Now that the fw_name_mac is no longer around and derived
from the MAC type automatically, we no longer need to have
different configurations for Qu/QuZ. Combine them. For the
killer AX1650s/i, also fix the names, there was a mixup.

The IWL_DEV_INFO() macro has far too many arguments, and most
of the time they're just "ANY". Use C99 initializers in the

iwlwifi is the driver of all Intel wifi devices since 2008.
Since then, the hardware has changed a lot, but the firmware
API has changed even more. The need to keep one driver that
supports all those different APIs led us to introduce a new
architecture circa 2012 which allowed us to keep the same
interface to the hardware (DMAs, Tx queues, etc...) with a
new layer to implement the mid-layer between mac80211 and
the firmware. The first component is called the 'transport'
and the latter is called 'operation_mode' a.k.a op_mode.
In 2013 we took advantage of the new architecture to
introduce iwlmvm which allowed us to implement the, then,
new firmware API. This op_mode supports 7260 and up, those
devices supports support at least VHT.
Since then, wifi evolved and so did the firmware. It became
much bigger and took a lot of functionality from the driver.
It became increasingly hard to keep the same op_mode for the
newest devices and we experienced frequent regressions on
older devices. In order to avoid those regressions and keep
the code maintainable, we decided it was about time to start
a new op_mode.
iwlmld is a new op_mode that supports BE200 or newer if the
firmware being used is 97.ucode or newer. If the user has
an older devices or BE200 with .96.ucode, iwlmvm will be
loaded. Of course, this op_mode selection is seamless.
All the features supported in iwlmvm are supported in
iwlmld besides a few seldom used use cases: injection and
Hotspot 2.0. Those are under work.
A few points about the implementation:
* iwlmld doesn't have any mutexes, it relies on the
wiphy_lock
* iwlmld is more "resource oriented": stations, links and
interfaces are allocated and freed only after all the
relevant flows are completed.
* Firmware notifications' sizes are validated in a more
structured way.
We would love to see this new op_mode merged in 6.15. The
firmware for this new driver (.97.ucode) is not yet publicly
available but it'll be sent very soon.
People eager to get an early version of this firmware can
contact Emmanuel at:
emmanuel.grumbach@intel.com
I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.

We'll have devices that are EHT capable but don't support 320 MHz and
those devices look like the 320 MHz capable devices, but have distinct
subsystem ID.
We already had the same type of differentiation for HE devices that
support 160 MHz or not.
Enhance that mechanism and now the _IWL_DEV_INFO macro gets an
indication whether the bandwidth should be limited for that specific
device.
The subsystem ID gives a binary answer about the bandwidth limitation
and iwl_pci_find_dev_info() compares this to the list of _IWL_DEV_INFO
entries.

The TOP is a shared (between BT and WiFi) hardware component,
and if it has an error we need to reset the whole device, i.e.
both BT and WiFi. This is achieved by calling a specific ACPI
DSM (device-specific method) with the right arguments before
doing a reset via the object referenced by _PRR.
Since this is needed here, but a function reset will always do
better than just re-enumerating the bus in case of errors, we
can always try to at least do a function reset and do the full
product reset only when needed for TOP errors.
Also, for some Bz and Sc devices where BT is PCIe/IOSF as well,
find the BT device and unbind that device as well so the BT
driver can recover from the reset that's going to happen,
rather than having to somehow detect that the device was reset.
Also add - currently unused - the function reset mode, this is
going to get used in the upcoming escalation model.

Fast resume is a feature that was recently introduced to speed up the
resume time. It basically keeps the firmware alive while the system
is suspended and that avoids starting again the whole device.
This flow can't work for hibernation, since when the system boots,
before the frozen image is loaded, the kernel may touch the device. As a
result, we can't assume the device is in the exact same state as before
the hibernation.
Detect that we are resuming from hibernation through the PCI device and
forbid the fast resume flow. We also need to shut down the device
cleanly when that happens.
In addition, in case the device is power gated during S3, we won't be
able to keep the device alive. Detect this situation with BE200 at least
with the help of the CSR_FUNC_SCRATCH register and reset the device upon
resume if it was power gated during S3.

Split the configuration list in 22000.c into four new files,

still much better than what we have now.

If a discrete NIC is connected to a PCIe link hat isn't at least
Gen3 (8.0 GT/s), then we cannot sustain 320 MHz traffic, so remove
that from EHT capabilities in that case.
While at it, also move setting 320 MHz beamformee to the right
place in the code so it's not set while not supporting 320 MHz.

The original implementation checked the HW family, and as a result
of that used different addresses for the prph registers.
The old HWs addresses start with 0xa****** and the newer
ones start with 0xd******.
For this there are iwl_read/write_umac_prph functions that just add the
diff in the address automatically (in this case 0x300000), so the code will
be common for all HWs
In the original implementation the address given already had the 0xd******
causing the address to become 0x10***** (after adding the offset)
Change the registers to start with 0xa*****.

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.)

iwlmei needs to know about the follwing events:
* Association
* De-association
* Country Code change
* SW Rfkill change
* SAR table changes
iwlmei can take the device away from us, so report the new
rfkill type when this happens.
Advertise the required data from the CSME firmware to the
usersapce: mostly, the AP that the CSME firmware is currently
associated to in case there is an active link protection
session.
Generate the HOST_ASSOC / HOST_DISSASSOC messages.
Don't support WPA1 (non-RSNA) for now.
Don't support shared wep either.
We can then determine the AUTH parameter by checking the AKM.
Feed the cipher from the key installation.
SW Rfkill will be implemented later when cfg80211 will
allow us to read the SW Rfkill state.

Both gcc-11 and clang point out a potential issue with integer overflow when
the iwl_dev_info_table[] array is empty. This is what clang warns:

This is still harmless, as the loop correctly terminates, but adding
an extra range check makes that obvious to both readers and to the

Sometimes some NICs may fail to initialize, but if we have
such a scenario we may only see an alive timeout (i.e. the
firmware doesn't send us the alive message), and that will
only cause us to fail the interface up.
Try to once grab NIC access during device probe to ensure
we can properly talk to the hardware at all, and to do all
the potential workarounds in that function.
Since we now finish NIC init here, we can remove it from
the later potential read of the RF ID.

When having a blank OTP the only way to get the rf id
and the cdb info is from prph registers.
Currently there is some implementation for this, but it

and it has a partial implementation.
