Research direction

Start by reproducing the FM350-GL setup described with mmcli -b 1 and compare the DHCP-provided IPv6 configuration with the DNS values available through the AT command. Trace how netifd receives and applies the modem's DHCP configuration; done means the reported DNS servers are present in the resulting interface configuration.
