by udev, maybe.  However, it won't be detected by oFono without a
properly setup udev rule.

Code from add_mbm for reference:

        } else if (registered == 0 &&
                        (g_str_has_suffix(desc, "Minicard Network
Adapter") ||
                        g_str_has_suffix(desc, "Mini-Card Network
Adapter") ||
                        g_str_has_suffix(desc, "Broadband Network
Adapter") ||
                        g_str_has_suffix(desc, "Minicard
NetworkAdapter"))) {

Your modem (at least according to your earlier dmesg log) is reporting
the ethernet device as: Mobile Broadband Network Device
