Is the non-realtime driver a standard network driver, i.e. do you get
some new device which is configurable with ifconfig? Then it may not be
impossible to port the driver to realtime space (assumed that it is Open
RTnet uses a network driver model which is very similar to Linux. Our
Ethernet drivers are all ported from standard Linux. Take a look at
README.drvporting (rtnet/Documentation) to get an impression of what
steps have to be performed.
Furthermore, as FDDI would be a new media type, some internal extensions
of RTnet would probably be required - it's a bit difficult to say how
much work this would cause, but it should be feasible (most parts of
RTnet are already prepared for new media types).
