Dual-port nic support?

Does Linux support any dual-port network cards?  Intel has their PRO/100+ Dual Port Adapter, but they only claim Linux support for their PRO/1000 Gigabit Adapter.  I am simply too low on PCI slots on my home machine and need to consolidate.

Thanks for ANY help.

Allow me to suggest the D-Link DFE-570TX Quad Channel Server Card (quad 10baseT / 100baseTX, NWay auto-sense).  I have just installed two of these in a system that needed lots of interfaces.  You will need the most current release of Don Becker's tulip driver (0.91); it may be in the current 2.2.x kernel, but I just replaced the 0.89h tulip.c in my 2.2.5 kernel with a copy from Becker's site at www.cesdis.nasa.gov (exact URL is in the file you are replacing, which is /usr/src/linux/drivers/net/tulip.c).  (The card, like other PCI quad fast ethernets of which I am aware, has a PCI bridge chip and four Tulip-family PCI fast ethernet chipsets (in this case, 21143's, which is why you need at least tulip.c 0.91).)

Once I updated tulip.c, tweaked Space.c to add Ethernet devices beyond the first 8, and rebuilt my kernel, it worked without a hitch.  I strongly recommend building the tulip driver as a module and running "modprobe tulip" from within /etc/rc.d/init.d/network to auto-probe for all available interfaces.  More advice on multi-port Ethernet cards, including pointers to other vendors, can be found at http://www.freelabs.com/~whitis/hardware/quartet.html.

I purchased these cards at $249+tax apiece from Pacific Computer Supply, www.pacificcs.com.  They arrived overnight.  Can't complain!
