like a significant slowdown, I've not been able to measure any
signficant difference.

mac_reflect_mbuf_icmp()
mac_reflect_mbuf_tcp()
These entry points permit MAC policies to do "update in place"
changes to the labels on ICMP and TCP mbuf headers when an ICMP or
TCP response is generated to a packet outside of the context of
an existing socket. For example, in respond to a ping or a RST
packet to a SYN on a closed port.

change in mac_lomac: if both flags are set on the new label, we
may not need to always fill out the label (only if one flag is
set, not both). Avoid stomping on a section of the label if we
are in fact modifying both elements.
Because we know that both flags will be set, we don't need to
test whether the range or single are set in later consistency
checks of the range and single -- just test them.
By checking the range of the new vs. the range of the old label
before testing the single against the new range, we implicitly
test that the new single is in the old range. Document this
with a comment.

vendors that list the vendor ID in the proper byte order. The second
section is for vendors that get it backwards. The third is for what
appear to be 'random' ones (although 0xcxxx appears to be coherent
enough that maybe somebody else is assigning those numbers).
Framework labels:
- Re-work the label state assertions to use a set of central
ASSERT_type_LABEL() assertions.
- Test to make sure labels passed to externalize/internalize calls haven't
been destroyed.
- For access control checks, assert the condition of all labels passed in.
- For life cycle events, assert the condition of all labels passed in.
- Add new entry point implementations for new MAC Framework entry points:
mac_test_reflect_mbuf_icmp(), mac_test_reflect_mbuf_tcp(),
mac_test_check_vnode_deleteextattr(), mac_test_check_vnode_listextattr().

UMA_ZFLAG_INTERNAL zones at all. Apparently, Wilko's alpha
was crashing while entering multi-user because, I think, we
were calculating the garbage cachefree for pcpu caches that
essentially don't exist for at least the 'zones' zone and it so
happened that we were reading from an unmapped location.

Improve vertical compactness by using a IGMP_PRINTF() macro rather

often have hundreds of them. This will fix starvation of small dmesg
buffers and allow better debugging to happen. I thought about adding
an override, but there is such a thing as too many knobs. :-)
ntp_update_second twice when we have a large step in case that step
goes across a scheduled leap second. The only way this could happen
would be if we didn't call tc_windup over the end of day on the day of
a leap second, which would only happen if timeouts were delayed for
seconds. While it is an edge case, it is an important one to get
right for my employer.

ultimate trigger for the follow-up fixes in revisions 1.78, 1.80,
1.81 and 1.82 of trap.c. I was simply too pre-occupied with the
gateway page and how it blurs kernel space with user space and
vice versa that I couldn't see that it was all a load of bollocks.
It's not the IP address that matters, it's the privilege level that
counts. We never run in user space with lifted permissions and we
sure can not run in kernel space without it. Sure, the gateway page
is the exception, but not if you look at the privilege level. It's
user space if you run with user permissions and kernel space otherwise.
So, we're back to looking at the privilege level like it should be.
There's no other way.

- Fix up TX speed changes.
- Make mpi-350 cards sort-of work with new firmware. It RXs okay but TXs
only work for about 14 packets then fails to get an interrupt. The
TX watchdog fires. It has been reported that my hack for now doesn't
break cards with the older firmware. It appears my card has lost
the ability to RX or TX at all but other peoples cards work. I assume
it got damaged in tansport.

count handling of station entries in hostap mode:
Input path:
o driver is now expected to find the node associated with the
sender of a received frame; use ic_bss if none is located
o driver passes the (referenced) node into ieee80211_input for
use within the wlan module and is responsible for cleaning up
on return
o the antenna state is no longer passed up with each frame; this
is now considered driver-private state and drivers are responsible
for keeping it in the driver-private part of a node
Output path:
Revamp output path for management frames to eliminate redundant
locking that causes problems and to correct reference counting
bogosity that occurs when stations are timed out due to inactivity
(in AP mode). On output the refcnt'd node is stashed in the pkthdr's
recvif field (yech) and retrieved by the driver. This eliminates
an unref/ref scenario and related node table unlock/lock due to the
driver looking up the node. This is particularly important when
stations are timed out as this causes a lock order reversal that
can result in a deadlock. As a byproduct we also reduce the overhead
for sending management frames (minimal). Additional fallout from
this is a change to ieee80211_encap to return a refcn't node for
tieing to the outbound frame. Node refcnts are not reclaimed until
after a frame is completely processed (e.g. in the tx interrupt
handler). This is especially important for timed out stations as
this deref will be the final one causing the node entry to be
reclaimed.
Additional semi-related changes:
o replace m_copym use with m_copypacket (optimization)
o add assert to verify ic_bss is never free'd during normal operation
o add comments explaining calling conventions by drivers for frames
going in each direction
o remove extraneous code that "cannot be executed" (e.g. because
pointers may never be null)
that caused a 3-4 times slow down in performance.
(the primary Sparc64 developers are all using OFW_NEWPCI already, so it is
the best code path for users)
quietly discard them; this just permits them to be collected with bpf)
o add a counter for the number of rate control frames discarded when not in
monitor mode
o move the rx "too short" statistic in the stat structure so non-error rx stats
are together (NB: ABI change to apps that collect stats via driver ioctl)
mistakes (this mistake was not an issue because the length is only used to
decide whether or not to allocate a cluster)
o while here, move a beacon length comment to the "right place"
_pmap_allocpte(): Guarantee that the page table page is zero filled before
