Yes, this would be nice to have.

I suspect that this device is like other SDX55 devices we've seen, using
class/subclass/function to map the vendor specific functions
too. Dropping static interface numbers.  If correct, then the patch is
bogus and the interface numbers might change based on firmware version
and configuration.
