Add support Intel AX211 BZ MACs paired WiFi 6e RFs to iwx(4).
These devices are found in recent laptops using Intel AX211 WiFi 6e.
Only WiFi 6e, not WiFi 7, which will probably need a separate driver
as the Linux kernel does (iwlmld).
Firmware for BZ devices is available in fw_update.
There is still an unsolved problem with Tx performance. As soon as Tx
aggregation is used the device stalls and stops sending and receiving.
Tx performance is stable with block ack disabled, i.e. in mode 11a/b/g.
Help with figuring out the root cause of this would be appreciated.
I would have preferred to commit a fully working version but have
already spent quite a lot of time trying to find this last bug. It is
time to put this in anyway and hope the issue will be fixed soon.
Thanks to all involved for the support with review and testing of the
diffs which led up to this, to Johannes Berg for help with solving
various fatal firmware errors, to denis@'s company for making it

handle missed beacons notification sent by newer iwx(4) firmware
Newer firmware uses a new missed-beacons notification code in the
MAC_CONF group, but otherwise behaves as previously.
Check return values of fcntl(... O_CLOEXEC) calls by reusing the macro
in monitor.c. Flagged by Coverity CID 901297 in ssh-sk-client.c, a few
other instances added for good measure. begrudging ok deraadt@
Only enable MIMO on MLD iwx(4) devices if our AP supports MIMO.
Same approach as we are using for the pre-MLD device generation.
OK phessler@ kevlo@ jan@
Only add iwx(4) firmware PHY context once our channel is known.
The Linux iwlwifi driver no longer adds unused firmware PHY contexts
because newer firmware runs calibration when a PHY context is added.

Allow filters to prepend loglines with a priority tag. This way logmessages
can be written under a reasonable priority, instead of putting everything
under warning.
Current behaviour of tagless messages will still be written out under
warning.

Let smtpd write filter logging out to syslog under their own syslogtag.
This makes the layout more consistent with smtpd internal, and gives a
little more flexibility inside syslogd.
While here also document the user, group, and chroot arguments to a filter
as well.

Remove custom Rx A-MPDU reordering code from iwx(4).
The equivalent code was deleted from iwlwifi in 2023. It is only needed for
iwm 9k devices running with multiple Rx queues. AX200 and later devices do
Rx reordering in firmware and provide flags the driver can check to avoid
sending duplicate frames up the stack.

Prevent fatal firmware errors on iwx(4) Bz devices when forcing 11a/b/g mode.
Avoid enabling wide channels or MIMO in firmware Tx rate selection if we are
running in 11a/b/g mode.
Honour the "nomimo" network flag in any mode.

libsndio: Make sio_sun_xrun() backend-independent
The sio_sun_xrun() function uses only the sio_hdl field of the
structure passed as its first (and only) argument. Change the function
to take a sio_hdl pointer instead. This hides all audio(4)-specific
data and makes clear that the function is not related to the audio(4)
API.
No behavior change.
