It is good to make drivers more complete and compatible, but unless
the virtual driver has some useful data I can't see the point of providing
these functions in this case. The base infrastructure (rte_ethdev) should
deal with by returning not supported error (or all zeros); rather than
creating more code in other drivers for no real gain.
