/*
* The way this plugin works is following:
*
* powered -> SubscriberIdentity or Online = True -> gprs, context ->
* attached -> netreg -> ready
*
* Depending on the modem type, this plugin will behave differently.
*
* GSM working flow:
*
* When a new modem appears, the plugin always powers it up. This
* allows the plugin to create a connman_device. The core will call
* modem_enable() if the technology is enabled. modem_enable() will
* then set the modem online. If the technology is disabled then
* modem_disable() will just set the modem offline. The modem is
* always kept powered all the time.
*
* After setting the modem online the plugin waits for the
* ConnectionManager and ConnectionContext to appear. When the context
* signals that it is attached and the NetworkRegistration interface
* appears, a new Service will be created and registered at the core.
*
* When asked to connect to the network (network_connect()) the plugin
* will set the Active property on the context. If this operation is
* successful the modem is connected to the network. oFono will inform
* the plugin about IP configuration through the updating the context's
* properties.
*
* CDMA working flow:
*
* When a new modem appears, the plugin always powers it up. This
* allows the plugin to create connman_device either using IMSI either
* using modem Serial if the modem got a SIM interface or not.
*
* As for GSM, the core will call modem_enable() if the technology
* is enabled. modem_enable() will then set the modem online.
* If the technology is disabled then modem_disable() will just set the
* modem offline. The modem is always kept powered all the time.
*
* After setting the modem online the plugin waits for CdmaConnectionManager
* interface to appear. Then, once CdmaNetworkRegistration appears, a new
* Service will be created and registered at the core.
*
* When asked to connect to the network (network_connect()) the plugin
* will power up the CdmaConnectionManager interface.
* If the operation is successful the modem is connected to the network.
* oFono will inform the plugin about IP configuration through the
* updating CdmaConnectionManager settings properties.
