In preparation for future updates remove the budget argument from the
netif_napi_add() in drivers and update LinuxKPI to reflect that it is
gone and only set it internally. This required changes to the currently
committed wireless drivers based on LinuxKPI (iwlwifi, rtw88, rtw89).

f808c43ad9 introduced a FreeBSD specific
behaviour to wait for firmware load completion before returning from
loading the driver. This does no longer allow iwl_drv_stop to detect
that startup has completed and it will wait indefinitely for a
completion event that will not happen.
We could change the complete() call to a complete_all() but to avoid
confusion, future side effects, and for simplicity daisy-chain two
complete events in FreeBSD.

Import two files left out initially from the driver needed for debugfs
support [1]. Adjust the driver further to make it compile on FreeBSD.
This is currently turned off and needs more LinuxKPI/lindebugfs work.
Being in the tree will allow us to collaboratively work on it and
then we can enable it for good.

iwlwifi can return early from probe (in FreeBSD attach) while a separate
thread is still grinding loading the firmware and setting things up.
For us this means that kldload succeeded but we may not have a physical
wireless interface (com) yet but the rc framework might already try to
configure a vap on one.
Wait until we get a firmware completion event from the other thread
(on success or error) and block returning. That way we can ensure that
the "hw" (or com in net80211 terms) is there when we return from attach
matching the expected FreeBSD driver behaviour.

Update the mac80211 ops KPI for (*conf_tx), (*assign_vif_chanctx),
(*unassign_vif_chanctx), (*start_ap), and (*stop_ap), as well as
ieee80211_beacon_get_tim() and ieee80211_beacon_get_template().
Update in-tree drivers iwlwifi and rtw88 accordingly based on upstream

synchronize more drivers to a common state.

For one initialise vif->hw_queues later set in lkpi_80211_txq_tx_one()
for drivers using them. This may still need slightly more cleanup once
we get QUEUE_CONTROL-supporting drivers into the tree.
For the other rework and improve how we deal with tid/ac/txq in
lkpi_80211_txq_tx_one() and cleanup old comments and unused code.
This seems to reduce (remove) "Invalid TXQ id" reports from iwlwifi.
(The assumption is that the frame(s) triggering this WARN_ONCE or the
added FreeBSD specific logging were sent with lkpi_80211_mo_tx()).
Adjust the one logging from e674ddec0b
to IWL_DEBUG_TX so that now this is fixed it is also not always logged
anymore but leave it in case we need to further debug queues in the
future.

Introduce a local change. It seems ieee80211_get_tid() does not deal
with non-dataqos packets unlike net80211's ieee80211_gettid().
Gernally all calls in Linux drivers to ieee80211_get_tid() seem to
be proceeded by an ieee80211_is_data_qos() check.
Moving the ieee80211_get_tid() has no difference in the result, but
(a) saves us the call if we do not need it due to an earlier return,
and (b) allows us to put an assert into the LinuxKPI ieee80211_get_tid()
implementation to avoid accidentally returning random frame header data
in case of a missing earlier ieee80211_is_data_qos() check in (future/
other) drivers.

"Invalid TXQ id" and "Queue <n> is stuck <x> <y>" are two errors seen
more commonly by FreeBSD users. Try to gather some extra data the
"easy way" adding more error logging for these situations in the hope
to find a clue or at least do more targetd debugging in the future.
Note that for one of the errors the Linux Intel driver has a TODO to
print register data. If that will show up in future versions of the
driver this may also help.

It is unclear why this hasn't bothered anyone in months; I can only assume
optimization levels but it seems there were unresolved symbols in
iwlwifi after d9836fb4b9:

Add a FreeBSD-specifc SYSCTL_PROC to dump the list of
PCI IDs / name / firmware-prefix which can be post-processed
for man pages (iwlwifi.4 and iwlwififw.4) or the wiki.
The output still yields duplicates depending on by what information
you need so one may wants to filter them out (try not to use sort/uniq).

Working on an update for rtw88 baed on wireless-testing I ran into
a build issue with struct ieee802211_sta. Some fields were factored
out into their own struct apparently preparing for MLO (Multi Link
Operation).
In order to be able to update one driver we have to adjust both
rtw88 and iwlwifi (and the ones still out-of-tree) now.
This is mostly a sed-replace job and no functional changes are
intended.

This amongst other things removes the deprecated BCAST_FILTERING option,
which we had disabled before due to firmware issues.
Also prepares us for the next firmware update.
The "enable_ini" module option has become an integer with a
sysctl proc equivalent handler. Disable the module parameter changing
for the moment until we'll have working LinuxKPI support or implement
it as SYSCTL_PROC in FreeBSD directly.

Rather than having LinuxKPI return BUS_PROBE_DEFAULT, return
"one less" so that on conflict of IDs others would be preferred.
This means that iwm(4) will attach instead of iwlwifi(4) for the
chipsets iwm(4) supports and iwlwifi(4) only for the other--in iwm(4)
unsupported--chipsets. This is done so that we can enable auto-loading
of drivers but for the upcoming 13.1-Release people with working iwm(4)
will not yet be affected by iwlwifi(4).

Also add files not previously imported because we are not yet compiling
them to ease updating and having them when needed.
This adds MEI (Management Engine) support upstream which we cannot import
(currently GPL-only) so we have stub functions for the missing bits.
This also reduces the diff to upstream. Changes submitted to avoid
problems with const and with void * arithmetics were merged.
In the module build Makefile disable CONFIG_IWLWIFI_OPMODE_MODULAR

In certain situations we saw a memory modified after free. This was
tracked down to a pointer not NULLed after free and used in a different
code path. It is unclear how the race happens pending further

Over the past few months we published multiple snapshots for this
Linux derived driver and it has become fairly stable in terms of
minimal local changes needed for new updates.
The current version is based on iwlwifi-next update at
cbaa6aeedee5f92dafa5982eceea2a1f98ce4f7d with the addition of
a hand full of files replaced for FreeBSD.
Given the lack of full license texts on non-local files this is
imported under the draft policy for handling SPDX files (D29226). [1]
Do not yet hook this to the build until the remaining compat code
is all in. Along with the firmware import this will make publishing
the last bits and final testing a lot easier.
