No, I wasn't using this option. I tried it, but as you can see in the
following log dump, the driver immediately generated a lot of "Too much
work in interrupt" messages. I tried with several different settings for
max_interrupt_work (first default 20, then 50, 100, and 200) - but the
"too much work" messages kept comming, so I disabled the options and
max_interrupt_work parameters (back to the original settings), and they
went away.

The tests mentioned above was run with this driver - there doesn't seem
to be any problems with it on this card, when it is run without any
options (the last startup in the log dump), except that transmit errors
and timeouts still occur from time to time. I also tried the driver on a
machine with two 3c905 cards without succes - I will submit a bug report
to the netdev list in a moment.

The 3c590 replaced an Intel EtherExpress 16 ISA card this monday, and
generated the underruns from the beginning (I had never used this card
before), so I can't say what the cause is.
