I vaguely remember doing it on just the interface not working, but it was so long ago that I've forgotten the details.  A quick search on the web shows people configuring it in the same way.  Based on some discussions we've been having on the Linux netdev mailing list, I wanted to clean up the way we configure policing anyway.  I'll look into this while I'm doing that.
