MM support for access technology change

Fri Jun 22 09:01:53 UTC 2018

Hey Jose,

Carlo & Daniele in CC, to see if they can shed some light.

If we get a disconnection report from the modem, MM disconnects bearer
object. MM will not automatically reconnect it, the upper layers
should request it (e.g. NetworkManager should request to re-connect).
That said, the problem here is the module returning that "Unknown
error (135500720)" on the reconnection attempt... no idea what that
is.
