24c776355f kernel.h: drop hex.h and update all hex.h users
Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of
hex.h interfaces to directly #include <linux/hex.h> as part of the process
of putting kernel.h on a diet.

Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.

This change has been build-tested with allmodconfig on most ARCHes.  Also,
all users/callers of <linux/hex.h> in the entire source tree have been
updated if needed (if not already #included).

d1ee2c1922 wifi: iwlwifi: mld: only create debugfs symlink if it does not exist
When mac80211 switches between non-MLO and MLO it will recreate the
debugfs directories. This results in the add_if_debugfs handler being
called multiple times. As the convenience symlink is created in the mld
debugfs directory and not the vif, it will not be removed by mac80211
when this happens and still exists.

Add a check and only create the convenience symlink if we have not yet
done so.

8301e2636c wifi: iwlwifi: mld: Ensure wiphy lock is held during debugfs read operations
The WIPHY_DEBUGFS_READ_WRITE_FILE_OPS_MLD macro is intended to call
read/write handlers with the wiphy lock held. However, the current
implementation uses the MLD_DEBUGFS_READ_WRAPPER macro, which does
not hold the wiphy lock during read operations. This fix updates
the WIPHY_DEBUGFS_READ_WRITE_FILE_OPS_MLD macro to use the
WIPHY_DEBUGFS_READ_WRAPPER_MLD macro instead, ensuring that the
wiphy lock is held during both read and write operations.

d1e879ec60 wifi: iwlwifi: add iwlmld sub-driver
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.
