read wasn't flagging the SYNC mode was enabled. The temp

This didn't show up in testing because a random number
of 1030 cards set a bit that says "honor BIOS negotiation",
which means this whole code path was skipped.
This should clear up at least some of the negotation

author can't remember why it was there.
The CTS_SCSI_FLAGS_TAG_ENB remains in place, and makes sense, and is
checked all over the place.
The CTS_SPI_FLAGS_TAG_ENB was probably an attempt to distinguish
protocol and transport tag capabilities. At the very least this can
be confusing and prone to many bugs, so let's just assume that the
transport tag case just flows from the protocol (and vice versa)
for now.
and by only delaying when an RTC register is written to. The delay
after writing to the data register is now not just a workaround.
This reduces the number of ISA accesses in the usual case from 4 to
1. The usual case is 2 rtcin()'s for each RTC interrupt. The index
register is almost always RTC_INTR for this. The 3 extra ISA accesses
were 1 for writing the index and 2 for delays. Some delays are needed
in theory, but in practice they now just slow down slow accesses some
more since almost eveyone including us does them wrong so modern systems
enforce sufficient delays in hardware. I used to have the delays ifdefed
out, but with the index register optimization the delays are rarely
executed so the old magic ones can be kept or even implemented non-
magically without significant cost.
Optimizing RTC interrupt handling is more interesting than it used to
be because RTC interrupts are currently needed to fix the more efficient
apic timer interrupts on some systems. apic_timer_hz is normally 2000
so the RTC interrupt rate needs to be 2048 to keep the apic timer
firing on such systems. Without these changes, each RTC interrupt
normally took 10 ISA accesses (2 PIC accesses and 2 sets of 4 RTC
accesses). Each ISA access takes 1-1.5uS so 10 of then at 2048 Hz
takes 2-3% of a CPU. Now 4 of them take 0.8-1.2% of a CPU.
priority mutex implemented, it is the time to introduce this stuff,
now we can use umutex and ucond together to implement pthread's
condition wait/signal.
Fix things to use the LSI-Logic Fusion Library mask and shift names for
offset and sync, no matter how awkward they are, in preference to just
plain numbers.

and Daichi GOTO <daichi@FreeBSD.org> for submitting this
major rewrite of unionfs. This rewrite was done to
try to solve many of the longstanding crashing and locking
issues in the existing unionfs implementation. This
implementation also adds a 'MASQUERADE mode', which allows
the user to set different user, group, and file permission
modes in the upper layer.

Why the construct:

has a different packing than:
struct foo {

likely some subtle binding issue (eg before it says the struct itself

the thing it is in). Pointers to relevant documentation would be

sizeof ether_header is 2 * ETHER_ADDR_LEN + 2 (14) bytes long

On arm, this shows that struct ether_addr needs to be __packed.
The first condition muts be true for the bridging code to not dump core.
The second one appears to be implicitly relied upon by wi (but many
of the rids it sends down likely need __packed too to be safe) and
maybe others. It appears to not hurt anything.
