6 ms is quite long:
I added a reset into tx_timeout, and that function should not take more
than 1 ms or so.
Did you find something about the delay in the documentation? Is it
possible to poll for reset completion?

I know that the winbond-840 chipset resets in 4 pci cycles - perhaps the
via-rhine is also fast?

That's expected, my patch fixes another bug.
The NIC now recover from "Tx timeout" messages. ksa confirmed that, but
there is still a delay of a few seconds. I'll try to fix that.

Did you run via-diag before or after loading the via-rhine module?
