It probably does not work with 2.3.x code; but then  -  I  never  got
lucky with any 2.3 code :-(

Right. See our version of the sources in

Works fine in a couple of systems based on 860T and 860P  CPUs,  with
Level One 970 and 9880 and similar PHY's.

If your hardware does autoconfiguration you can omit most of the  PHY
recognistion  stuff;  otherwise enable it, but then you must assign a
PHY interrupt.

Me too (in an ISDN router).
