Yes, thank you. I have today confirmed this using a Sierra em7455. I configured IPv4v6 in the bearer. Using a Deutsche Telekom SIM it reported IPv4v6 and using a Vodafone SIM card it reported IPv4. Actually this is what I want, as it gives a clear indication if v6 (or v4 or both) configuration should be attempted or not. Unfortunatly, as I wrote in my last mail ModemManger ignores this hint for the sake of supporting "broken" devices. The comment in mm-bearer-mbim.c mentiones a Vodafone Surfstick K5160. Maybe Aleksander or Dan have a suggestion on how to solve this while still maintaing support for the mentioned device. Could writing back the ip_type only if the configuration has ip_type Ipv4v6 be a solution? Is there a mechanism for device specifc quirks I could employ? Or should I maybe add a new attribute in the bearer which only reflects the ip_type reported back by the modem?
