longer do we require SCTP to be in the kernel for the
lib to be able to handle SCTP. We do this by moving
the CRC32c checksum into libkern/crc32.c and then adjusting
all routines to use the common methods. Note that this
will improve the performance of iSCSI since they were
using the old single 256 bit table lookup versus the
slicing 8 algorithm (which gives a 4x speed up in
CRC32c calculation :-D)

Add a note next to fields in network format.
The n_* types are not enough for compiler checks on endianness, and their
use often requires an otherwise unnecessary #include <netinet/in_systm.h>
The typedef in in_systm.h are still there.
the correct behaviour (sorting by distance from the current head position
in the scan direction) and bioq_insert_head() and bioq_insert_tail()
have a well defined (and useful) behaviour, especially when intermixed
with calls to bioq_disksort().
In particular:
- fix a bug in the existing bioq_disksort() that did not use the
current head position correctly;
- redefine semantics of bioq_insert_head() and bioq_insert_tail().
bioq_insert_tail() can now be used as a barrier
between previous and subsequent calls to bioq_disksort().
The code is heavily documented in the source code so please refer
to that for the details.
Much of this code comes from Fabio Checconi. Also thanks to Kirk
for feedback on the (re)definition of bioq_insert_tail().
NOTE: in the current tree there is only a handful of files which
intermix calls to bioq_disksort() with bioq_insert_head() and
bioq_insert_tail(). The ordering of the queue in these situation
was not specified (nor easy to figure out) before, so I doubt any
of that code could be affected by the specification of the API.
Also note that the current implementation is significantly simpler
than the previous one (also used in ata_sort_queue()).
It would be useful to reimplement ata_sort_queue() using
the same code used in bioq_disksort().

a serial number, fall through to the next case so that initial negotiation
still happens. Without this, devices were showing up with only 1 available
tag opening, leading to observations of very poor I/O performance.
This should fix problems reported with VMWare Fusion and ESX. Early
generation MPT-SAS controllers with SATA disks might also be affected.
HP CISS controllers are also likely affected, as are many other
pseudo-scsi disk subsystems.

direct reclaim of the old bss node when any references in packets inflight
are reclaimed (previously the old node would sit in the bss table until
the inactivity processing reclaimed it)

When calling setttyent() after calling endttyent(), pts_valid will never
be set to 1, because the readdir()-loop will likely never vind a pts
that has a higher number than before.
Simplify the code by removing pts_valid. We'll just set maxpts to -1
when we don't have a valid count yet.
Even though I increased the amount of pts(4) entries in /etc/ttys some
time ago, I didn't realize back then those entries shouldn't have been
there in the first place.
I just looked at the getttyent() source code and it turns out when you
call setttyent(), it walks through /dev/pts and looks for the device
with the highest number. After you receive EOF's from getttyent(), it
makes up entries for pts(4) devices.
This means that adding entries for pts(4) is somewhat harmful, because
if you now traverse the list, you get redundant entries, so just remove
them.
It seems ttyslot() calls rindex(), to strip the device name to the last
slash, but this is obviously invalid. /dev/pts/0 should be stripped
until pts/0. Because /etc/ttys only supports TTY names in /dev/, just
strip this piece of the pathname.

it is also need elsewhere like detach so its safe to teardown.
