Unconditionally call the setsockopt for IPV6_V6ONLY for v6 linux sockets
no matter whether we are compiled as module or if our default of the
net.inet6.ip6.v6only sysctl already matches what we would set.
This avoids unnecessary complications with modules, VIMAGES, INET6 and
the sysctl value, especially considering that most users will use
linux compat as a module.

T3 firmware 7.8.0 for cxgb(4)
Make sure that the primary native brandinfo always gets added
first and the native ia32 compat as middle (before other things).
o(ld)brandinfo as well as third party like linux, kfreebsd, etc.
stays on SI_ORDER_ANY coming last.
The reason for this is only to make sure that even in case we would
overflow the MAX_BRANDS sized array, the native FreeBSD brandinfo
would still be there and the system would be operational.

lindev(4) [1] is supposed to be a collection of linux-specific pseudo
devices that we also support, just not by default (thus only LINT or
module builds by default).
While currently there is only "/dev/full" [2], we are planning to see more
in the future. We may decide to change the module/dependency logic in the
future should the list grow too long.
This is not part of linux.ko as also non-linux binaries like kFreeBSD
userland or ports can make use of this as well.

Add more statistics variables for IPcomp.
Try to version the struct in a backward compatible way.
People asked for the versioning of the stats structs in general before.
Note: old netstat binaries, as only consumer, continue to work as they are
still using kvm but will not display the new stats. [1]

In case the compression result is the same size as the orignal version,
the compression was useless as well. Make sure to not update the data
and return, else we would waste resources when decompressing.
This also avoids the copyback() changing data other consumers like
xform_ipcomp.c would have ignored because of no win and sent out without
noting that compression was used, resulting in invalid packets at the
receiver.
Only add the IPcomp header if crypto reported success and we have a lower
payload size. Before we had always added the header, no matter if we
actually send out compressed data or not.
With this, after the opencrypto/deflate changes, IPcomp starts to work
apart from edge cases. Leave it disabled by default until those are
fixed as well.

Change memory managment from a fixed size array to a list.
This is needed to avoid running into out of buffer situations
where we cannot alloc a new buffer because we hit the array size
limit (ZBUF).
Use a combined allocation for the struct and the actual data buffer
to not increase the number of malloc calls. [1]
Defer initialization of zbuf until we actually need it.
Make sure the output buffer will be large enough in all cases.

Z_PARTIAL_FLUSH is marked deprecated. Z_SYNC_FLUSH is the suggested
replacement but only use it for inflate. For deflate use Z_FINISH
as Z_SYNC_FLUSH adds a trailing marker in some cases that inflate(),
despite the comment in zlib, does npt seem to cope well with, resulting
in errors when uncompressing exactly fills the outbut buffer without
a Z_STREAM_END and a successive call returns an error.

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 several device freeze counting bugs.
- Remove code that years ago was closing race between request submission
to SIM and device/SIM freeze. That race become impossible after moving from
spl to mutex locking, while this workaround causes some unexpected effects.
- fix a LOR between process lock and pmc thread mutex
- fix a system deadlock on process exit when the sample buffer
is full (pmclog_loop blocked in fo_write) and pmcstat exit.
It seems generation of link state change of e1000phy(4) is not
reliable on some Marvell PHYs. If msk(4) know it still does not
have established link check whether msk(4) missed the link state
change by looking into polled link state.

r198996:
Remove unnecessary header file.
r198997:
It's normal to see Rx FIFO overruns under high network load and
showing the message creates other side-effects. Remove the Rx
FIFO overrun message in interrupt handler. msk(4) should recover
from the FIFO overruns without any user intervention. Users can
still check the Rx FIFO overrun counter from MAC MIB statistics
maintained in driver(dev.msk.0.stats.rx.overflows).
Add a check to know whether driver is still running after
reacquiring driver lock in Rx handler. re(4) drops a driver lock
before passing received frame to upper stack and reacquire the
lock. During the time window ioctl calls could be executed and if
the ioctl was interface down request, driver will stop the
controller and free allocated mbufs. After that when driver comes
back to Rx handler again it does not know what was happend so it
could access free mbufs which in turn cause panic.

For AR8132 fast ethernet controller, do not report 1000baseT
capability to mii(4). Even though AR8132 uses the same model/
revision number of F1 gigabit PHY, the PHY has no ability to
establish 1000baseT link. I have no idea why Atheros use the same
device/model id for this PHY.
With this change atphy(4) does not report 1000baseT media
capability and manual 1000baseT configuration is also disabled
which is more desirable behavior for 10/100Mbps PHY.

Add hack to pass controller specific information to phy driver.
Unlike most other PHYs there is no easy way to know which media
