to fw, their sizes and number.

iwlwifi: support new queue allocation command
Newer firmware versions will support a new queue allocation
command, in order to deal with MLD where multiple stations
are used for a single queue. Add support for the new command.
This requires some refactoring of the queue allocation API,
which now gets
- the station mask instead of the station ID
- the flags without the "enable" flag, since that's no longer
used in the new API
Additionally, this new API now requires that we remove queues
before removing a station, the firmware will no longer do that
internally. Also add support for that.

iwlwifi: support 4-bits in MAC step value
We have a MAC component (which is inside the SoC) and it has several
different HW steps. 3 bits used to be enough but now we need 4-bits
to represent all the different steps.
Properly support 4-bits in the MAC step value by refactoring all the
current handling of the MAC step/dash.
Already from family 8000 and up the dash (bits 0-1) no longer exists
and the step (until 8000 bits 2-3) consists of the dash bits as well.
To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH
macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step
into the trans struct.
In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and
CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro
combining the 2 (this way we don't need shifting or anything else.)

iwlwifi: fw dump: add infrastructure for dump scrubbing
In firmware dumps, currently all kinds of key material may be
included, e.g. in host commands (if firmware crashes during the
processing of a key-related command) or in the TX FIFO(s) if
we have been using in-TX-command key material.
Additionally, some firmware versions will advertise sections
of their internal data to not dump, due to them containing some
sensitive data.
Add some infrastructure to allow scrubbing this data out, as
dependent on the opmode's idea of what will need to be done.
