D-Link card: tx underrun

[Peter Haag <peter@pyxis.ch>]

Dear all,
We have a D-Link 4way PCI ethernet card. In normal operation, it works 
perfectly well.
But under heavy network load we got tons of error messages ( see below ). 
The transfer speed
is rather bad until the buffers somehow settled. The box runs
OBSD3.3 stable.

Any ideas how to fix that, or fix fix the buffers to a size, which works.
