Qualcomm suggests to use mux id values >= 0x81: though this does not
seem a strict mandatory rule, there are scenarios in which the usage of
a specifix mux id is required otherwise various kind of issues could
happen (e.g. call failure, limited throughput...).
A new ID_MM_INITIAL_QMAP_MUX_ID udev tag allows setting the first initial
mux id value to be used when creating the multiplexed data connection.

Add EUTRAN 106 band with an offset of 1000 since the current numbering

This new error code 'MM_SERIAL_ERROR_SEND_TIMEOUT' is used to make it easier
to distinguish why the transmission failed. Until now,
'MM_SERIAL_ERROR_SEND_FAILED' was always returned. This new error code is now
returned for an 'EAGAIN', as this is more likely to be a TIMEOUT.
This makes debugging easier, as a better error analysis is now possible.

For modems that need more time to respond to AT port probes (like some Telit devices,
and Cinterion-based Telit MV31/MV32) allow a custom number of AT probe tries on a
per-port basis for generic probing, or plugins that opt into this functionality.

The libmm-glib library, as well as the ModemManager headers installed
as part of the D-Bus service API, have always been LGPLv2+ licensed,
because we want users of the service to rely on them in their own
programs, even if they are proprietary.
Some files had an incorrect GPLv2+ header instead of the LGPLv2+ and
that was confusing. All public headers in the MM API have the correct
license text now.

According to 3GPP Rel17.2, TS 38104, band NGRAN-67 is supported.
Currently Qualcomm SDX72 chip support this band and MM would show

When a modem is not able to register to the network, MBIM and QMI indications
related to registration reports network rejection cause codes if request is
rejected by the network. This information is currently logged in the ModemManager
but not exposed outside of ModemManager.
These are the changes to define interface to expose network reject cause codes
over d-bus to the above layers which could be used by above layers to present
this information in a user friendly way.
Use configure_file() instead of custom_target(). This resolves the
following warning:
WARNING: Source item '/home/user/ModemManager/header-generator.xsl'
cannot be converted to File object, because it is a generated file. This
will become a hard error in the future.
When the modem is in a failed state because of a SIM-related error,
like a missing SIM, or if the modem is SIM-locked, allow the
Location interface to initialize and be enabled anyway.
This allows someone without a SIM to use the GPS, which does not
particularly require a phone subscription. It also allows
someone with a SIM to use the GPS even if the SIM is still
locked.
This patch was reworked, while keeping the original idea, by:
Aleksander Morgado <aleksander@aleksander.es>
Fixes#183
This new error type will be used to report errors in the carrier lock
operations performed through ModemManager.
They have a one to one mapping to the MBIM status specific errors.
Will be used to report operations that are not run as they have been
attempted too many times already.
Modems will usually report this kind of error e.g. when attempting to
connect with the same invalid APN too many times. The modem at some
point decides that it won't attempt the APN connection with the
network any more, so it returns this error to the caller right away.
Certain QMI or MBIM devices may not be able to support multiplexing at
all, or they may support a limited amount of links.
The new ID_MM_MAX_MULTIPLEXED_LINKS udev tag allows specifying the
maximum number of supported multiplexed links; e.g. 0 to report none
supported or 1 to report that one single multiplexed link is
supported.
On MBIM modems, when the SIM is ejected and re-inserted in a quick manner,
the state machine logic encounters a race condition and eventually, the
modem response for subscriber status is ignored. This change accounts
for that state transition without erroring out.
Fixes#672.
Users with QMI or MBIM capable modems may want to ensure that these
are never managed using plain AT commands, as that also involves using
PPP. This fallback to AT could happen if the QMI or MBIM port probing
fails for whatever reason.
The new `ID_MM_REQUIRED` udev tag allows specifying that a given port
MUST be successfully grabbed when creating a new modem object, or
otherwise the modem object will not be created at all (even if there
are other fallback control ports like AT that could have been used).
Use this tag with caution.
It is assumed that when this tag is used some other external process
may be monitoring the existence of the modem object in DBus as exposed
by ModemManager, and if it does not appear for any reason then the
modem would be reseted with some other mechanism (e.g. GPIOs, if
available). If no such mechanism to autorecover the modem is in place,
using this tag may leave the modem exposed in the kernel but ignored
by ModemManager.
This tag must be applied on the specific port for which the existence
and usability must be ensured.
E.g. flagging the MBIM port of the Fibocom L850 module as required:
$ vim /lib/udev/rules.d/78-mm-test.rules
ACTION!="add|change|move|bind", GOTO="mm_test_rules_end"

ATTRS{idVendor}=="2cb7", ATTRS{idProduct}=="0007", ENV{.MM_USBIFNUM}=="00", ENV{ID_MM_REQUIRED}="1"
LABEL="mm_test_rules_end"
$ sudo udevadm control --reload
$ sudo udevadm trigger

This new method allows querying the modem for information about the
current serving cell(s) as well as any other neighboring cell that may
be found.
The information for the cells is given in an array of dictionaries,
where each element of the dictionary is a new dictionary itself.
Each cell type has a different set of properties that may be given in
the dictionary, and some of those properties in each type are also
applicable under certain conditions (e.g. only applicable to the cell
if it's a 'serving' cell instead of 'neighboring').
The API documentation explains in detail what is expected in each
case.
The 'allow-roaming' setting should be considered deprecated for 3GPP
devices that support the new 'roaming-allowance' setting, which is
much more detailed (as it allows to differentiate between partner and
non-partner networks) and may also be stored as part of a profile.
In 5G capable devices, which can support multiple types of access
types (either 3GPP or non-3GPP), the UE may request to use a 3GPP
access type exclusively, prefer a 3GPP access type, or just report no
preference.
When supported, this field may also be part of the settings that can
be stored as part of a profile.
A new set of property+method is added to be able to configure the 5G
specific registration settings, initially defining the support for the
MICO mode.
The property name starts with "Nr5g" instead of "5gNr" because of the
limitations imposed by the GObject type system on how properties with
numbers can be named.
We keep the 'WHITELIST-ONLY' filter type name still as an option in
--filter-policy=[POLICY], but deprecated and with the better
'ALLOWLIST-ONLY' replacement suggested from now on.
