Hi Kenneth,
In the end this is up to David Miller of course, but I'd say we are
better off not introducing any ABIs for ODP prematurely.
We are talking about very generic statistics data, and you should
already provide them for the ethernet driver using the standard
interfaces.
I have not seen any discussion about adding an ODP subsystem for
the Linux kernel, or what the API will be, but I think we should
not export any interfaces from a particular device driver directly
but always go through a common layer here and use an extensible
interface that can be implemented by everyone.
The API has not been part of a release yet, so I'd say we should
remove it for now. Once we have a net/odp/ directory, we can
add a driver-independent implementation there and call it from
the hisi driver.
