Now that CloudABI's sockets API has been changed to be addressless and
only connected socket instances are used (e.g., socket pairs), they have
become fairly similar to pipes. The only differences on CloudABI is that
socket pairs additionally support shutdown(), send() and recv().
To simplify the ABI, we've therefore decided to remove pipes as a
separate file descriptor type and just let pipe() return a socket pair
of type SOCK_STREAM. S_ISFIFO() and S_ISSOCK() are now defined
identically.
This helps to detect when UDP hash types can be supported.

FreeBSD loader expects to have mmsz variable set by bootloader.
U-Boot behaviour is that if buffer size is not big enough to keep
whole memory map, assign the smallest correct buffer size to sz
and return error.
In other words U-Boot assumes that nobody will need mmsz value when buffer
is not filled with memory map, which is not true, so calculated pages value
was too big to allocate.
Solution: Simply assign default value to mmsz.

Two modules with the same name cannot be loaded, so Marvell specific drivers
cannot have the same name as generic drivers.
Files with the same name, even in different folder overlaps their .o files.
Change armada38x/rtc.c to armada38x/armada38x_rtc.c fix it.

It will be needed by hn(4) to configure its RSS key and hash
type/function in the transparent VF mode in order to match VF's
RSS settings. The description of the transparent VF mode and
the RSS hash value issue are here:
https://svnweb.freebsd.org/base?view=revision&revision=322299https://svnweb.freebsd.org/base?view=revision&revision=322485
These are generic enough to promise two independent IOCs instead
of abusing SIOCGDRVSPEC.
Setting RSS key and hash type/function is a different story,
which probably requires more discussion.
Comment about UDP_{IPV4,IPV6,IPV6_EX} were only in the patch
in the review request; these hash types are standardized now.

superblocks created in revision 322297 only works on disks
with sector sizes up to 4K. This update allows the recovery
information to be created by newfs and used by fsck on disks
with sector sizes up to 64K. Note that FFS currently limits
filesystem to be mounted from disks with up to 8K sectors.
Expanding this limitation will be the subject of another

There is no big need to burn CPU if other side may be not there yet. For
example, the PLX hardware by default enables the NTB link up on reset, not
dependig on driver to do it. In case of Intel hardware this also reduces
race between MSI-X workaround negotiation and upper layers, using the same
scratchpad registers in different time.

In the case where write(2) does not return -1, it does not initialize errno.
This can happen when a broken pipe causes a short write.
I attempted to adapt the submitted test case to ATF but could not figure out
how to make the test run in the ATF environment. So the aborted test is
left disabled, in case someone would like to run it manually or fix it.

It's possible this will be moved later, however as it's currently only used
by the MP code put it there.
So far the only instance of a quirk is when the list of CPUs may be
incorrect. This can happen on virtual machines with a hard coded
devicetree, but where the user may then set the number of CPUs as an
argument. This is the case on the ARM models so include the model specific
compat strings for these, including the spelling mistake found in some of
the OpenplatformPkg dtb files.
