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:
link_elf_obj: symbol iwl_mvm_send_roaming_forbidden_event undefined

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.

Rather than having LinuxKPI return BUS_PROBE_DEFAULT, return

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)

Instead fix these locally, for ACPI_TO_INTEGER by simply casting the
incoming pointer to ACPI_SIZE (which corresponds roughly to uintptr_t
and size_t), and for ACPI_OFFSET by reusing our __offsetof definition
from sys/cdefs.h.

The ice(4) driver is the driver for the Intel E8xx series Ethernet
controllers; currently with codenames Columbiaville and
Columbia Park.
These new controllers support 100G speeds, as well as introducing
more queues, better virtualization support, and more offload
capabilities. Future work will enable virtual functions (like
in ixl(4)) and the other functionality outlined above.
For full functionality, the kernel should be compiled with
"device ice_ddp" like in the amd64 NOTES file, and/or
ice_ddp_load="YES" should be added to /boot/loader.conf so that
the DDP package file included in this commit can be downloaded
to the adapter. Otherwise, the adapter will fall back to a single
queue mode with limited functionality.
A man page for this driver will be forthcoming.

Although I added the reset type field to ath_hal_reset() years ago,
I never finished adding it both throughout the HALs and in if_ath.c.
This will eventually deprecate the ath_hal force_full_reset option
because it can be requested at the driver layer.
So:
* Teach ar5416ChipReset() and ar9300_chip_reset() about the HAL type
* Use it in ar5416Reset() and ar9300_reset() when doing a full chip reset
* Extend ath_reset() to include the HAL_RESET_TYPE parameter added in the above functions
* Use HAL_RESET_NORMAL in most calls to ath_reset()
* .. but use HAL_RESET_BBPANIC for the BB panics, and HAL_RESET_FORCE_COLD during fatal, beacon miss and other hardware related hangs.
This should be a glorified no-op outside of actual hardware issues.
I've tested things with ath_hal force_full_reset set to 1 for years now,
so I know that feature and a full reset works (albeit much slower than
a warm reset!) and it does unwedge hardware.
The eventual aim is to use this for all the places where the driver
detects a potential hang as well as if long calibration - ie, noise floor
calibration - fails to complete. That's one of the big hardware related
things that causes station mode operation to hang without easy recovery.

Yes, people shouldn't use bitfields in C for structure parsing.
If someone ever wants a cleanup task then it'd be great to remove them
from this vendor code and other places in the ar9285/ar9287 HALs.
Alas, here we are.
AH_BYTE_ORDER wasn't defined and neither were the two values it could be.
So when compiling ath_ee_print_9300 it'd default to the big endian struct
layout and get a WHOLE lot of stuff wrong.
So:
* move AH_BYTE_ORDER into ath_hal/ah.h where it can be used by everyone.
* ensure that AH_BYTE_ORDER is actually defined before using it!
This should work on both big and little endian platforms.
Ok, yeah, the commit title is a bit misleading.
This has to do with CDD (cyclic delay diversity) - how this and later
wifi hardware transmits lower rates over more antennas. Eg, if you're
transmitting legacy 11abg rates on 2 or 3 antennas, you COULD just
send them all at the same time or you could delay each by tens/hundreds
of nanoseconds to try and get some better diversity characteristics.
However, this has a fun side effect - the antenna pattern is no longer
a bunch of interacting dipoles, but are a bunch of interacting dipoles
plus a bunch of changing phases. And it's frequency dependent - 50-200nS
is not exactly the same fraction of a wavelength across all of 2GHz or 5GHz!
Thus the power spectral density and maximum directional gain that you're
effectively getting is not .. well, as flat as it once was.
For more information, look up FCC/OET 13TR1003 in the FCC technical report
database. It has pretty graphics and everything.
Anyway, the problem lies thusly - the CDD code just subtracts another 3dB
or 5dB for the lower rates based on transmit antenna configuration.
However, it's not done based on operating configuration and it doesn't
take into account how far from any regulatory limits the hardware is at.
It also doesn't let us do things like transmit legacy rates and frames
on a single antenna without losing up to 5dB when we absolutely don't
need to in that case (there's no CDD used when one antenna is used!)
This shows up as the hardware behaving even worse for longer distance links
at 20MHz because, well, those are the exact rates losing a bunch more
transmit power.
* For lower power NICs (ie the majority of what is out there!) it's highly
unlikely we're going to hit anywhere near the PSD limits.
* It's doing it based on the existing limits from the CTL table (conformance
testing limits) - this isn't the regulatory max! It's what the NIC is
allowed to put out in each frequency and rate configuration! So things like
band edges, power amplifier behaviour and maximum current draw apply here.
Blindly subtracting 3 to 5dB from /this/ value is /very/ conservative..
* /and/ ath9k just plainly doesn't do any of this at all.
So, for now disable it and get the TX power back, thus matching what ath9k
in Linux is doing. If/once I get some more cycles I'll look at making it
a bit more adaptive and really only kick in if we're a few dB away from
hard regulatory limits.
Tested:
* AR9344 (2GHz + SoC, 2x2 configuration) - AP and STA modes
* QCA9580 (5GHz 2x2 and 3x3 configurations) - AP and STA modes
