I believe I also mentioned that an internal name table set of routines is part of the linux-generic implementation of the ODP Traffic Manager APIs, so you could also review those to see if they might be a basis for generalization into the APIs that would be of use to you. But as Mike noted, the best way to kick off a discussion is to post an RFC showing the APIs you'd like to see. We can then discuss them as part of the normal weekly calls.
We'll also be having a number of "deep dive" sessions at the upcoming Linaro Connect SFO15 conference. If you plan to be there we can discuss your ideas and proposals there as well.
