I think that is true by definition following Taras's logic from a thread
a few weeks ago. The rational was that that helpers are users of the API
to add higher functionality for an application to use, they don't help
the implementation.

However that breaks IPC I think, I have not read the latest patch, but
that wants to use odph_ring.h - unless IPC is a helper,  but I thought
it was part of ODP.

I was thinking of helpers as a next layer on top of ODP which provides
some additional functionality, but as Bill noted some helpers may not
use ODP API and can be called even before ODP init. Maybe it worth to
call such helpers in a special way to distinguish them.

There is no restriction for helpers to be called from both sides:
implementation and application. Like we have IP header structure used
by linux-generic and applications.
