Florian Fainelli e47112d9d6 net: dsa: b53: Fix VLAN usage and how we treat CPU port ... We currently have a fundamental problem in how we treat the CPU port and its VLAN membership. As soon as a second VLAN is configured to be untagged, the CPU automatically becomes untagged for that VLAN as well, and yet, we don't gracefully make sure that the CPU becomes tagged in the other VLANs it could be a member of. This results in only one VLAN being effectively usable from the CPU's perspective. Instead of having some pretty complex logic which tries to maintain the CPU port's default VLAN and its untagged properties, just do something very simple which consists in neither altering the CPU port's PVID settings, nor its untagged settings: - whenever a VLAN is added, the CPU is automatically a member of this VLAN group, as a tagged member - PVID settings for downstream ports do not alter the CPU port's PVID since it now is part of all VLANs in the system This means that a typical example where e.g: LAN ports are in VLAN1, and WAN port is in VLAN2, now require having two VLAN interfaces for the host to properly terminate and send traffic from/to.
