The switch barely supports traffic I/O, and it does that by repurposing VLANs when there is no bridge that is taking control of them. Letting DSA declare this netdev feature as supported (see dsa_slave_create) would mean that VLAN sub-interfaces created on sja1105 switch ports will be hardware offloaded. That means that net/8021q/vlan_core.c would install the VLAN into the filter tables of the switch, potentially interfering with the tag_8021q VLANs. We need to prevent that from happening and not let the 8021q core offload VLANs to the switch hardware tables. In vlan_filtering=0 modes of operation, the switch ports can pass through VLAN-tagged frames with no problem.
