Hi Ulf,

That wasn't the question :-)

I am quite happy with the Znyx 314 I have here, but I am looking for a
solution (possibly 100baseT) with two ports.  I won't go into the
reasoning.

I am aware of a number of vendors supplying two- and four-port DEC Tulip
based Ethernet solutions, but I have no idea which ones are supported.

Comments from Matt Thomas have not always been encouraging, and there is
hard coded support in the driver for the Znyx 314 (look for ZX314 in the
source).

On the other hand: the de driver definitely is a cool driver for a cool
bit of inexpensive hardware!  (Just so nobody considers this as criticism.)
