Since e27961a496, load_rc_config does not
require a service name as its first argument. This change was documented
in the rc.subr script in 0b9c2e7ac5. Let's
update the manual page as well.

The inclusion of 0a0f748641 broke the build with the -DNO_ROOT option.
Specifically, that commit adds some relative paths (with `..`) to METALOG
that make other tools using that log, fail afterwards (tar, makefs...).
It's been argued[1] if this is really something mtree(8) should handle more
graciously. In the meantime, fix the breakage but changing the order in which
the links are created: first in the parent directory, then in the
architecture-specific one.
We keep the architecture-specific directories an the links to the parent
directories. This is something that we might want to change in the future.
This commit is based on a concept patch by avg@.

Information in this document is unchanged between 11.x and 12.x, but
this is intended to be a quick reference for supported architectures.
Also bump .Dd to cover recent changes including MIPS deprecation.

With MIPS' retirement we now have more discontinued architectures than

bsddialog is an attempt to write in permissive license a replacement for
libdialog.
While it is still in early stage it is good enough to already be used in
many areas, it is imported as private lib until it matures enough to be
considered as having a stable ABI
Add in all the variables set in the kenv variable devmatch_blocklist
too. This allows blocking autoloading from the boot loader.

Entries for a few recently defined rc variables
were missing from rc.conf.5. This patch adds
those.
It was not obvious to me what the ordering is,
so I added them to the area where other nfsd
related variables are. I can easily move them.
I also replaced "are" with "is", since it seems to
read better.
This is a content change.

This adds a new ng_device command, NGM_DEVICE_ETHERALIGN, which has no
associated args. After the command arrives, the device begins adjusting all
packets sent out its hook to have ETHER_ALIGN bytes of padding at the
beginning of the packet. The ETHER_ALIGN padding is added only when
running on an architecture that requires strict alignment of IP headers
(based on the __NO_STRICT_ALIGNMENT macro, which is only #define'd on
x86 as of this writing).
This also adds ascii <-> binary command translation to ng_device, both for
the existing NGM_DEVICE_GET_DEVNAME and the new ETHERALIGN command.
This also gives a name to every ng_device node when it is constructed, using
the cdev device name (ngd0, ngd1, etc). This makes it easier to address
command msgs to the device using ngctl(8).

This very questionable feature was enabled in FreeBSD for a very short
time. It was disabled very soon upon merging to RELENG_4 - 23d7f14119.
And in HEAD was also disabled pretty soon - 4bc37f9836.
The tunable has very vague name. Check interface for what? Given that
it was never documented and almost never enabled, I think it is fine
to rename it together with documenting it.
Also, count packets dropped by this tunable as ips_badaddr, otherwise
they fall down to ips_cantforward counter, which is misleading, as
packet was not supposed to be forwarded, it was destined locally.

NOTE: HEADS UP read the note below if your kernel config is not including GENERIC!!
This patch does a bit of cleanup on TCP congestion control modules. There were some rather
interesting surprises that one could get i.e. where you use a socket option to change
from one CC (say cc_cubic) to another CC (say cc_vegas) and you could in theory get
a memory failure and end up on cc_newreno. This is not what one would expect. The
new code fixes this by requiring a cc_data_sz() function so we can malloc with M_WAITOK
and pass in to the init function preallocated memory. The CC init is expected in this
case *not* to fail but if it does and a module does break the
"no fail with memory given" contract we do fall back to the CC that was in place at the time.
This also fixes up a set of common newreno utilities that can be shared amongst other
CC modules instead of the other CC modules reaching into newreno and executing
what they think is a "common and understood" function. Lets put these functions in
cc.c and that way we have a common place that is easily findable by future developers or
bug fixers. This also allows newreno to evolve and grow support for its features i.e. ABE
and HYSTART++ without having to dance through hoops for other CC modules, instead
both newreno and the other modules just call into the common functions if they desire
that behavior or roll there own if that makes more sense.
Note: This commit changes the kernel configuration!! If you are not using GENERIC in
some form you must add a CC module option (one of CC_NEWRENO, CC_VEGAS, CC_CUBIC,
CC_CDG, CC_CHD, CC_DCTCP, CC_HTCP, CC_HD). You can have more than one defined
as well if you desire. Note that if you create a kernel configuration that does not
define a congestion control module and includes INET or INET6 the kernel compile will
break. Also you need to define a default, generic adds 'options CC_DEFAULT=\"newreno\"
but you can specify any string that represents the name of the CC module (same names
that show up in the CC module list under net.inet.tcp.cc). If you fail to add the
options CC_DEFAULT in your kernel configuration the kernel build will also break.

Recent firmwares have more leeway in FEC selection and there is a need
to track the FECs requested by the driver separately from the FEC in use
on the link. The existing dev.<port>.<inst>.fec sysctl can read both but
its behavior depends on the link state and it is sometimes hard to find
out what was requested when the link is up.
Split the fec sysctl into two (requested_fec and link_fec) to get access
to both pieces of information regardless of the link state.

AES-CBC OpenSSL assembly is used underneath.
The glue layer(ossl_aes.c) is based on CHACHA20 implementation.
Contrary to the SHA and CHACHA20, AES OpenSSL assembly logic
does not have a fallback implementation in case CPU doesn't
support required instructions.
Because of that CPU caps are checked during initialization and AES
support is advertised only if available.
The feature is available on all architectures that ossl supports:
i386, amd64, arm64.
The biggest advantage of this patch over existing solutions
(aesni(4) and armv8crypto(4)) is that it supports SHA,
allowing for ETA operations.
