new NFS client. It will then be reduced to whatever the
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
pre-bulldozer cpus, pre-10h hardware should not be affected.

versions instead. They were never needed as bus_generic_intr() and
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.
Quoting the ath9k commit message:
At present the noise floor calibration is processed in supported
control and extension chains rather than required chains.
Unnccesarily doing nfcal in all supported chains leads to
invalid nf readings on extn chains and these invalid values
got updated into history buffer. While loading those values
from history buffer is moving the chip to deaf state.
This issue was observed in AR9002/AR9003 chips while doing
associate/dissociate in HT40 mode and interface up/down
in iterative manner. After some iterations, the chip was moved
to deaf state. Somehow the pci devices are recovered by poll work
after chip reset. Raading the nf values in all supported extension chains
when the hw is not yet configured in HT40 mode results invalid values.

The checks should function as follows:
* AR_SREV_<silicon> : check macVersion matches that version id
* AR_SREV_<silicon>_<revision> : check macVersion and macRevision match
the version / revision respectively
* AR_SREV_<silicon>_<revision>_OR_LATER: check that
+ if the chip silicon version == macVersion, enforce revision >= macRevision
+ if the chip silicon version > macVersion, allow it.
For example, AR_SREV_MERLIN() only matches AR9280 (any revision),
AR_SREV_MERLIN_10() would only match AR9280 version 1.0, but
AR_SREV_MERLIN_20_OR_LATER() matches AR9280 version >= 2.0 _AND_
any subsequent MAC (So AR9285, AR9287, etc.)
The specific fixes which may impact users:
* if there is Merlin hardware > revision 2.0, it'll now be correctly
matched by AR_SREV_MERLIN_20_OR_LATER() - the older code simply
would match on either Merlin 2.0 or a subsequent MAC (AR9285, AR9287, etc.)
* Kite version 1.1/1.2 should now correctly match. As these macros
are used in the AR9285 reset/attach path, and it's assumed that the
hardware is kite anyway, the behaviour shouldn't change. It'll only
change if these macros are used in other codepaths shared with
older silicon.

Reference code that shows how to get a packet's timestamp out of
cxgbe(4). Disabled by default because we don't have a standard way
today to pass this information up the stack.
The timestamp is 60 bits wide and each increment represents 1 tick of
the T4's core clock. As an example, the timestamp granularity is ~4.4ns
for this card:
# sysctl dev.t4nex.0.core_clock

- Enable 5-tuple and every-packet lookup.
- Setup the default filter mode to allow filtering/steering based on IP
protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match
type; all combined together. You can also filter based on MAC index,
Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll
have to modify the default filter mode and exclude some of the
match-fields in it.
IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter
rules.
- Add driver ioctls to get/set the global filter mode.
- Add driver ioctls to program and delete hardware filters. A couple of
the "switch" actions that rewrite Ethernet and VLAN information and
switch the packet out of another port may not work as the L2 code is not
yet in place. Everything else, including all "drop" and "pass" rules
with RSS or absolute qid, should work.
