Benjamin Lindqvist 28ac1f70bf drivers: modem: gsm_ppp: proper attach retry
In a previous commit, a check was added to ensure modem was properly
attached to packet service before initializing PPP. Failure to perform
this check can lead to the dreaded 'NO CARRIER' issue.

While this is a nice idea, the implementation was lacking because when
the check failed, the entire modem initialization procedure was
restarted from square one. For modems/bearers that were slow to attach,
this is potentially disastrous. The proper solution is to loop only the
'AT+CGATT?' part until it succeeds, or fails N times.

This commit implements this looping behavior (using the work queue).

Benjamin Lindqvist 4626a577c4 drivers: modem: gsm_ppp: Kconfig for autostarting ppp
Autostarting PPP is far from controversial. There are many, many reasons
someone could have for wanting to control exactly when PPP starts. Power
management, NET_EVENT race condition avoidance and any application not
requiring constant and instant use of networking just to name a few.

This commit introduces a Kconfig setting, GSM_PPP_AUTOSTART, which
controls whether gsm_ppp should connect and initialize PPP at boot. It
is set to "y" as default to minimize surprises for legacy code.

Benjamin Lindqvist 254c126236 drivers: modem: optional factory reset at modem boot
Some modems, under some conditions, have a tendency to get stuck without
a connection due to cached state. We have observed this on some Simcom
LTE modems after large cellular outages. The modems are unable to escape
their cached state for some reason unless they're factory reset (or a
cache clearence is forced in some other way).

This commit allows for the modem to be factory reset at each boot. This
minimizes dependencies on external state by ensuring each power-up is as
similar as possible.

Thomas LE ROUX f360718d0b drivers: modem: Fix PDP context management for BG9X
The PDP context might be active.
If that's the case, the AT+QIACT command returns an error.
It's then not possible to succeed at setting up the module.

Furthermore, we apply the logic described in the Quectel Documentation :
- If there is an issue 3 consecutive times on activating/deactivating
the context, we restart the module.
- If the AT+QIDEAT command returns an error, we restart the module.

This PR is bug-fix aimed.
We leave parameterization of context ID for future enhancement.

Bilal Wasim 503a70a40a drivers: modem: Add support for quectel bg95
Adding support for Quectel BG95 Modem offloaded driver
to zephyr.

The driver currently implements only the
client side functions of the "socket_op_vtable", and
so cannot be used for cases where Zephyr acts as a
server. Moreover the driver only supports TCP for now.

Looking through the guides, the same driver should be
usable for BG96 (and other modems) except for the modem
boot-up sequence. Hence its named as "bg9x" instead of
"bg95".

Tested extensively with Zephyr acting as MQTT endpoint
and publishing / subscribing data to / from an MQTT
broker.
