tick driving logic to xl_tick(). Now xl_tick() handles MII tick as
well as periodic updating of statistics.
This change removes a hack used in interrupt handler where it
wanted to update statistics without driving MII tick.
picking the next available one. This may explain why xl(4) sees TX
underrun error with no queued frame. I hope this addresses a long
standing xl(4) watchdog timeout issue as well.

RX descriptor ring. Previously it returned the number of frames
that were successfully passed to upper stack which in turn means it
ignored frames that were discarded due to errors. The number of
processed frames in RX descriptor ring is used to detect whether
driver is out of sync with controller's current descriptor pointer.
Returning number of processed frames reduces unnecessary (probably
wrong) re-synchronization.
While here, remove unnecessary local variable initialization.
handler for 3C90x and 3C90xB/C respectively. This simplifies ioctl
handler as well as enhancing readability.
While I'm here don't reprogram multicast filter when driver is not
running.
This ensures that mbrtowc(3) can be used directly once it has been verified
that there is no CTL* byte. Dealing with a CTLESC byte within a multibyte
character would be complicated.
The new values do occur in iso-8859-* encodings. This decreases efficiency
slightly but should not affect correctness.
Caveat: Updating across this change and rebuilding without cleaning may
yield a subtly broken sh binary. By default, make buildworld will clean and
avoid problems.
Transmission error in tun(4) is queueing error(i.e. ENOBUFS) and it
has nothing to do with collision.

server says it can support. There might be an argument
that this could be one block larger, but since NFS is
a byte granular system, I chose not to do that.

All firmwares can read it, we need to write one anyway for old OF
versions, and if a 512-byte one is present, OS X ignores the 2048-byte one
in favor of it.
This also introduces a new detection path for family 10h and newer

bus_teardown_intr() had been changed to pass the original child device up
in 42734, but the ISA bus was not converted to new-bus until 45720.
or f_ffree fields of "struct statfs" are negative, since the
values that go on the wire are unsigned and will appear to be
very large positive values otherwise. This makes the handling
of a negative f_bavail compatible with the old/regular NFS server.

A string between $' and ' may contain backslash escape sequences similar to
the ones in a C string constant (except that a single-quote must be escaped
and a double-quote need not be). Details are in the sh(1) man page.
This construct is useful to include unprintable characters, tabs and
newlines in strings; while this can be done with a command substitution
containing a printf command, that needs ugly workarounds if the result is to
end with a newline as command substitution removes all trailing newlines.
The construct may also be useful in future to describe unprintable
characters without needing to write those characters themselves in 'set -x',
'export -p' and the like.
The implementation attempts to comply to the proposal for the next issue of
the POSIX specification. Because this construct is not in POSIX.1-2008,
using it in scripts intended to be portable is unwise.
Matching the minimal locale support in the rest of sh, the \u and \U
sequences are currently not useful.

* Cleanup usage of iov's.
* Add support for SCTP_TIMEOUTS socketoption.
* Fix a bug in sctp_recvmsg(): return the msg_flags in case of an error.
* Fix a bug in the error handling of sctp_peeloff(): return the -1.
This fixes heavy interrupt storm and resulting system freeze when using
LAPIC timer in one-shot mode under Xen HVM. There, unlike real hardware,
programming timer with zero period almost immediately causes interrupt.
this there is a rare return path that bogusly appears
to fail when it should not. Also white space correction.
Thanks to Arnaud Lacombe for noticing the problem.
LLVM_HOSTTRIPLE that is defined during the cross-tools stage.
Using clang, you can now build amd64 world and kernel on i386, and vice
versa. Other arches still need work.
