Subject: [net-next PATCH v2 1/4] net: Move functions for configuring traffic
 classes out of inline headers

The functions for configuring the traffic class to queue mappings have
other effects that need to be addressed.  Instead of trying to export a
bunch of new functions just relocate the functions so that we can
instrument them directly with the functionality they will need.
