If there's nothing under /proc/device-tree/, the card doesn't have an OF

I'm not sure - the card having an OF driver might mean it's a Mac card,
needing byte swapping, whereas a card with no OF driver would be a PC
card, needing no byte swap. Or vice versa. Asante probably never built PC
specific ethernet cards so the PCI vendor/device property could be used
instead of OF data. OF data is just easier to get at :-)
