Add an helper function to read the next valid VLAN entry for a given port. It is used in the VID to FID conversion function to retrieve the forwarding database assigned to a given VLAN port. Finally update the FDB getnext operation to iterate on the next valid port VLAN when the end of the current database is reached.
