Since OpenSSL 1.1.1, the good old BSD-specific cryptodev engine has been
deprecated in favor of this new engine. However, this engine is not
throughly tested on FreeBSD because it was originally written for Linux.

Also, the author actually meant to enable it by default on BSD platforms but
he failed to do so because there was a bug in the Configure script.

The pwm subsystem consist of API for PWM controllers, pwmbus to register them

It's been reported that pf doesn't handle running out of available ports
for NAT correctly. It freezes until a state expires and it can find a
free port.
Test for this, by setting up a situation where only two ports are
available for NAT and then attempting to create three connections.
If successful the third connection will fail immediately. In an
incorrect case the connection attempt will freeze, also freezing all
interaction with pf through pfctl and trigger timeout.

When we try to find a source port in pf_get_sport() it's possible that
all available source ports will be in use. In that case we call
pf_map_addr() to try to find a new source IP to try from. If there are
no more available source IPs pf_map_addr() will return 1 and we stop
trying.
However, if sticky-address is set we'll always return the same IP
address, even if we've already tried that one.
We need to check the supplied address, because if that's the one we'd
set it means pf_get_sport() has already tried it, and we should error
out rather than keep trying.

If bus_dmamap_load_mbuf() fails following a defrag, the caller of
bwn_dma_tx_start() would free the original mbuf after m_defrag() had
already done so. Fix this by returning the defragged mbuf to the
caller instead. Update bwn_pio_tx_start() similarly for consistency.

r341674 inadvertently introduced a bug where newer mirror components being
tasted would clear the high sc_flags that are not controlled by component
metadata, such as G_MIRROR_DEVICE_FLAG_TASTING. This could plausibly expose
a small window of time during STARTING where device destruction might race
with mirror component addition, probably resulting in a crash.

This fixes the obscure endless loop seen with case-insensitive
patterns containing characters in 128-255 range; originally
found running GNU grep test suite.
Our regex implementation being kludgy translates the characters
in case-insensitive pattern to bracket expression containing both
cases for the character and doesn't correctly handle the case when
original character is in bitmap and the other case is not, falling
into the endless loop going through in p_bracket(), ordinary(),
and bothcases().
Reducing the bitmap to 0-127 range for multibyte locales solves this
as none of these characters have other case mapping outside of bitmap.
We are also safe in the case when the original character outside of
bitmap has other case mapping in the bitmap (there are several of those
in our current ctype maps having unidirectional mapping into bitmap).

check hash to the filesystem inodes. Access attempts to files
associated with an inode with an invalid check hash will fail with
EINVAL (Invalid argument). Access is reestablished after an fsck
is run to find and validate the inodes with invalid check-hashes.
This check avoids a class of filesystem panics related to corrupted
inodes. The hash is done using crc32c.
Note this check-hash is for the inode itself and not any of its
indirect blocks. Check-hash validation may be extended to also
cover indirect block pointers, but that will be a separate (and
more costly) feature.
Check hashes are added only to UFS2 and not to UFS1 as UFS1 is
primarily used in embedded systems with small memories and low-powered
processors which need as light-weight a filesystem as possible.

There was a large refactoring done in CTL to allow multiple ioctl frontend
ports (and respective devices) to be created, particularly for bhyve.
Unfortunately, respective part of bhyve functionality got lost somehow from
the original virtio-scsi commit. This change allows wanted device path to
be specified in either of two ways:
-s 6,virtio-scsi,/dev/cam/ctl1.1
-s 6,virtio-scsi,dev=/dev/cam/ctl2.3
If neither is specified, the default /dev/cam/ctl device is used.
While there, remove per-queue CTL device opening, which makes no sense at
this point.

r336560 was supposed to restore pre-r323954 behaviour when tx_abdicate is

check being made conditional on tx_abdicate being set, it was duplicated
so it occured twice if tx_abdicate was set and once if it was not.
Now when !tx_abdicate, drainage is only checked if the doorbell isn't
pending.

According to the datasheet, the old code checks if port 2 (P2E, 0x4) was
the only enabled port (except port 0, which was ignored by mask 0xfe),
and issue a write to the PCS register to disable all but port 0, right
before ahci_ctlr_reset.
Some other operating systems would issue a port enable to all ports, but
since the current code only does the special initialization for ICH8M,
it entirely and rely on BIOS to do the right thing (the alternative

Slight addition of the code (~200 bytes) is compensated by the saving,
