    Too bad I didn't read this patch before and now it has been already applied.

    The above two prop names should have # in front of them. Examples seem to 
be correct. Some words about the downstream bus wouldn't hurt too.

    The above two props should have # in front of them as well. Examples seem 
to be correct.
