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

[Felix Fietkau]

Hi,

I would like to propose an alternative configuration format that is
structurally close to your proposal, but more generic in that it is not
tied to DSA directly but configures bridge vlans instead.

Here's the converted form of your example:

config device switch0
	option name switch0
	option type bridge

config bridge-vlan vlan1
	option device switch0
	option vlan 1
	option ports 'lan1 lan2=t'

config bridge-vlan vlan2
	option device switch0
	option vlan 2
	option ports wan

config bridge-vlan vlan5
	option device switch0
	option vlan 5
	option ports 'lan2=pt lan3'

config bridge-vlan vlan8
	option device switch0
	option vlan 8
	option ports 'lan2=t lan4'

config bridge-vlan vlan11
	option device switch0
	option vlan 11
	option ports 'lan2=t lan4=t'


Changes:
  - The device is created as a netifd bridge
  - Bridge vlan sections should always refer to the bridge instead of
automatically be applied to the first one
  - Use = instead of . to mark tagging modifiers. "." is already used
for vlan interface names and reusing it here creates ambiguity.
  - Allow specifing pvid as a modifier instead of needing to create a
separate port section.

The section names are optional, I chose to put them in to make it easier
to modify the sections from scripts

What do you think?
