[RFC PATCH v2 0/1] Introduce UCI support for configuring DSA VLAN filter rules

[Josh Bendavid]

"1. Have VLAN devices on top of vlan-enabled bridges to define hotplug
ops where applicable, so LAN could be a plain VLAN interface switch0.1
instead of its own bridge."

By this you mean that the creation of the switch0.1 device will
trigger automatically through the hotplug op
"bridge vlan add dev switch0 vid 1 tagged self" or its equivalent?
