Okay, so what probably happened here is that before you applied the fix
to Network Manager to recognize the modem, it saw a USB ethernet
connection (just like when connecting a phone that tether its connection
directly) and then added it automatically to the wired connections list
(Auto usb0).

The reason why you haven't seen it before is because it is disconnected
until a special Ericssonl AT command opens it, and that happened after
the MBM plugin was associated with the modem. Probably the configured
wired connection entry was used instead of the MBM plugin handling the
usb0 Ethernet connection.

On a fresh installation containing those patches, the first step, auto
adding the usb0 to NM would probably not happen as it when NM first sees
it is associated with Ericsson MBM plugin.
