I have a Macronix MX98713-based fast-ethernet card, and
it is a kind of DEC DC21140A-clone. Some time ago, Hannum had
fixed if_de.c to work with it, but it still had a problem
that duplicate packets might be produced.
Linux folks has fixed the problem and the information is available at
I have been trying to get the fixes into if_de.c, and (perhaps)
succeeded in getting the duplicate packets go away.
But some minutes after booting, the driver says:
de0: abnormal interrupt: transmit underflow (raising TX threshold 96|256)
de0: abnormal interrupt: transmit underflow (raising TX threshold 128|512)
According to Macronix's datasheets, such a situation isn't expected,
so we must fix something in if_de.c.
I'm neither a network expert nor a kernel expert, so I need help.
Someone has good idea about it? If needed, I'll post my dirty
