This should depend on both the RF (VHT/HE/EHT support) and
the MAC (<=22000 can put multiple frames into one buffer),
so unify the config in the struct iwl_cfg to just have it
sized according to the RF, and then double it for all the
MACs starting from AX210 (So/Ty).

In some older devices, the min/max firmware API supported by
the driver depends on the specific device, when sharing the
the same MAC (config). For most newer devices, it really is
dependent on the MAC instead, since the firmware was frozen
for certain MAC types. However, in the future we expect also
freezes for RF types there.
To handle this most generally, add an API min/max to the MAC
config and then use the narrowest range prescribed by both,
if set.
For the newer MACs since 9000, move the configuration, there
was only a freeze on MAC+RF lines so far.

There are a number of MAC parameters that are in the iwl_cfg
(which is the last config matched to the MAC/RF combination).
This isn't necessary, there are many more of those than MACs,
so move (most of) the data into the MAC family config struct.
Note that DCCM information remains for use by older devices,
and on 9000 series it'll be in struct iwl_cfg but be ignored
when the CRF is in a Qu/So platform.

These are (going to be) base MAC parameters that are identical
even for different platforms with the same MAC, so rename the
structure accordingly, calling it iwl_family_base_params.
Also rename the pointer to it so the dereferencing is a bit
shorter.

Since 9000 series devices, the devices are split into MAC and
CRF parts. Currently, "struct iwl_cfg" reflects some MAC and
some RF parameters, but we want to clean this up and move the
MAC data to what's now "struct iwl_cfg_trans_params". As the
first step, to reflect the intent, rename this structure.

A long time ago, when transport vs. device configs were
introduced, we wanted to eventually have a list of PCI
IDs and a separate list of devices, but for simplicity
embedded the transport config in the whole config, and
it all got confusing.
Finish splitting that out. Doing so requires having more
IWL_DEV_INFO() entries, but the whole trans/cfg aliasing
goes away and the code becomes a lot simpler.

The BW limit, cores and RF ID are matched in the subdevice ID,
so it doesn't really make sense to have both SUBDEV() match and
a match on any of those three. In particular, for Killer devices
the subdevice ID doesn't even follow the layout, so no matching
should be on those three values at all, only with SUBDEV().
Change the logic around the BW limit to have it more like all
the other things: only a bw_limit match in the dev_info, and
put the actual bandwidth into struct iwl_cfg. This duplicates a
number of those values, but that way the logic is clearer.
Add a test that checks that the three matches mentioned above
are not used in conjunction with SUBDEV(), and check that if
the bw_limit is matched, a BW limit is provided in the config.
Also check that the "Killer" devices have a SUBDEV() match.

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.

I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.

We're adding a new IWLMLD opmode for just BZ and later
devices. If that's enabled but IWLMVM isn't, the build
fails because 22000 family configs aren't built but BZ
and later refer to it. Rather than trying to make some
new file to build it in all cases, just copy the small
struct.
