a year before 1970 or a date beyond the time_t rollover, return -1 so callers
can detect it. Callers which expect the function not to fail just get a
different kind of rubbish from before.
a timer, as that will clear the timer instead. Pass in a safely in-the-past
value instead.

that bug needs to be fixed in timer_settime(), not here)

fail compilation here when NET_INET is not defined.
upon, because:
* it's MUCH quicker; no need to calculate the OBJDIRS of every library
we might require in every subdir.
(make obj drops from 21s to 3s on my system.)
* it's more robust when building to a fresh DESTDIR.
previous occurrences of MAXPATHLEN and FILENAME_MAX have been changed
to use MaxPathSize instead.
If MAXPATHLEN is not defined, then assume a default value of 1024
(this is primarily for use on the Hurd).
The reason for this is that some older platforms define FILENAME_MAX
to be 14, although MAXPATHLEN is 1024. On BSD-derived systems,
FILENAME_MAX And MAXPATHLEN are both 1024.
Bump pkg_install version to 20041226.
These modifications have been tested so far on a NetBSD-current bulk
build.
HPC1 does not mark transmitted descriptors like HPC3. We must
query the HPC1 chip to determine what it expects the next
descriptor to be, reclaim used ones, and restart if necessary. Each
revision's corresponding logic now lives in its own
sq_txring_hpc{1,3} function.
HPC1's transmit interrupt conditions also differ from HPC3, so
remove the INTR bits from descriptors when tagging new packets on
to the end of the chain in order to avoid unwanted interrupts.
Also, be extra careful when restarting the transmit ring. Since
transmit interrupts seem to be relatively slow on HPC1, sq_start
may be called while the DMA engine is quiescent, and before a
transmit interrupt is asserted. We cannot behave like HPC3, which
begins transmission from the first packet pulled from IFQ if the
DMA engine is quiescent as this would skip enqueued packets. It
appears that sq_start is never called before HPC3 asserts an
interrupt, which restarts the transmit queue at the appropriate
place. However, this often happens with HPC1 and we cannot assume
that if DMA is inactive in sq_start, then all previously queued
packets have fled the coop.
XXX Is there a similar race possible with HPC3?
HPC3 logic should remain functionally unchanged, and HPC1 should
finally work properly.
true on the transmit side, which appears to be significantly slower at
interrupting than HPC3.
XXX I used to be able to occasionally wedge the chip with
SQ_NTXDESC == 32, but have not yet been able to reproduce that
behaviour this evening with a larger value.
multiple seeq interfaces may exist. While here, add a few trace
actions, move the related macros into sqvar.h, and enhance the
sq_trace_dump output a bit.
better than txctl. Change from rtw_txctl/rtw_rxctl to
rtw_txsoft/rtw_rxsoft. Change the descriptor blocks' names to
match: rtw_txctl_blk becomes rtw_txsoft_blk. Change the member-name
prefixes for both software and hardware descriptors.
scheduling stuff: only handle SCHED_OTHER. Like the rest of the scheduling
stuff, this is for the benefit of code that can't be bothered to test against
_POSIX_THREAD_PRIORITY_SCHEDULING.
