This parameter is intended to allow new kernels to work with old LKM binaries,
provided the revision ID is incremented whenever the PCI LKM interface is
changed. The revision ID does not at all protect against changes in data
structures accesses by the driver.
Disabled the DMA byte counters - I had it this way originally and this is
the recommended setting.
Set crscdt to CRS only (0) since this is what it should be for an MII PHY.
Also fixed some comments.

to search the QINFIFO to remove any possible command that is waiting
otherwise our abort request may not be held up still waiting for the
first command to complete.
I/O port address of most devices is not contiguos, a return value of
probe routine is not so useful for detecting conflict. The return
value was too big, and kernel sometimes detected conflict even though
two devices are not conflict in I/O address between them.

Fix a few panics during error recovery:
1) Stupid mistake in the "no SCB match handler" where I was using the wrong
variable (busy_scbid instead of scb_index).
2) Unbusy the target of an abort request if the command we are trying to
abort is an untagged transaction. If we don't, we get a fatal NO_MATCH_BUSY
condition which "should never happen".
3) When an abort completes, turn off ahc->in_timeout or else the next timeout
will hit the protective "scb timesout again" panic.
4) Fix a typo that caused the requeued "abort" SCB to have its TAG_ENB and
disconnect bits to be cleared (missing ~) so that devices would complain
about overlapped commands.
Be sure to turn off the unexpected busfree interrupt after we do a bus
reset since we are expecting the bus to go free in that case.
Return XS_TIMEOUT instead of XS_DRIVERSTUFFUP in certain scenarios. XS_TIMEOUT
allows for retries, XS_DRIVERSTUFFUP does not.
Allow commands with SDTR and WDTR negotiation to be tagged. The SCSI II spec
says that you probably should not do this for fear of hitting bogus devices.
The driver did this in the past for almost two years without any problem,
and not doing it causes problems during error recovery to a tag capable device
as the number of openings is higher than two and we'll start sending it
tagged commands causing "overlapped commands attempted" type errors. The
real fix needs to happen in the generic SCSI layer which can limit the
number and type of transactions to a device during error recovery efficiently.
Give ourselves at least 100ms to perform a request sense instead of relying
on the original timeout to be long enough to complete this new command as
well as the one that generated the condition.
Removed some redundant code.
host DMAs. The additional test to ensure that the DMA has stopped is also
unnecessary since we've already waited for the DMA to complete.
Update my copyright for the new year.
(since T_DIRECT just incidentally happens to be equal 0). This causes
more harm than it would do good. Instead , get it at the uk driver.

is set.
The result is that diverted packets that are being forwarded
will be diverted once and only once on the way in (ip_input())
and again, once and only once on the way out (ip_output()) -
twice in total. ICMP packets that don't contain a port will
now also be diverted.

Closes PR#2461.
create a skeleton device driver.
one for a real device and the other for a pseudo device.
they each take one argument which is the name (prefix) for the driver.
they add the new file to the /sys tree and add appropriate config files
etc for a build.
hopefully others will build on this so that we get
1/ these drivers improved and the shell scripts
improved in how/where that hook the new code in.
2/ similar tools for providing skeletons for other
modules (I'm tempted to do a VFS filesystem skeleton :)
please take a look and fix anything that maybe should be added.
they compile and link fine,
but I think I wouldn't trust them, as faar as RUNNING yet :)
(well they really wouldn't do very much being skeletons..
we need to add PCI and EISA skeletons as well
followed by a SCSI driver skeleton.
library with a shared object dependency that contained alias symbols,
the linker incorrectly counted the number of symbols that would be
written, resulting in a fatal internal error. Since our libc now
contains some alias symbols (in "net/res_stubs.c"), this was
sufficient to tickle the bug: "ld -Bshareable foo.so -lc". To
fix it, I moved the accounting of alias symbols to a later point
in the processing, where it is possible to count only those symbols
that will actually be written to the output file.
This fix is well-confined to affect alias symbols only. I have
tested it with a full "make world". I am going to merge it into
-2.2 after a few more days of living with it in -current.
