[PATCH 0/2] Add Suspended property to GPRS

Hi All, The following patches add the Suspended property to the GPRS atom and implement it in the isimodem driver. The property is opt-in for drivers that have the relevant information. The value is read-only and defaults to false. GPRS class B modems are not able to support simultaneous GPRS data transfer with other services, such as voice call or SMS. GPRS services may also be suspended if the network does not support DTM, if the modem has poor network coverage, or because of signalling procedures such as location or routing area updates. While GPRS services are suspended, the modem remains attached to the cellular network and all PDP contexts remain established. Data transfer, however, is not possible. Some discussion: The isimodem driver will currently suppress changes in the property value for short-lived suspended states caused by SMS transmission or other signalling. It would also be possible to do the suppression in the oFono core in a generic way. Alternatively, all the state changes and their reasons could also be exposed to oFono clients. However, my feeling is that the information might not be available in a sufficiently coherent way from the different modems. Anyway, I'm open to suggestions.
