[tulip] Linksys PCMPC200v2 Transmit Timeouts

I have somewhat similar problem with linksys LNE100TX 4.1 card. or two
problems, both tx related but otherwise probably unrelated.
one problem is the tx timeout message, it does not go away unless I
re-load drivers (and no transmission goes through). this problem is
fixed either by patch I've got from Dan Hollis or by latest test driver:
tulip.c:v0.92p 11/28/2000 Written by Donald Becker <becker@scyld.com>
the other problem is that there is a lot of carrier errors (as
reported by ifconfig) and I also get tx errors but only for given
connection, the card works continuously. there are no problems on rx.
it looks like this problem is caused by card thinking it's 100Mb, half
duplex while the card on the other end of crossover cable thinks that
it's 100Mb FULL duplex (IMO full duplex is right, why would it be half
duplex? the card is definitely able to do full duplex (tested by loading
ms win)).
Donald said that this problem should befixed by the tst driver
mentioned above but it is not (in my case). Does anybody else have
similar problems? Any other comments/ideas?
I am not sure how this is related, your card might use completely
different chips, I don't know (it looks like quite a mess).
