Hi Denis and all,
This patch series enables USB ethernet data path for gemalto modems
that support this feature, in particular for ELS81x devices.
Regards,
Sergey
v1 -> v2
- replace g_try_new0 by use g_new0
- drop patch with incorrect fix for modem init

Some gemalto modems provide USB ethernet interfaces for data path.
Implement gprs-context driver for such modems to send data via
USB ethernet rather than fallback to PPP.

Some gemalto modems, including ELS81x, may provide more than one
USB ethernet interface. Detect and save both network interfaces
rather than only the last one.
