- Use the MTU from the first interface as the lagg MTU, all extra interfaces
must be the same.
This fixes using a lagg interface for a vlan or enabling jumbo frames, etc.

the fast or safe/slow method is in use. Fast remains at 1000, slow is
now at 850 (always preferred to TSC). Since the HPET has proven slower
than ACPI-fast on some systems, drop its quality to 900. In the future,
it is hoped that HPET performance will improve as it is the main
timer Intel supports. HPET may move back to 2000 in -current once RELENG_7
is branched to ensure that it gets tested.

containing 64-bit arguments would have explicit padding.
On 64-bit platforms there was no padding, so the dummy
argument was not covering anything. On 32-bit platforms
with weak alignment (i.e. i386) the 64-bit argument did
not need to be aligned, so there too an aditional argument
was introduced. On 32-bit platforms with strong alignment
(i.e. PowerPC) the dummy argument in fact cover the padding.
By elimininating the dummy argument, 64-bit platforms now
have 1 argument less. This also applies to 32-bit platforms
with weak alignment. On PowerPC this doesn't matter, because
the padding is still there. We just don't "name" it.
Deal with those 3 cases.

sys.net.inet.tcp.log_debug = 1
It defaults to enabled for the moment and is to be turned off for
the next release like other diagnostics from development branches.
It is important to note that sysctl sys.net.inet.tcp.log_in_vain
uses the same logging function as log_debug. Enabling of the former
also causes the latter to engage, but not vice versa.
Use consistent terminology in tcp log messages:
"ignored" means a segment contains invalid flags/information and
is dropped without changing state or issuing a reply.
"rejected" means a segments contains invalid flags/information but
is causing a reply (usually RST) and may cause a state change.

SYNCACHE_TIMEOUT to new function syncache_timeout().
o Fix inverted timeout callout engagement logic to actually
enable the timer for the bucket row. Before SYN|ACK was
not retransmitted.
o Simplify SYN|ACK retransmit timeout backoff calculation.
o Improve logging of retransmit and timeout events.
o Reset timeout when duplicate SYN arrives.
o Add comments.
o Rearrange SYN cookie statistics counting.

a proper solution.
- Add a dummy entry point which just calls the C entry points, and try to make
sure it's the first code in the binary.
- Copy a bit more than func_end to try to copy the whole load_kernel()
function. gcc4 puts code behind the func_end symbol.

framework for non-MPSAFE network protocols:
- Remove debug_mpsafenet variable, sysctl, and tunable.
- Remove NET_NEEDS_GIANT() and associate SYSINITSs used by it to force
debug.mpsafenet=0 if non-MPSAFE protocols are compiled into the kernel.
- Remove logic to automatically flag interrupt handlers as non-MPSAFE if
debug.mpsafenet is set for an INTR_TYPE_NET handler.
- Remove logic to automatically flag netisr handlers as non-MPSAFE if
debug.mpsafenet is set.
- Remove references in a few subsystems, including NFS and Cronyx drivers,
which keyed off debug_mpsafenet to determine various aspects of their own
locking behavior.
- Convert NET_LOCK_GIANT(), NET_UNLOCK_GIANT(), and NET_ASSERT_GIANT into
no-op's, as their entire behavior was determined by the value in
debug_mpsafenet.
- Alias NET_CALLOUT_MPSAFE to CALLOUT_MPSAFE.
Many remaining references to NET_.*_GIANT() and NET_CALLOUT_MPSAFE are still
present in subsystems, and will be removed in followup commits.

day of week field correctly, or they remember bad values that are
written into the day of week field. For this reason, ignore the day
of week field when reading the clock on i386 rather than bailing if
it is set incorrectly.
Problems were seen on a number of platforms, including VMWare, qemu,
EPIA ME6000, Epox-3PTA and ABIT-SL30T.
This is a slightly different fix to that proposed by Ted in his PR,
but the same basic idea.

should call uma_zfree() with various spinlock helds. Rearranging the
code would not help here because we cannot break atomicity respect
prcess spinlock, so the only one choice we have is to defer the operation.
In order to do this use a global queue synchronized through the kse_lock
spinlock which is freed at any thread_alloc() / thread_wait() through a
call to thread_reap().
Note that this approach is not ideal as we should want a per-process
list of zombie upcalls, but it follows initial guidelines of KSE authors.

scope security check for the UDPv6 socket credential lookup service,
allowing security policies to bound access to credential information.
While not an immediate issue for Jail, which doesn't allow use of UDPv6,
this may be relevant to other security policies that may wish to control
ident lookups.
While here, eliminate a very unlikely panic case, in which a socket in
the process of being freed is inspected by the sysctl.
