> There seem to be some undesirable behaviors related with PVID.
> 1. It has no effect assigning PVID to a port. PVID cannot be applied

> 2. FDB entries learned via frames applied PVID are registered with
> VID 0 rather than VID value of PVID.
> 3. We can set 0 or 4095 as a PVID that are not allowed in IEEE 802.1Q.
> This leads interoperational problems such as sending frames with VID
> 4095, which is not allowed in IEEE 802.1Q, and treating frames with VID
> 0 as they belong to VLAN 0, which is expected to be handled as they have
> no VID according to IEEE 802.1Q.

> (1/4)(2/4): Fix 3rd problem.

> (4/4): Fix 2nd probelm.
