Well, this is a known problem of the DEQNA. If the receive logic gets too
little to do, the transmit logic will die sometimes.
Paul Vixie posted a small program called deqnad a couple of years ago,
that followed old versions of Ultrix and that was supposed to keep
the on-board logic busy enough to not die.
I may some day put support for this in the driver. Please feel free to
give me hints :-)
