The 'hso' driver tags Icera-based modems' proprietary protocol port
as a DIAG port, but since they aren't Qualcomm-based, it's not
a DIAG port. Just turn off AT probing and let QCDM probing
fail the port instead of assuming it's a DIAG port.
Instead of getting the port type hints while grabbing each probed port, we now
run a custom init operation in the probing which already gives us the port type,
and therefore allows us to completely skip port probings.
Also now added hints for 'Diag' (QCDM) ports and AT/'Modem' ports (I guess it's
the one for PPP if we don't have a net port, which is unlikely anyway in HSO).
This makes the probing of an Option/HSO modem almost instant.
Both the ModemManager daemon and the mmcli will now include `libmm-glib.h' only.
We also handle two new special `_LIBMM_INSIDE_MM' and `LIBMM_INSIDE_MMCLI'
symbols, which if included before the `libmm-glib.h' library allow us to:
* Don't include the libmm-glib high level API in the ModemManager daemon, as
the object names would clash with those in the core.
* Define some of the methods of helper objects to be included only if compiling
ModemManager daemon or the mmcli.
Different ports of the same modem may get handled by different drivers. We
therefore need to provide a list of drivers (new `Modem.Drivers' property with
signature 'as') instead of just one (removed `Modem.Driver' property with
signature 's').
$ sudo mmcli -m 0 | grep drivers
| drivers: 'qcserial, qmi_wwan'
There's no real point in maintaining a separate `MMPlugin' interface, as all the
plugins will inherit from `MMPluginBase', so just merge them and simplify
everything.
Before this, we only exported the modem to DBus when all ports were organized,
in order to make sure that we select as primary port the one we really want and
not the first AT port grabbed. Given that to get all the ports organized we also
needed to wait to get all the ports grabbed, we can now also defer the creation
of the modem object until all the ports get grabbed. This allows us to create
different types of objects based on the ports available (e.g. we can now create
QMI-supported modem objects if we see a QMI port around).
The `physdev' stored in the probe is the sysfs path of the parent device, that
owning all ports. We need to build the setup file path using the port's sysfs
path instead.
