thinking it had the whole chunk. This could cause a crash if
a large packet drop came in. Fixed by adjusting the trunc length
down to the limit.
- Large sacks with lots of segments could also have same issue. Changed
duplicate and segment handling to use proper get_m_ptr function to
pull each block from mbuf chains.
ioctl routines if we are running with !mpsafenet
- Change un-conditional Giant acquisition around ifpromisc
to occur only if we are running with !mpsafenet
With these locking bits in place, we can now remove the Giant
requirement from BPF, so drop the D_NEEDGIANT device flag.
This change removes Giant acquisitions around BPF device
handlers (read, write, ioctl etc).

or idle priority of another process owned by the same user. This means
that privilege in rtprio(2) (and rtprio_thread(2)) is required indirectly
via p_cansched(9) or directly to set realtime/idle privilege, rather than
directly affecting target process authorization.
- Fix so VRF's will clean themselves up when no references are around.
- Allow sctp_ifa to be passed into inpcb_bind, addr_mgmt_ep_sa to bypass
normal validation checks.
- turn auto-asconf off for subset bound sockets
- Moves all logging to use KTR. This gets rid of most
of the logging #ifdef's with a few exceptions reducing
the number of config options for SCTP.

Also, remove usb_malloc_type: it was unused.
Remove METHODS_NONE: it was unused.
Move include of opt_usb.h from usb_port.h to usb.h, since usb_port.h is
going away (there will be a usb_compat.h for out-of-tree drivers that want it).
- Depessimize userret() in kernels where KTRACE is enabled by doing an
unlocked check of the per-process queue of pending events before
acquiring any locks. Previously ktr_userret() unconditionally acquired
the global ktrace_sx lock on every return to userland for every thread,
even if ktrace wasn't enabled for the thread.
- Optimize the locking in exit() to first perform an unlocked read of
p_traceflag to see if ktrace is enabled and only acquire locks and
teardown ktrace if the test succeeds. Also, explicitly disable tracing
before draining any pending events so the pending events actually get
written out. The unlocked read is safe because proc lock is acquired
earlier after single-threading so p_traceflag can't change between then
and this check (well, it can currently due to a bug in ktrace I will fix
next, but that race existed prior to this change as well).

during execve() when turning off tracing due to executing a setuid binary
as non-root. Previously this could fail to acquire Giant and fail an
assertion if the ktrace file was on a non-MPSAFE filesystem and the
executable was on an MPSAFE filesystem.

bridged, previously legitimate traffic was not passed as the bridge could not
tell that it was on a different Ethernet segment.
All non-tagged traffic is treated as vlan1 as per IEEE 802.1Q-2003
than the 5288.
It is not correctly implemented in earlier silicon, and the BIOS often
lies about AHCI capability on platforms where these chips are deployed.
With this change I am able to boot FreeBSD on the ASUS Vintage AH-1

timing loops being optimized away.
Once apon a time, gcc promised not to optimize away timing loops, but
gcc started optimizing away the call to a null function in the timing
loop here some time between gcc-3.3.3 and gcc-3.4.6, and it started
optimizing away the timing loop itself some time between gcc-3.4.6
and gcc-4.2.
