Since the VF drivers can't really initiate link_up and link_down and
other VF drivers like i40e VF is not setting this callback. I think, it is
OK keep it as -ENOSUP(which is default).
Since Christain Acked on the fix on the usage of examples/ip_pipeline
application. Probably we are OK without this change.

Any thought from ethdev maintainers?
