Import rtw89 based on wireless-testing at (tag: wt-2022-09-02)
78667a29c116c6b186a37e28cd8dd7fa9923aee8 with adjustments for FreeBSD.
For the moment this will stay disconnected from the build until the
last bits are flushed out, but this will help people with a card to
do testing and possibly help improving.
Given the lack of full license texts on non-local files this is
imported under the draft policy for handling SPDX files (D29226). [1]

It was observed that on RockPro64 hardware, the dwc interface is unable
to receive packets after being assigned a new MAC address. The fix is
simply to call mii_mediachg() before touching any device registers in
dwc_init_locked(). This is consistent with what the OpenBSD driver does.

This enables attachment on the RPI4, thus enabling the bcm2835_pwm
driver too. Per the device tree documentation, these compat strings are
equivalent, and no further changes to the driver are required.

In doing some testing for a different problem, I have found rack retransmitting
all outstanding data every time a timeout occurs. The outstanding is sent 1ms
apart between each packet, and then the timeout runs off again. This causes
extra retransmissions when we should be waiting for an ack after sending the
very first segment.

There are drivers are using (*pause)(x, y) function pointers and depending
on how "pause" is used it gets replaced by pause_sbt causing compile time
failures.
Given "pause" is a generic enough name change it from a #define to an
inline function to avoid replacements where it should not.

The register map is fairly similar, with one difference in the local
sensor temperature register width.
Both devices support reading two sensors - "local" and "remote".
While here add support for the latter one.
The ADT7461 doesn't update the temperature correctly, unless a write
transaction is done before every read.
Do just that as a workaround for this issue.
Tested on LS1046ARDB.

Use the correct page size macro when checking if an address is with
the EFI runtime map. This would previously work correctly when the
page size is 4k. With a larger page size it may incorrectly detect
memory as within the map when it's not.

o Retire global always running ipreass_slowtimo().
o Instead use one callout entry per hash slot. The per-slot callout
would be scheduled only if a slot has entries, and would be driven
by TTL of the very last entry.
o Make net.inet.ip.fragttl read/write and document it.
o Retire IPFRAGTTL, which used to be meaningful only with PR_SLOWTIMO.

This call existed since pre-FreeBSD times, and it is hard to understand
why it was there in the first place. After 6f3caa6d81 it definitely
became necessary always and commit message from f1ee30ccd6 confirms that.
Now that 6f3caa6d81 is effectively backed out by 07285bb4c2, the call
appears to be useful only for sockets that landed on the incomplete queue,
e.g. sockets that have accept_filter(9) enabled on them.
Provide a new TCP flag to mark connections that are known to be on the
incomplete queue, and call soisconnected() only for those connections.

disk_blocks assumes BIOSDISK_SECSIZE, but the media may not be using

we end up with a short disk_blocks and subsequent validation fails when

On boot we cache the length the 'dc zva' instruction will zero. Use
this in the memset function to decide when to use it. As the cached
value is in .bss it will be zero on boot so memset is safe to use
before the value has been read.

Routing daemons such as bird need to know if they install certain route
so they can clean it up on startup, as a form of achieving consistent
state during the crash recovery.
Currently they use combination of routing flags (RTF_PROTO1) to detect
these routes when interacting via route(4) rtsock protocol.
Netlink protocol has a special "rtm_protocol" field that is filled and
checked by the route originator. To prepare for the upcoming netlink
introduction, add ability to record origing to both nexthops and
nexthop groups via <nhop|nhgrp>_<get|set>_origin() KPI. The actual
calls will be used in the followup commits.

In 8db2e8fd16 ("Remove the secondary_stacks array in arm64 [...]"),
bootstacks was setup to be allocated dynamically. While this is
generally how x86 does it, it inadvertently shrunk each boot stack from
KSTACK_PAGES pages to a single page.
Resize these back up to the expected size using the kstack_pages
tunable, as we'll need larger stacks with upcoming sanitizer work.

This corrects an issue introduced in b4cb3fe0e3, where a freshly
allocated `DOS_FS` structure would not be initialized properly before
use in `dos_open`.
In case of FAT32 file systems, this would leave `fs->dirents`
uninitialized and - depending on its content and due to checks in
`parsebs` - prevent mounting the file system successfully.
This particularily impacted the EFI loader, as it was sometimes not
able to read files from a FAT32-formatted EFI partition, including
LoaderEnv (`/efi/freebsd/loader.env`).
