Maybe it would be more efficient to make smi->ops->is_vlan_valid optional?

I'm not going to lie, the realtek_smi_ops VLAN methods seem highly cryptic to me. Why do you do the same thing from .enable_vlan4k as from .enable_vlan? What are these supposed to do in the first place? Or to quote from rtl8366_vlan_add: "what's with this 4k business?"
Also, stupid question: what do you need the VLAN ops for if you haven't implemented .port_bridge_join and .port_bridge_leave? How have you tested them?
