Calling on all 4G/QMI Experts! wan IP refresh issue

The modemmanager: report network initiated disconnections to netifd patch handles that. MM now has a dispatcher script that gets called on every connection/disconnection event; and for the disconnection ones, a report to netifd is done notifying that the underlying connection is down.

Unless I'm missing something, the reconnection would be done if the wwan configuration in /etc/config/network is set to automatically connect.
