The ModemManager codebase has been ported to support Basic Connect v2
messages as defined in MBIMEx v2.0, so at this point we can now switch
to use it by default whenever possible.
We're going to enable the Microsoft extensions by default, and in
order to properly parse the notification messages, we'll need to know
which is the currently agreed MBIMEx version.
So, pass down the MbimDevice to every notification parser. Not all of
them will need it, so just for completeness.
Telit modems that require hexadecimal number when specifying 4G bands
also reply to #BND=? command with a 4th parameter <LTE_band_ext>
(e.g. LM940, LM960, LN920, FN980).
On the other hand, modems that require decimal number when specifying 4G
bands only return 3 parameters to the same command.
It is then possible replace the detection of ext_4g_bands via UDEV tags
with an inspection of BND=? reply.
Since the 'wwan' subsystem addition to the qcom-soc plugin, the rules
to say a modem is handled by this plugin are too broad, and the plugin
attempts to support any kind of device exposed by the WWAN subsystem,
not just those from Qualcomm SoCs.
Update the plugin to require a new ID_MM_QCOM_SOC udev tag that is set
in the plugin udev rules, given that these rules already check for the
expected SoC drivers (bam-dmux, ipa, qcom-q6v5-mss).
The generated objects in `libmm-glib` are include in
`libmm_glib_dep` one by one to avoid the link to the generated
library that is included as a whole in `libmm-glib`.
meson includes a way to include partial objects of a dependency by
using the `partial_dependency` method, so by taking advantage of it
almost all objects are included.
We cannot just return without completing the GTask. If we see the
support check method failed, just keep on with the state machine so
that the GTask is completed in the FAIL_IF_UNSUPPORTED step.
Also, don't assume GError is set if FALSE is returned. This is the
only kind of async method where we allow this right now.
In some modems, the modem's radio can be ON when no SIM card is present.
In this case, the modem is in failed state, and the host cannot set the
power state to LOW. Since we we will allow the host to set the power to
LOW, we should allow it to set it back to ON.
