later.

it automatically. The AHC_FORCE_PIO option wasn't having any effect because
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.

1. When a directory is renamed to an existing (empty) directory,
it is possible for the target vnode to become the source vnode
underneath you (because another process may complete the same
rename). It was assumed that this can't happen, and the bogus
errno EINVAL was returned. This was fairly harmless.
Fix: return ENOENT instead, as if the source directory was renamed
a little earlier.
2. The same metamorphosis is possible for non-directories. It was
assumed that this can't happen, and the code for handling "just
removing a link name" happened to be used. This would have worked
except for fatal bugs in the link name removal - the link name was
assumed to still be there, and a null pointer was followed.
Fix: check the result of relookup(). This fixes PR 1930.
Notes:
(a) POSIX seems to say that removing link names shall have no effect.
BSD (4.4Lite2 at least) does something reasonable instead.
(b) The relookup() may find a file unrelated to the original.
Removing this isn't correct. Consider 3 existing files A, B and
C, and concurrent renames: AB = rename(A, B), another AB, and
CA = rename("c", "a"). If rename() is atomic, then only the
following results are possible:
AB, AB (fails), CA: A = original C, B = original A, C = gone
AB, CA, AB: A = gone, B = original C, C = gone
CA, AB, AB (fails): A = gone, B = original C, C = gone
but ufs_rename() can give:
A,AB,CA,B (sorta): A = gone, B = original A, C = gone
This usually doesn't matter, since getting into a race is usually
an error.

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.

This involves expanding the support of the SEEPROM routines to deal with

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.
AHC_FORCE_PIO - This forces the driver to use PIO even on systems that
say they have memory mapped the controller's registers. This
seems to fix Ken Lam's problems. I've also placed this option
in the GENERIC kernel file so that we are guaranteed to install
even on these flakey machines.
AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on
the 398X controllers allowing a totoll of 255 non-paged SCBs.
This doesn't work quite yet, so this option is mostly here to
help 398X owners to experiment and give me feedback until this
works properly.
