TULIP: Fix for 64-bit MIPS 

From: Jim Gifford <maillist@jg555.com>, Grant Grundler <grundler@parisc-linux.org>, Peter Horton <pdh@colonel-panic.org>

With Grant's help I was able to get the tulip driver to work with 64 bit
MIPS.

[VAL: I'm happy with the 1.5 ms max delay; it doesn't seem excessive.]
