> VF was not able to send tagged traffic when it didn't have any VLAN
> interfaces and VLAN anti-spoofing was enabled.
> Fix this by allowing VFs with no VLAN filters to send tagged traffic. After VF
> adds a VLAN interface it will be able to send tagged traffic matching VLAN
> filters only.
> 
> Testing hints:
> 1. Spawn VF
> 2. Send tagged packet from a VF
> 3. The packet should be sent out and not dropped 4. Add a VLAN interface on
> VF 5. Send tagged packet on that VLAN interface 6. Packet should be sent out
> and not dropped 7. Send tagged packet with id different than VLAN interface
> 8. Packet should be dropped
