I've always been sceptical of this. When physical systems have a large
number of NICs, it's via multiple functions, not a bunch of PCI bridges.
Actually a lot of multiport PCI cards are in fact single or dual NICs
behind PCI bridges.

Can you send me pointers to the qdev documentation? How can I use it? Will
it allow us to scale above the 32 PCI limit?

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
Thanks. Does this work for e1000 as well?
Also, does it support pci hotplug?

Haven't tried. I don't know how various e1000 drivers would react.

No, but that's fixable down the road.
