pppd timed out or didn't initialize our dbus module

[Przemyslaw Galazka]

Thanks for input.

After changing logging level to debug for ppp demon, I can tell that it is
trying to go through LCP phase and get IP address but ModemManager has
configured 20 seconds timeout for this.
It seems like NetworkManager is killing pppd in the middle of session,
always after 20seconds.

How we can change that timeout then? It seems that is is hardcoded in
