Finaly get rid of the "forced" usage of VLAN2/WAN0 to an "active physical port"

[maverick3005]

There is still the "port move Problem" when i DON´t use the WAN-Port:

Setup:

WAN: DISABLED
Using only LAN1-Port from the Router and set the default Gateway for br0 in the Basic-Setup:

Looks at the pictures:

Situation: I MUST add the vlan2 to a physical Port for a correct Port-Order & Advanced VLAN-Setup.

And when i remove the VLAN2 from any active physical Port:

The LAN1 Port becomes WAN(0), which is not correct.

I gave you some infos because of the "needed" VLAN2, but VLAN2 is anyway always connected to port 5 or 8 on the CPU.
It is really nessassary to MUST connect it to a physical Port (tagged or untagged) ?

I asume some "Loops" needs to be checked? Basicly you must have a WAN-Vlan2 (on the CPU) - but do you really need it
connected to any physical port, too ?

Some tests with OpenWRT and DD-WRT in the past showed, that you can setup the switch/Router without to have a physical Port
connected to VLAN2 - and the units are still working without any problems (MIPS & ARM).

The actual situation prevent the "full" usage of the WAN-Port as a regulary "L2-Uplink Port" with ONLY the tagged&untagged VLANs you
really need - with the result you have all 4 LAN-Ports available for client connections - without vlans, you don´t need :-)

When an intelligent switch is here connected, it can run into a loop detection, or "untagging" of packets from the "VLAN2" to a wrong default-VID
on the switch itself. creating a dummy VLAN2 on the switch to catch broadcasts or other packets, coming from the SoC-CPU is not possible
on all switches (older Netgear reserves often VLAN2+3 for VoIP/Multicast usages and can´t be reconfigured by the user for other things...)
