The expected argument name would include the instance number, which is not only redundant in many cases (FOOETHn_n=arg.., "n" being the instance number) and conflicted with what netconf(8) does, but some drivers need to be able to see the arguments for all instances of its driver type--for example, dp8390 needs to know how many earlier instances have been configured to use PCI.
