"I've been having a problem running the patches [committed to current]
installed with the COMPAT_LINUX_THREADS option along
with the VM_STACK patches I did. I'm not sure what
the problem is, since it seemed to work before.
In any event, the attached patch fixes the problem for
me. While I've had no report of problems from anyone
else, possibly it would be wise to commit the patch
until the problem is found.
Also, there was some left-over junk in the linux_misc.c
file from some earlier work I did. The attached patch
cleans that up too."

to (ab)use a side effect of comparam() and partly because I didn't
understand what the reset was doing (it flushes the fifos). This
turned out to be more than a cosmetic problem. Flushing the fifos
quite late is good for discarding input that arrived while the line
state was being initialized, and in the cy driver it also seems to
reduce a problem with input that arrived long ago during the previous
close (the UART loses sync too easily and for too long).

ethernet driver.
The BUGS section is still impressive, but the driver seems to work for
me now. Disclaimer: i haven't been able to test this under -current
so far (but it compiles, and the notebook it's intended for can now be
updated to -current more easy than before). Don't be afraid of the
many #ifdefs on __FreeBSD_version in the imported file; i want them in
the repository on the vendor-branch so other people can also manually
integrate it into older systems. I'll clean it up on the -current
branch in a followup commit. The vendor-banch version right now
supports systems back to 2.2R.
This driver should be layered upon ppc(4), but i currently have no
idea how to do this.
Eventually i'll further develop the driver to also support the more
modern RTL 8012 success, which seems to be present in a number of
cheap pocket ethernet adapters these days. Right now, i doubt it will
run with the 8012 without any changes.
Finally a big Thanks! to RealTek for promptly providing me with
documentation and with the source code for the 8012 pocket driver upon
request. I wish all vendors were that cooperative!.

ethernet CRC along with every received frame (the driver turns on
PN_NETCFG_NO_RXCRC, but it was frobbing the wrong bit).
almost works properly. Unfortunately, there is no way to flush
the rx fifo without resetting the channel, which also flushes the
tx fifo. We avoid resetting even when both fifos need to be flushed,
since resetting seems to cause the rx to lose sync if it is done
while data is arriving.

Attempt to determine (at mount time if not done so already) via density code
whether a device should default to fixed mode or not. Attempts to set to

Similarly, the '2 filemarks at EOM' quirk is now determined (or attempted to
be determined) via density code. Some as yet not entirely tested code for
coping with 2FM@EOD position is now also in place.
hardware is interrupt-driven to a fault and sending a BREAK requires
mode switching. Always running in the BREAK-capable mode as in PR 8318
would double the overhead for sending \0's.
