negative-logic flags (flags 0x01 and 0x02 for npx0, defaulting to unset = on).
This changes the default from off to on. The options have been in current
for several months with no problems reported.
Added a boot-time negative-logic flag for the old I5886_FAST_BCOPY option
which went away too soon (flag 0x04 for npx0, defaulting to unset = on).
Added a boot-time way to set the memory size (iosiz in config, iosize in
userconfig for npx0).
LINT:
Removed old options. Documented npx0's flags and iosiz.
options.i386:
Removed old options.
identcpu.c:
Don't set the function pointers here. Setting them has to be delayed
until after userconfig has had a chance to disable them and until after
a good npx0 has been detected.
machdep.c:
Use npx0's iosize instead of MAXMEM if it is nonzero.
support.s:
Added vectors and glue code for copyin() and copyout().
Fixed ifdefs for i586_bzero().
Added ifdefs for i586_bcopy().
npx.c:
Set the function pointers here.
Clear hw_float when an npx exists but is too broken to use.
Restored style from a year or three ago in npxattach().

uses one or the other. This required some changes to the ahc_reset()
function, and how early the probes had to allocate their softc.
Turn the AHC_IN/OUT* macros into inline functions and lowercase their names
to indicate this change. Geting AHC_OUTSB to work as a macro doing
conditional memory mapped I/O would have been too gross.
Stop setting STPWEN in the main driver and let the PCI front end do it
instead. It knows better.
Add the clearing of the QOUTQCNT variable during command complete processing
in the SCB paging case.
Go back to doing unconditional retries for the QUEUE FULL status condition.
This is really a kludge, but the code to handle it properly is on the SCSI
branch and will not make it into 2.2.

This allows the user to add modify syscons's configuration flags using
UserConfig that will allow older/quirky hardware (most notably older IBM
ThinkPad laptops) to work with the standard boot kernel.

handlers if interrupts are nested more than a few (3) deep. This
only reduces the maximum nesting level by 1 with the standard
drivers unless there is a related bug somewhere, but can't hurt
much (the worst case is returning to hoggish interrupt handler like
wdintr(), but such interrupt handlers hurt anyway).
Fixed a previously harmless race incrementing the interrupt nesting

the PCI probe code didn't include this file.
Fix some problems with the new sync and wide negotiation code. First off,
go back to async transfers by using a message reject again. The SCSI II and
III spec indicate that if a target's response to an initiater does not suit
(i.e. its too low), then performing a message reject is the appropriate
response. If, on the other hand, the initiator begins the negotiation and
we want to go async, we will send back an SDTR message with a 0 period and
offset.
Also fix a really bad negotiation problem caused by a missing "break". This
would usually hit people that had "smart" wide devices that immediately
attempt sync negotiation after a successful wide negotiation.

This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.
Especially the 3c59X support should be pretty stable now.

mappings with mlock. This problem only occurred because of the
quick unmap code not respecting the wired-ness of pages in the
process. In the future, we need to eliminate the dependency
intrinsic to the design of the code that wired pages actually
be mapped. It is kind-of bogus not to have wired pages mapped,
but it is also a weakness for the code to fall flat because
of a missing page.

Try to cater better for early receive interrupts.
This involves expanding the support of the SEEPROM routines to deal with
the larger SEEPROMs on these cards and providing a mechanism to share
SCB arrays between multiple controllers.
Most of the 398X support came from Dan Eischer.

Clean up some more type bogons I missed from the last pass.
Be more clear when handing the NO_MATCH condition. NO_MATCH can also
happen when the sequencer encounters an SCB we've asked to be aborted.
