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.
