I'm fond of the DEC 21x4x 'Tulip' family, and I've been using three or four
of those 4-port 10/100 cards in firewalls without incident.  Note that I'm
running FreeBSD 4.5, but we'd used Debian and Redhat (or MacOS X DP2) with
these cards several years ago.  Anyway, the point is that I'd expect these
cards to be supported and work well under a new Linux kernel.

I believe these were OEM cards from either Dell or maybe Apple, but in case
the specific chipset and PCI identification information would be useful,
here it is:
