Correction: They were under WITH_VIRUALPORT (which has a configure option
and a check for IFLA_VF_PORT_MAX).

We will need a check for IFLA_VF_MAX here.

I think I will try putting this under defined(IFLA_VF_MAX). This should
cover IFLA_VF_MAC and IFLA_VF_VLAN I think. If you have any other
suggestions let me know.
