These parameters may be changed via ifconfig(8); by default,
mgt / mcast rates are lowest possible and ucast rate is not set
(matches previous configuration).
While here, store some variables locally for better readability.
The vfs.mountroot.timeout tunable and .timeout directive in a mount.conf(5)
file allow specifying a wait timeout for the device(s) hosting the root
filesystem to become usable. The current mechanism for waiting for devices
and detecting their availability can't be used for zfs-hosted filesystems.
See the comment #20 in the PR for some expanded detail on these points.
This change adds retry logic to the actual root filesystem mount. That is,
insted of relying on device availability using device name lookups, it uses
the kernel_mount() call itself to detect whether the filesystem can be
mounted, and loops until it succeeds or the configured timeout is exceeded.
These changes are based on the patch attached to the PR, but it's rewritten
enough that all mistakes belong to me.

Upstream DTBs don't provide IRQ lines for the RNG. Moreover, harvesting
bytes as often as the RNG interrupt is triggered (87 times per sec) is an
overkill.
For these reasons, get rid of the interrupt mode and make callout mode the
default, with random bits harvested every 4 seconds.

If tftpd receives a command with an unknown opcode, it simply exits 1. It
doesn't send an ERROR packet, and the client will hang waiting for one. Fix
it.
PR: 226005
MFC after: 3 weeks
On a WRQ (write request) tftpd checks whether the client has access
permission for the file in question. If not, then the write is prevented.
However, tftpd doesn't reply with an ERROR packet, nor does it abort.
Instead, it tries to receive the packet anyway.
The symptom is slightly different depending on the nature of the error. If
the target file is nonexistent and tftpd lacks permission to create it, then
tftpd will willingly receive the file, but not write it anywhere. If the
file exists but is not writable, then tftpd will fail to ACK to WRQ.

tftpd(8) says that files may only be written if they already exist and are
publicly writable. tftpd.c verifies that a file is publicly writable if it
uses an absolute pathname. However, if the pathname is relative, that check
is skipped. Fix it.
Note that this is not a security vulnerability, because the transfer
ultimately doesn't work unless the file already exists and is owned by user
nobody. Also, this bug does not affect the default configuration, because
the default uses the "-s" option which makes all pathnames absolute.

Apply patch submitted with PR 217159 to make ps use unlimited
width when not associated with a terminal (i.e., none of stdout, stdin,

This change was requested to work around lack of -ww in scripts from
third-party packages, including Hadoop, and adds a small measure of
Linux compatibility. Hopefully few if any non-interactive scripts
depend on the old default of 79.

Most sysctl nodes only return a single value, but some nodes return an
array of values (e.g. kern.cp_time). sysctl(8) understand how to display
the values of a node that returns multiple values (it prints out each
numeric value separated by spaces). However, until now sysctl(8) has
only been able to set sysctl nodes to a single value. This change
allows sysctl to accept a new value for a numeric sysctl node that contains
multiple values separated by either spaces or commas. sysctl(8) parses
this list into an array of values and passes the array as the "new" value
to sysctl(2).

On an RRQ, tftpd doesn't exit as soon as it's finished receiving a file.
Instead, it waits five seconds just in case the client didn't receive the
server's last ACK and decides to resend the final DATA packet.
Unfortunately, this created a 5 second delay from when the client thinks
it's done sending the file, and when the file is available for other
processes.
Fix this bug by closing the file as soon as receipt is finished.

With autodetection turned on, hitting the filesystem everytime we need to
calculate choices for the kernel carousel is kind of slow. Cache once on the
first listing and reload it anytime the config is reloaded in case any of
the loader.conf(5) changes that affect this (kernel, kernels,
kernels_autodetect) have changed. This also picks up the case where we've
changed currdev and the autodetected kernels could change.
Usually this is just ignored:
