The slave ethernet device may be capable of filtering ethernet packets based on VLAN ID. This requires that when the VLAN interface is created over an HSR/PRP interface, it passes the VID information to the associated slave ethernet devices so that it updates the hardware filters to filter ethernet frames based on VID. This patch adds the required functions to propagate the vid information to the slave devices.
