[vortex] Problems with TX underruns in 2.4.9

[James Yonan]

I'm having problems with TX underruns when I download files using FTP over a
100BaseT ethernet connection (eth1) from a windows machine on the same
ethernet segment.  Basically, a multi-file FTP download goes for about one
minute then hangs.  The connection comes back a few minutes later with
messages in the log file such as:

Dec 26 15:19:58 boulder kernel: eth1: Transmit error, Tx status register 90.
Dec 26 15:19:58 boulder kernel: eth1: Transmit error, Tx status register 90.
Dec 26 15:21:56 boulder kernel: eth1: Transmit error, Tx status register d0.

So far I've tried making max_interrupt_work bigger and commenting out
"#define tx_interrupt_mitigation 1" in 3c59x.c but the problem persists.
The problem is, in fact, 100% reproducible.

Note that this machine has three NICs.  eth0 is a cyclone card.  eth1 & eth2
are vortex cards.  eth1 is where I am seeing the problem

I'd appreciate any help you can offer.  Anyone else with similar symptoms?
Is there a patch or some driver parameter that can be tweaked to fix this
problem?  (see below for system details)

Thanks,
