Actually a lot of multiport PCI cards are in fact single or dual NICs
behind PCI bridges.

Thanks. Does this work for e1000 as well?
Haven't tried. I don't know how various e1000 drivers would react.
Also, does it support pci hotplug?
No, but that's fixable down the road.

It's all below. You just have to create a PCI device and mark the
multifunction flag to on and then assign it a PCI addres
Thanks. Does this work for e1000 as well?
