to enable IP forwarding, use sysctl(8). Also did the same for IPX,
which involved inventing a completely new MIB from whole cloth (which
I may not quite have correct); be aware of this if you use IPX forwarding.
(The two should never have been controlled by the same option anyway.)
Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.
Update comments and fix formating.
Pass struct ahc_data*'s to functions instead of unit numbers.
Take advantage of the quad word alignment of SCB fields.
Adapt to new sequencer changes:
1) Waiting scb list no longer has a tail.
2) Fill the message buffer as appropriate during a parity error.
3) Count all of the SGs involved in a residual instead of just
the current one.
The reset/abort code still needs a lot of work.

outb 0x80 instead of 0xc80. The top byte is truncated anyway, and 0x80
was what was intended.
enough nodes for the number of ports on the last module, not the number
of ports _total_ that the driver is managing...
Submitted by: Robert Sanders <rsanders@mindspring.com>
Nobody in our regular source tree, or in the non-distfile part of the
ports tree does use /dev/io anyway, so this might be replaced by
another scenario some day.
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches. The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.
gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes. Does anyone
disagree?
gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header. This
hack will do until then. (Use gprof4 -u to examine the results
of non-statistical profiling.)
config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.
kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'. `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.
we can see if it's a small distance beyond the end, or way out. This may
give some clues as to whether it is being caused by something coalescing
the transfers in spite of the bounce buffers, or simply because of buffer
corruption. (The BT driver seems to occasionally get hit by from this too,
except that it does not trap the transfer, and the system panics later
with vm_bounce_page_free.) This "event" usually happens to me during a
savecore (on the rare occasion that a kernel coredump is actually taken
after a crash - the lack of kernel core dumps is another problem...).

bcopy:
Be smarter about handling overlapped copies and only go backwards if it
is really necessary. Going backwards on a P6 is much slower than forwards
and it's a little slower on a P5. Also moved the count mask and 'std'
down a few lines - it's a couple percent faster this way on a P5.
libkern.a are now specified by listing their source files in
files.${MACHINE}. The list is machine-dependent to save space.
All the necessary object for each machine must be linked into the
kernel in case an lkm wants one.
