net: dsa: Be aware of switches where VLAN filtering is a global setting
On some switches, the action of whether to parse VLAN frame headers and use that information for ingress admission is configurable, but not per port. Such is the case for the Broadcom BCM53xx and the NXP SJA1105 families, for example. In that case, DSA can prevent the bridge core from trying to apply different VLAN filtering settings on net devices that belong to the same switch.
