I have not received all my parts from ebay yet or I would test this directly. I've got a 4 port broadcom nic on the way and it occurs to me I might need a motherboard that supports bifurcation. It's specifically

LENOVO 90Y9355 Broadcom Quad-Port 1GbE PCIe Network Card BCM95719A1904G High

Anyone know offhand if I just bought a card I can't use? It's going in a system I know doesn't support bifurcation but I can't find anything one way or the other about this card.

you only need bifurcation if you need to split PCI lanes for something like multiple nVME drives, a PCI card does not work like that. was that an advice someone game you?

Doesn't need bifurcation, it's just four lanes straight to the BCM5719 chip, looks like it does support SR-IOV if that's something you care about.
