If the VF is privileged/trusted it can do as it may please including but not limited to hogging resources and playing unfair. But if the VF is not privileged/trusted it still can add some number (8) of MAC and VLAN addresses. Other restrictions with respect to Port VLAN and normal VLAN still apply to not privileged/trusted VF.
