This patchset allows individual PMDs to specify their preferred parameter values, and if so indicated by an application, for them to be used automatically by the ethdev layer. This RFC/V1 includes per-PMD values for e1000 and i40e but it is expected that subsequent patchsets will cover other PMDs. A deprecation notice covering the API/ABI change is in place.
