013e516dc9 LinuxKPI: 802.11: fix iwlwifi fw assert with older chipsets
A problem which showed up on 13.1 between BETA3 and RC1 was that on older
chipsets the fw would crash.  While some 0x18 ADD_STA problems were seen
before, d9f59799fc was the actual trigger for this problem
(in 0x28 MAC_CONTEXT command) in a squashed merge to the releng branch.
Strangely there were no changes to assoc_to_run in that revision so other
circumstances may be the actual cause but swapping the bss_info update and
the sta_state in that function seem to make my 8265 happy while AX200 and
AX210 stay good.

Thanks to everyone who helped debug this.

d0d2911035 LinuxKPI: 802.11: rework handling of the special IEEE80211_NUM_TIDS queue
Rework the way we are dealing with the last queue.  If the driver
opts in to STA_MMPDU_TXQ then preferably send all non-data frames
via the last (IEEE80211_NUM_TIDS) queue which otherwise is not used
in station mode.
If we do not have that queue we do individual tx() calls for non-data
frames now.
Everything else goes via the selected queue if possible for as long as
we have a ni (sta) and otherwise resorts to direct tx.

0e981d79b1 LinuxKPI: move pm_message_t from kernel.h to pm.h
Move pm_message_t from kernel.h to pm.h and remove a private define
in usb.h as well as adjust the implementation in linux_usb.c.
This cleans up what I believe to be a historic shortcut and is
needed for future wireless driver updates.

Leave a note in UPDATING that drm-kmod users need to update to the
latest version before re-compiling a new kernel to avoid errors

the later does, is confusing.

99902b1c52 linuxkpi/dmi: don't match exactly on DMI_MATCH
Linux has two defines to check dmi data. DMI_MATCH checks if the dmi
string includes substr. DMI_EXACT_MATCH checks if the dmi string exactly
matches substr. Compat layer should have the same behaviour.

The new definition of dmi_strmatch shouldn't break any driver. A driver
would break if it uses the highest bit of the slot field. Nevertheless,
linux uses the same definition and FreeBSD uses dmi_field values as slot
which are lower than 128.

of a constant in the signal mask manipulation macro.
The suffix L indicates type long which is 32-bit on i386, therefore,
bitwise operations between a 32-bit constant and 64-bit signal mask
lead to the wrong result.

3a99aac66f linux(4): Check the socket before any others sanity checks
Strictly speaking, this check is performed by the kern_recvit(), but in
the Linux emulation layer before calling the kernel we do other sanity
checks and conversions from Linux types to the native types. This changes
an order of the error returning that is critical for some buggy Linux
applications.

For recvmmsg() syscall this fixes a panic in case when the user-supplied
vlen value is 0, then error is not initialized and garbage passed to the
bsd_to_linux_errno().

d46174cd88 Finish cpuset_getaffinity() after f35093f8

user_cpuset_getaffinity() is intended to operate on the cpuset_t from
user va, while kern_cpuset_getaffinity() expects the cpuset from kernel
va.
Accordingly, the code that clears the high bits is moved to the
user_cpuset_getaffinity(). Linux sched_getaffinity() syscall returns
the size of set copied to the user-space and then glibc wrapper clears
the high bits.

6cf748ad94 LinuxKPI 802.11 / iwlwifi / rtw88 : re-factor ieee802211_sta for MLO
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.
