Subdirectories would be nice, but Greg KH said earlier in a different context that there's an issue with them [1]. He went on to say tools like udev would miss uevents for the subdirs [2]. I don't know whether that's really a problem in this case -- it doesn't seem like we would care about uevents for files that do MSI-X vector assignment.
