The web UI lists physical and VLAN interfaces and takes a VLAN uplink as
a device name (enp2s0.1001); it has IPv6 checkboxes for the WAN and each
LAN. router-setup asks whether to create VLANs before WAN and LAN are
picked, and whether to enable IPv6. --config-only writes the
configuration without installing, which the setup test uses for a PPPoE
uplink on a VLAN.
