problem of allocating contiguous buffer memory in general, but
make it much more likely to work at boot-up time. The best
chance for an LKM-type load of a sound driver is immediately
after the mount of the root filesystem.
This appears to work for a 64K allocation on an 8MB system.

3COM 3C592 Etherlink III EISA,
3COM 3C590 Fast Etherlink EISA,
3COM 3C900 Etherlink XL PCI and
3COM 3C905 Fast Etherlink XL PCI.
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.

- `slstat' with no args dumped core.
- `slstat unit' always failed with a "sysctl linkspecific" error.
- the usage message was nonstandard.
Fixed old bugs:
- missing prototypes, Wformat errors, and other lint.
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.

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

but it is also a weakness for the code to fall flat because
