NAPI-ized tulip patch against 2.4.20-rc1

[Ben Greear <greearb@xxxxxxxxxxxxxxx>]

Here is a patch that makes Tulip support NAPI.  The vast bulk of these
changes come from Robert Olsson's ftp site, I just pieced them together.

It works good on my 4-port Tulip NICs, better than the default
driver at least (no, I never tried the old HW-Mitigation option).


This patch will also make use of Robert's skb-recycle patch if it's
been applied, but through #ifdef magic, it should also work w/out
that....

Enjoy,
Ben
