Sorry for the late feedback here, but a question: Would this be better as
two patches rather than just one? It seems there are two changes here - one
to cpfl just adding a new device id for the driver to use, and a second,
seeming unrelated change, to idpf to identify PF vs VF. The new defines
used in CPFL are not used (unless I missing something) in IDPF driver and
vice versa, meaning the two changes seem distinct?
