Implement read_settings function to get configuration for automatic
contexts. AT^SWWAN command activates PDP context unless it has been
already activated automatically, and then starts DHCP server in the
ME. So AT^SWWAN command should be run for automatic context as well
in order to obtain IP settings from the ME.
This commit also fixes the issue uncovered by the added support for
automatic contexts: as per modem specs, AT+CGACT context should not
be reused for AT^SWWAN. Though that worked for some reason when
automatic context was reactivated without proper deactivation.
Note that in both cases success code is reported to the core before
AT^SWWAN response. This is because the ME waits until DHCP negotiation
has finished before sending the "OK" or "ERROR" result code.
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.
This atom uses the URC ^SLCC to monitor the call status, as well as
incoming calls.
Note the use in the atom of the variable GemaltoVtsQuotes: this is
needed to support future modules, as of today not yet available in the
plugin.
There are a large number of files in the tree that define _GNU_SOURCE
despite not actually using features hidden behind this flag. This patch
removes all these definitions in one fell swoop...
The driver vtables are read-only structures. This patch declares them as
'const' allowing the compiler to (optionally) put them in the RELRO
section. RELRO pages may be marked as read-only by the linker after
the relocations have been done ensuring that they aren't inadvertently
or maliciously altered at runtime.
Add a new location-reporting driver for Gemalto Cinterion modems based
on telit implementation + use it in gemalto plugin. It supports
activation of GNSS engine (Request) with command AT^SGPSC. This driver
is tested on PHS8. NMEA frames are accessible on /dev/ttyUSB1.
