Since the existing implementation searches ':' backward, a path which
includes ':' could not be mounted. You can now mount such path by
enclosing an IP address by '[]'.
Though we should change to search ':' forward, it will break
'ipv6addr:path' which is currently working. So, it still searches ':'
backward, at least for now.
These fixes correct a problem in the file system that treats large
inode numbers as negative rather than unsigned. For a default
(16K block) file system, this bug began to show up at a file system
size above about 16Tb.
These fixes also update newfs to ensure that it will never create a
filesystem with more than 2^32 inodes.
They also update libufs, tunefs, and growfs so that they properly
handle inode numbers as unsigned.

- Give ATA/SATA SIMs info about ATAPI packet size, supported by device.
- Make ATA XPT to reject longer SCSI CDBs then supported by device, or
any SCSI CDBs, if device doesn't support ATAPI.
Implement the "-i" option to sysctl(8), to ignore failures while
retrieving individual OIDs. This allows the same list of OIDs to be
passed to sysctl(8) across different systems where particular OIDs may
not exist, and still get as much information as possible from them.

This corrects a bug that manifested itself as identifying the last
cylinder group of a UFS1 filesystem as bad. The error was in the check
and not in the cylinder group itself. So even though fsck fixed the
cylinder group correctly, it was still endlessly reported as bad.
This bug first appeared in 8.0 so does not apply to earlier releases.

- Add -v argument to `camcontrol identify` command. It makes camcontrol
print full identify data block.
- Improve identify result view a bit and add TRIM support.
Remove dead code. This section of code is only run in the
(sblock.fs_magic == FS_UFS1_MAGIC) case, so the check within the
loop is redundant.

(S)LIST_HEAD_INITIALIZER takes a (S)LIST_HEAD as an argument.
Fix some wrong usages.
Note: this does not affect generated binaries as this argument is not used.

ifconfig(8) is documented to take a ISO 3166-1 country code to set the
regulatory domain with the "country" parameter, but will also take a full
country name. The man page warns that only the ISO code is unambiguous.
In reality, however, the first match on either would be accepted, leading
to "DE" being interpreted as the "DEBUG" country rather than Germany, and
"MO" selecting Morocco rather than the correct country, Macau.
Fix this by always checking for an ISO CC match first, and only search on
the full country name if that fails.

Increase default block size from 4K to 64K. It was reduces 6 yeard ago,
when trees were big and FAST mode was enabled by default.
So small block size doesn't benefits linear I/O operations in FAST and
significantly slowdowns in ECONOMIC (default) mode. For single stream random
I/Os so small block doesn't give much benefits, as access time is usually
bigger then transfer time there. Same time it requires all heads to seek
together for every single request, reducing performance on parallel load.
Introduce ATA_CAM kernel option, turning ata(4) controller drivers into
cam(4) interface modules. When enabled, this option deprecates all ata(4)
peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers
(ada, cd, ...) and interfaces to be natively used instead.
As side effect of this, ata(4) mode setting code was completely rewritten
to make controller API more strict and permit above change. While doing
this, SATA revision was separated from PATA mode. It allows DMA-incapable
SATA devices to operate and makes hw.ata.(ata|atapi)_dma tunable work again.
Also allow ata(4) controller drivers (except some specific or broken ones)
to handle larger data transfers. Previous constraint of 64K was artificial
and is not really required by PCI ATA BM specification or hardware.

Change gmirror default balance algorithm from "split" to improved "load".
"split" is very ineffective for devices with rotating media as HDDs.
To be effective, it needs that transfer time reduction due to block
splitting was bigger then access time increase due to non-sequential
access. For modern HDDs I was able to reproduce it only with read sizes
of 2MB and above, which is almost not applicable in real life.
"load" algorithm same time is more universal and effective now.
Drop USB mass storage devices support from ata(4). It is out of the build as
long as I remember, and completely superseded by better maintained umass(4).
It's main idea was to optionally avoid CAM dependency for such devices, but
with move ATA to CAM, it is not actual any more.

- Extend XPT-SIM transfer settings control API. Now it allows to report to
SATA SIM number of tags supported by each device, implement ATA mode and
SATA revision negotiation for both SATA and PATA SIMs.
- Make ahci(4) and siis(4) to use submitted maximum tag number, when
scheduling requests. It allows to support NCQ on devices with lower tags
count then controller supports.
- Make PMP driver to report attached devices connection speeds.
- Implement ATA mode negotiation between user settings, device and
controller capabilities.
- Improve ATA mode/SATA revision control.
Fix parsing of mount options specified with -o in case an option with
value is preceded by an option without value (for example -o
option1,option2=value). Options must be separated before searching for
'='. Also compare pnextopt explicitly against NULL.

Ensure 'kvm' is always initialized. If "-M" was not specified and the
garbage value on the stack was not zero, then 'ddb capture' would try to
use the garbage value as a kvm_t pointer.
Make dhclient use bootpc (68) as the source port for unicast
DHCPREQUEST packets instead of allowing the protocol stack to pick
a random source port.
This fixes the behaviour where dhclient would never transition
from RENEWING to BOUND without going through REBINDING in networks
which are paranoid about DHCP spoofing, such as most mainstream
cable-broadband ISP networks.

Change the default transport protocol for use by the Mount protocol
and the NFS Null RPC done by mount_nfs from UDP to TCP, so that it is
consistent with the kernel, which already uses NFS over TCP by
default. Without this change, doing an NFS mount
against a server that only supports UDP results in an unusable
mount point if a transport protocol option wasn't specified for the
mount.
