For some, e.g. Intel e1000, it does not matter. You can have it appear on a completely different function number in the guest as compared to the host. For others, e.g. bge, as you discovered, the function numbers in the guest and host have to match. Also, PCI requires that for a multi-function device, function 0 must be present. So, it is not possible to assign a device to a function > 0 without also having some device present at function 0. Hope that helps.

I suspect that this is because the function number of the virtual PCI
device and the physical PCI device are different.
Could you try to use the following instead: -s 2:1,passthru,3/0/1
Alternatively you could try assigning the physical PCI device 3/0/0:
-s 3:0,passthru,3/0/0
