Hi Jeff,

I don't know if you received my previous mail, but I didn't see any
reply. That's why I'm resending my patches to the tulip driver. The
first patch makes this driver work on the Apple 100BaseTX card. The
second patch makes it work on MIPS boards and the NEC DDB5074 board.

Comments welcome,

Peter.
