The FreeBSD shell is a POSIX compatible shell. It evolved over several
decades from the Almquist shell, which was preceeded a decade before
that by the Bourne shell. Most readers today have never seen a Bourne
shell. If someone wants to learn to use our shell, they need to look for
tutorials on the POSIX shell. Align descriptions through out the tree
with this reality, consistent with it's manual and common parlance.
We made a similar change to the doc tree in b4d6eb01540fe.

This example opens separate OSS capture and playback channels in mmap
mode, places them into a sync group, and starts them together so both
ring buffers advance on the same device timeline. It then monitors the
capture mmap pointer with SNDCTL_DSP_GETIPTR, converts that pointer into
monotonic absolute progress using the reported block count, and copies
newly recorded audio from the input ring to the matching region of the
output ring.
The main loop is driven by an absolute monotonic frame clock rather than
a fixed relative usleep delay. Wakeups are scheduled from the sample
rate using a small frame step similar to the SOSSO timing model, while
the audio path itself stays intentionally simple: just copy input to
output, with no explicit xrun recovery or processing beyond ring
wraparound handling.

Advertise IFCAP_WOL_MAGIC when PCI power management is available
and enable it by default. On suspend or shutdown, rge_setwol()
enables the WOL_MAGIC and WOL_LANWAKE bits in CFG3/CFG5, disables
the RXDV gate, and enables PM so the NIC stays powered to watch
for magic packets.
Move hardware-specific WOL register configuration into
rge_wol_config() in if_rge_hw.c to keep hardware-specific
functions in sync with OpenBSD.
Update rge.4 to document WoL support.

This is part 3 of the support for the new Intel Ethernet E610
family of devices
The ix driver now enables firmware logging on Intel E610 devices
for debugging with Customer Support. Logs are enabled by default
and generated in binary format that requires decoding by support
teams. The collected data is firmware and hardware related for
debugging purposes only.
When the driver loads, it creates a fw_log sysctl node under the
debug section. Events are organized into categories (modules) for
targeted logging, and users can adjust verbosity levels as needed.
This adds sysctl support for the firmware logging feature and
updates the ix(4) manual page with documentation.

This patch changes the default value of the loader tunable
hw.virtio.pci.transitional to 1. This means, virtio uses the
modern mode for transitional devices by default.
The return values of vtpci_modern_probe() and vtpci_legacy_probei()
were chosen to prefer modern mode, but hw.virtio.pci.transitional=0
prevents modern mode.
Setting hw.virtio.pci.transitional to 1 by default seems a better fit.

Wordsmith mentions throughout the manual of syslog and dmesg, to clearly
differentiate them in an externally consisteny way, increasing operator
onboarding speed and elegance.
The daemon that handles general system messages, syslog, describes them
as "system messages", and "messages" is the standard filename. Rewrite
syslog related manual titles to align search results with this, and hier
entries to align the index. Use care to maintain keywords and not add
