Detect when we are polling from kernel via cngetc() in the boot process and
reserve the keypresses so they do not get passed to syscons.

Add run(4), a driver for Ralink RT2700U/RT2800U/RT3000U USB 802.11agn devices.
This driver was written for OpenBSD by Damien Bergamini and ported over by
Akinori Furukoshi.
When the regular NFS server replied to a UDP client out of the replay
cache, it did not free the request argument mbuf list, resulting in a leak.
This patch fixes that leak.
PR: kern/144330
When receiving a management frame, pass the mbuf to bpf before calling
iv_recv_mgmt(). iv_recv_mgmt() will generate management frame
responses
and pass them to bpf before the management frame that triggered the
response.

From tzdata2010g:
- Bangladesh cancels DST.
- Palestine goes into DST one day later than expected.
- Russian timezones update:
Europe/Samara goes to Moscow time.
Asia/Kamchatka goes to Moscow+8 time.
Asia/Anadyr goes to Moscow+8 time.

Accessing an mbuf after it has been handed off to the hardware is a bad
race as it could already have been tx'd and freed by that time. Place
the bpf tap just _before_ writing the gen bit.
This fixes a panic when running tcpdump on a cxgb interface.
r204274:
There is no need to test __FreeBSD_version for features that have
been around for a long time now (7.1-ish or even earlier); assume
they are present. These includes MSI, TSO, LRO, VLAN, INTR_FILTERS,
FIRMWARE, etc.
Also, eliminate some dead code and clean up in other places as part
of this quick once-over.
r204348:
Support IFCAP_VLANHWTSO in cxgb(4). It works with or without vlanhwtag.
While here, remove old DPRINTFs and tidy up the capability code a bit.
r204921:
Better TwinAx transceiver detection.

r205944:
Refresh the firmware version immediately after it is upgraded (or downgraded).
r205945:
Improved PHY EDC settings.
r205946:
Do not attempt to retrieve interrupt information before it is available.
r205947:
Fix build with "nooptions INET"
r205948:
Fix tx drop statistics.
r205949:
Fix signed/unsigned mix-up that allowed txq->in_use to grow beyond txq->size.
r205950:
Multiple fixes related to queue set sizing and resources:
- Only the tunnelq (TXQ_ETH) requires a buf_ring, an ifq, and the watchdog/timer
callouts. Do not allocate these for the other tx queues.
- Use 16k jumbo clusters only on offload capable cards by default.
- Do not allocate a full tx ring for the offload queue if the card is not
offload capable.
- Slightly better freelist size calculation.
- Fix nmbjumbo4 typo, remove unneeded global variables.
r206109:
Increase response queue size to avoid starvation, add a counter
to track it when it does occur.
Clean up some printing stuff so that we can have a bit finer control
on debug output. Add a new platform function requirement to allow
for printing based upon the ITL nexus instead of the isp unit plus
channel, target and lun. This allows some printouts and error messages
from the core code to appear in the same format as the platform's
subsystem (in FreeBSD's case, CAM path).
Revision 205075 and 205104:
---------205075----------
With the recent change of the sctp checksum to support offload,
no delayed checksum was added to the ip6 output code. This
causes cards that do not support SCTP checksum offload to
have SCTP packets that are IPv6 NOT have the sctp checksum
performed. Thus you could not communicate with a peer. This
adds the missing bits to make the checksum happen for these cards.
-------------------------
---------205104----------
The proper fix for the delayed SCTP checksum is to
have the delayed function take an argument as to the offset
to the SCTP header. This allows it to work for V4 and V6.
This of course means changing all callers of the function
to either pass the header len, if they have it, or create
it (ip_hl << 2 or sizeof(ip6_hdr)).

-------------------------
sched_getparam was just plain broke for time-share
processes. It did not return an error but instead
just let garbage be passed back. This I fix so
it actually properly translates the priority the
process is at to a posix's high means more priority.
I also fix it so that if the ULE scheduler has bumped
it up to a realtime process you get back a sane value
i.e. the highest priority (63 for time-share).
sched_setscheduler() had the setting of the
timeshare class priority disabled. With some notes
about rejecting the posix high numbers is greater
priority and use nice instead. This fix also
adjusts that to work, with the cavet that a t-s
process may well get bumped up or down i.e. the
setscheduler() will NOT change the nice value only
the current priority. I think this is reasonable
considering if the user wants to play with nice then
he can. At least all the posix'ish interfaces now
respond sanely.

o Add support for UltraSparc-IV+:
- Swap the configuration of the first and second large dTLB as with
US-IV+ these can only hold entries of certain page sizes each, which
we happened to chose the non-working way around.
- Additionally ensure that the large iTLB is set up to hold 8k pages
(currently this happens to be a NOP though).
- Add a workaround for US-IV+ erratum #2.
- Turn off dTLB parity error reporting as otherwise we get seemingly
false positives when copying in the user window by simulating a
fill trap on return to usermode. Given that these parity errors can
be avoided by disabling multi issue mode and the problem could be
reproduced with a second machine this appears to be a silicon bug of
some sort.
- Add a membar #Sync also before the stores to ASI_DCACHE_TAG. While
at it, turn of interrupts across the whole cheetah_cache_flush() for
simplicity instead of around every flush. This should have next to no
impact as for cheetah-class machines we typically only need to flush
the caches a few times during boot when recovering from peeking/poking
non-existent PCI devices, if at all.
- Just use KERNBASE for FLUSH as we also do elsewhere as the US-IV+
documentation doesn't seem to mention that these CPUs also ignore the
address like previous cheetah-class CPUs do. Again the code changing
LSU_IC is executed seldom enough that the negligible optimization of
using %g0 instead should have no real impact.
With these changes FreeBSD runs stable on V890 equipped with US-IV+
and -j128 buildworlds in a loop for days are no problem. Unfortunately,
the performance isn't were it should be as a buildworld on a 4x1.5GHz
US-IV+ V890 takes nearly 3h while on a V440 with (theoretically) less
powerfull 4x1.5GHz US-IIIi it takes just over 1h. It's unclear whether
this is related to the supposed silicon bug mentioned above or due to
another issue. The documentation (which contains a sever bug in the
description of the bits added to the context registers though) at least
doesn't mention any requirements for changes in the CPU handling besides
those implemented and the cache as well as the TLB configurations and
handling look fine.
o Re-arrange cheetah_init() so it's easier to add support for SPARC64
V up to VIIIfx CPUs, which only require parts of this initialization.

If there is multiple PMCs for the same interrupt ignore new post.
This will indirectly fix a bug where the thread will be pinned
forever if the assert is not compiled.
