`#ifndef WITHOUT_CAPSICUM` is left in the source for the benefit of

Several users with alc(4)-based "Killer" Ethernet cards have reported
issues with this driver not passing traffic, which are solved by
disabling MSI-X using the provided tunable.
To work around this issue, disable MSI-X by default on this card.
This is done by having msix_disable default to 2, which means
"auto-detect". The user can still override this to either 0 or 1 as
desired.
Since these are slow (1Gbps) Ethernet ICs used in low-end systems, it's
unlikely this will cause any practical performance issues; on the other
hand, the card not working by default likely causes issues for many new
FreeBSD users who find their network port doesn't work and have no idea
why.

- Remove superfluous whitespace by removing trailing whitespace
before `\` (line continuation character)
- Quote `SUBDIR.` to clarify the fact that this is a variable
reference--not the end of a sentence.
When in netmap (emulated) mode, wireguard interfaces prepend or strip a
dummy ethernet header when interfacing with netmap. The netmap
application thus sees unencrypted, de-encapsulated frames with a fixed
header.
In this mode, netmap hooks the if_input and if_transmit routines of the
ifnet. Packets from the host TX ring are handled by wg_if_input(),
which simply hands them to the netisr layer; packets which would
otherwise be tunneled are intercepted in wg_output() and placed in the
host RX ring.
The "physical" TX ring is processed by wg_transmit(), which behaves
identically to wg_output() when netmap is not enabled, and packets
appear in the "physical" RX ring by hooking wg_deliver_in().

As discussed in bug 278417, some ports require the F16C instruction set
to compile, but there is no way yet to detect whether the currently
chosen CPUTYPE supports this feature.
Add the feature to the MACHINE_CPU variable, for each processor that
supports it. The list of processors was extracted from clang 18's -dM

Now that the handbook has been moved to ports, I think it's very nice to
have a network quickstart guide in-band, in base, in the system manual.
If the user uses any of the following terms "man -k

think a very common use case for new users.

Following the convention used in the rest of this file, ${LIBPFCTLDIR}
should refer to the directory, and ${LIBPFCTL} to the library itself.
Instead, both values were assigned to ${LIBPFCTL}, and ${LIBPFCTLDIR} was
not set at all.
This appears to be a simple typo and not a deliberate choice, so fix it
by assigning the directory name to ${LIBPFCTLDIR} instead.

Hot-unplugging a sound device, such as a USB sound card, whilst being
consumed by an application, results in an infinite loop until either the
application closes the device's file descriptor, or the channel
automatically times out after hw.snd.timeout seconds. In the case of a
detach however, the timeout approach is still not ideal, since we want
all resources to be released immediatelly, without waiting for N seconds
until we can use the bus again.
The timeout mechanism works by calling chn_sleep() in chn_read() and
chn_write() (see pcm/channel.c) in order to send the thread to sleep,
using cv_timedwait_sig(). Since chn_sleep() sets the CHN_F_SLEEPING flag
while waiting for cv_timedwait_sig() to return, we can test this flag in
pcm_unregister() (called during detach) and wakeup the sleeping
thread(s) to immediately kill the channel(s) being consumed.

Currently the snd_clone framework creates device nodes on-demand for
every channel, through the dsp_clone() callback, and is responsible for
routing audio to the appropriate channel(s). This patch gets rid of the
whole snd_clone framework (including any related sysctls) and instead
uses DEVFS_CDEVPRIV(9) to handle device opening, channel allocation and
audio routing. This results in a significant reduction in code size as
well as complexity.
Behavior that is preserved:
- hw.snd.basename_clone.
- Exclusive access of an audio device (i.e VCHANs disabled).
- Multiple processes can read from/write to the device.
- A device can only be opened as many times as the maximum allowed
channel number (see SND_MAXHWCHAN in pcm/sound.h).
- OSSv4 compatibility aliases are preserved.
Behavior changes:
Only one /dev/dspX device node is created (on attach) for each audio
device, as opposed to the current /dev/dspX.Y devices created by
snd_clone. According to the sound(4) man page, devices are not meant to
be opened through /dev/dspX.Y anyway, so it is best if we do not create
device nodes for them in the first place. As a result of this, modify
dsp_oss_audioinfo() to print /dev/dspX in the "ai->devnode", instead of
/dev/dspX.Y.

As mentioned in zpoolprops(7), on some SSDs, it may not be desirable to
use ZFS autotrim because a large number of trim requests can degrade
disk performance; instead, the pool should be manually trimmed at
regular intervals.
Add a new daily periodic script for this purpose, 801.trim-zfs. If
enabled (daily_trim_zfs_enable=YES; the default is NO), it will run a
'zpool trim' operation on all online pools, or on the pools listed in
'daily_trim_zfs_pools'.
The trim is not started if the pool is degraded (which matches the
behaviour of the existing 800.scrub-zfs script) or if a trim is already
running on that pool. Having autotrim enabled does not inhibit the
periodic trim; it's sometimes desirable to run periodic trims even with
autotrim enabled, because autotrim can elide trims for very small
regions.

This adds support for two new diff algorithms, Myers diff and Patience

These algorithms perform a different form of search compared to the
classic Stone algorithm and support escapes when worst case scenarios
are encountered.
Add the -A flag to allow selection of the algorithm, but default to
using the new Myers diff implementation.
The libdiff implementation currently only supports a subset of input and
output options supported by diff. When these options are used, but the
algorithm is not selected, automatically fallback to the classic Stone
algorithm until support for these modes can be added.
