I don't like the "virtual" naming. In the past, we always tried to avoid
that for lower-upper devices like bond/team/bridge/others. Soft-device
was the used term. Please let the "virtual" term for vitrualization,
would that be possible?

How about "master_upper"? This is already widely used to refer to
bond/team/bridge/other master soft devices.

MASTER_UPPER_DEV_VLAN_FEATURES?
