probing: sync with NM to decide whether a WWAN port is really modem-controlled
Submitted by Aleksander Morgado

There are devices out there (e.g. Huawei E355) which expose a WWAN port, flagged as WWAN by the kernel, but which doesn't require any further setup via any control protocol.
MM could have a new 'probing' property to let users know that a device is being probed, and if the probing ends without MM creating a modem for a given WWAN port, NM could take over the control of the port and try IP setup on it directly as if it were an Ethernet interface.
