Correct, IFLA_VF_PORT_PROFILE is not in the kernel yet.  The kernel patch is
be discussed on the kernel netdev mailing list.  The most recent discussion
is on ways to merge VDP and CDCP into what I've posted for
IFLA_VF_PORT_PROFILE.

I'll send out another libvirt patch once the kernel discussions are final.
