I believe you need to fix that fpga to expose individual pci devices such that you can properly bind the individual devices to the expected drivers :) Seriously, who makes such a broken fpga device that goes against the PCI spec that way? Well, not so much as "goes against it", as "ignores all of the proper ideas of the past 20 years for working with PCI devices". thanks, greg k-h
