MFC: r268008
There might be a potential race condition for the NFSv4 client
when a newly created file has another open done on it that
update the open mode. This patch moves the code that updates
the open mode up into the block where the mutex is held to
ensure this cannot happen. No bug caused by this potential
race has been observed, but this fix is a safety belt to ensure
it cannot happen.
Posix strptime() requires support for %t and %n, which were added
to the illumos port. Curiously we were skipping white spaces by
default in most other cases making %t meaningless.
We now skip spaces in the case of the %e specifier as strftime(3)
explicitly adds a space for the single digit case.

The TCP delayed ACK logic isn't aware of LRO passing up large aggregated
segments thinking it received only one segment. This causes it to enable
the delay the ACK for 100ms to wait for another segment which may never
come because all the data was received already.
Doing delayed ACK for LRO segments is bogus for two reasons: a) it pushes
us further away from acking every other packet; b) it introduces additional
delay in responding to the sender. The latter is especially bad because it
is in the nature of LRO to aggregated all segments of a burst with no more
coming until an ACK is sent back.
Change the delayed ACK logic to detect LRO segments by being larger than
the MSS for this connection and issuing an immediate ACK for them to keep
the ACK clock ticking without interruption.

- Improve performance by fixing incorrect Rx/Tx handling
- Rename definition of AXGE_* to reflect reality
- Add new USB IDs
- Add proper rangechecks in "axge_rx_frame()" function and
fix receive loop header parsing.
- Disable hardware checksumming until it is properly tested.
Initialize r_flags the same way in all cases using a sanitized copy of
flags that has several bits cleared. The RF_WANTED and RF_FIRSTSHARE
bits are invalid in this context, and we want to defer setting RF_ACTIVE
in r_flags until later. This should make rman_get_flags() return
the correct answer in all cases.
Add a KASSERT() to catch callers which incorrectly pass the RF_WANTED
or RF_FIRSTSHARE flags.
Do a strict equality check on the share type bits of flags. In
particular, do an equality check on RF_PREFETCHABLE. The previous
code would allow one type of mismatch of RF_PREFETCHABLE but disallow
the other type of mismatch. Also, ignore the the RF_ALIGNMENT_MASK
bits since alignment validity should be handled by the amask check.
This field contains an integer value, but previous code did a strange
bitwise comparison on it.
Leave the original value of flags unmolested as a minor debug aid.
Change the start+amask overflow check to a KASSERT() since it is just
meant to catch a highly unlikely programming error in the caller.

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that
instruction)
PR20071 identifies a problem in PowerPC's fast-isel implementation
for floating-point conversion to integer. The fctiduz instruction
was added in Power ISA 2.06 (i.e., Power7 and later). However, this
instruction is being generated regardless of which 64-bit PowerPC
target is selected.
The intent is for fast-isel to punt to DAG selection when this
instruction is not available. This patch implements that change.
For testing purposes, the existing fast-isel-conversion.ll test adds
a RUN line for -mcpu=970 and tests for the expected code generation.
Additionally, the existing test fast-isel-conversion-p5.ll was found
to be incorrectly expecting the unavailable instruction to be
generated. I've removed these test variants since we have adequate
coverage in fast-isel-conversion.ll.
This is needed to compile clang with debug+asserts on older powerpc64
and ppc970 targets.
