Changes since v2: * Revert callback data setup changes; the original model was fine so this amounted mostly to churn and, unfortunately, ended up introducing memory leaks * Use ofono_gprs_context_deactivated in the detach_shutdown path instead of modifying release_active_contexts() * Add support for roaming registration state
Original cover letter follows: LTE is different from other 'GPRS' technologies in that a default bearer always gets set up when the modem registers to the network. Ofono has some support for this and this series tries to set this up for QMI modems. The key to understanding this series is to understand that QMI modems do not automatically enable the network interface when connecting to an LTE network, even though the default bearer is already set up. A call to "start network" needs to be made in order to allow packets to flow. So the jist of this series is: i) detect network registration to LTE network ii) call ofono_gprs_cid_activated iii) in read_settings, start by calling "start network" ...and then there are some other adjustments in the series to make this all work. I've tested this with my EC21, both on LTE and UMTS networks. It all seems to work, including moving out of network connectivity and bringing the modem repeatedly online/offline. One open question at this point: * What happens if the connection manager calls deactivate_context on the default bearer context? I don't see that any other drivers guard against this, and the QMI driver will happily stop the network interface even though the default bearer is still up in the background.
