The NFSv4 client now uses the highest minor version of NFSv4
by default instead of minor version 0, for NFSv4 mounts.
The "minorversion" mount option may be used to override this default.
This patch updates the man page to reflect this change. While here,
fix nfsstat(8) to be nfsstat(1).

The genet driver (RPi4 Ethernet) had code to pull headers into the
first mbuf if there was only an Ethernet header there. This was
originally needed for ICMPv6 replies, then for forwarded IPv6/TCP.
Now a situation has been found where it is needed for IPv4, when
using NAT with IPFW. Generalize to do this for all protocols.
Rather than using an IPv6-related definition for the length, move
the length to a variable that can be set with sysctl
(hw.genet.tx_hdr_min). Move an old tunable to a new RDTUN variable
with a better name.

Closes#12280
The driver used to configure all available classes with some default
parameters on attach and the rest of t4_sched.c was written with the
assumption that all traffic classes are always valid in the hardware.
But this resulted in a lot of informational messages being logged in the
firmware's circular log, crowding out other more useful messages.
This change leaves the tx scheduler alone during attach to reduce the
spam in the devlog. The state of every class is now tracked separately
from its flags and there is support for an 'uninitialized' state.

Recent firmwares are able to utilize the traffic classes of tx channels
that were previously unused. This effectively doubles the number of
traffic classes available per port for 2 port cards. Stop using the raw
per-channel value in the driver and ask the firmware for the number of
usable traffic classes instead.

After df3b437c1e, older gcc's such as
4.2.1 (still used on earlier branches for e.g. mips and powerpc) and
6.3.0 (still used for some cross-builds) started throwing bogus errors
like:
In file included from /workspace/src/lib/msun/src/s_llround.c:11:0:
/workspace/src/lib/msun/src/s_lround.c:54:31: error: initializer element is not constant

^~~~~~~~
/workspace/src/lib/msun/src/s_lround.c:55:31: error: initializer element is not constant
static const type dtype_max = type_max + 0.5;
^~~~~~~~
Since 'type_min' and 'type_max' are constants declared just above these
lines this error is nonsensical, but older gcc's are not smart enough.
Work around the error by reusing the (type)DTYPE_MIN and (type)DTYPE_MAX
macros, so I can MFC this right away, unbreaking a few stable builds.

In the 2BSD line, the 2.8BSD tapes were the first ones to include a
kernel, both source and a bootable tape. This was an AT&T V7 kernel,
with a number of bug fixes; new features in use at Berkeley; performance
enhancements that were circulating to V7 in the licensee community; and
build system changes. Based on the TUHS archives, it contains none of
the V32 changes, however.
In addition to the source code analysis, Mike Karels relates the story
of how his group lost a customizes to V6 on a PDP-11/40 due to a disk
crash. Since V7 just came out and Bill Jolitz had just brought that up
elsewhere, they replaced their customized V6 with a V7 system, and that
base would eventually become 2.8BSD. (Quarter Century of Unix)
Given both lines of evidence, add a direct line from V7 Unix to 2.8BSD.
Also confirmed that the V6 line to 1BSD and 2BSD was appropriate. 1BSD
and 2BSD included ashell(1) and ex(1). ashell(1) was derived from v6
hell. ex(1) was an enhanced v6 ed. 2.8BSD included process control and
user-land utilities from 4.1BSD

While the correctness of the supported hash algorithms can be tested

When NFSv4.1 support was added to the client, the implementation was
still experimental and, as such, the default minor version was set to 0.
Since the NFSv4.1 client implementation is now believed to be solid
and the NFSv4.1/4.2 protocol is significantly better than NFSv4.0,
I beieve that NFSv4.1/4.2 should be used where possible.
This patch changes the default minor version for NFSv4 to be the highest
minor version supported by the NFSv4 server. If a specific minor version
is desired, the "minorversion" mount option can be used to override
this default. This is compatible with the Linux NFSv4 client behaviour.
This was discussed on freebsd-current@ in mid-May 2021 under
the subject "changing the default NFSv4 minor version" and
the consensus seemed to be support for this change.
It also appeared that changing this for FreeBSD 13.1 was
not considered a POLA violation, so long as UPDATING
and RELNOTES entries were made for it.

Unlike most other properties the 'compatibility' property is stored
in the pool config object and not the DMU_OT_POOL_PROPS object.
This had the advantage that the compatibility information is available
without needing to fully import the pool (it can be read with zdb).
However, this means we need to make sure to update both the copy of
the config in the MOS and the cache file. This wasn't being done.
This commit adds a call to spa_async_request() to ensure the copy of
the config in the cache file gets updated as well as the one stored
in the pool. This same change is made for the 'comment' property
which suffers from the same inconsistency.

This is a more reliable method that accounts for existing pidfiles,

Current method of obtaining the pid for oomprotect="YES"|"ALL" processes
in certain cases fails to find a unique pid.
One such case are rc.d scripts defining command as:
command="daemon"
which results in all processes started via daemon being selected and

$ /etc/rc.d/exampled restart
Stopping exampled.

usage: protect [-i] command
protect [-cdi] -g pgrp | -p pid

protect [-cdi] -g pgrp | -p pid
We have a more reliable way of obtaining pid already defined in rc.subr
and available when protect(1) needs it. We can simply `eval $_pidcmd`
which also invokes `check_process` but properly accounts for existing
pidfile, procname and interpreter settings.
With the change the pidfile is properly obtained.

Update the driver in order not to break its compilation
and make use of the new ENA logging system
Migrate platform code to the new logging system provided by ena_com
layer.
Make ENA_INFO the new default log level.
Remove all explicit use of `device_printf`, all new logs requiring one
of the log macros to be used.
IO queue related attributes are registered statically at driver attach
with the rest of the ENA specific sysctl nodes. However, the number of
queues can be changed at runtime via the `ena_sysctl_io_queues_nb`
request, leading to a potential exposure of attributes for non-existing
queues.
Introduce a new `ena_sysctl_update_queue_node_nb` function, which
updates the sysctl nodes after the number of queues is altered.
This happens by either registering or unregistering node specific oids,
based on a delta between the previous and current queue count.
NOTE: All unregistered oids must be registered again before the driver
detach, e.g. by another call to this function.

If the device supports larger LLQ headers, the user can activate this
feature by setting sysctl tunable 'hw.ena.force_large_llq_header' to '1'

In case the device isn't supporting this feature, the default value (96B)
