So, we may have modems with multiple /dev/cdc-wdm ports, like Ericsson modems,
where only 1 of them is MBIM. With the previous logic, we would probe all
/dev/cdc-wdm ports for MBIM as soon as one of the ports was handled by the
cdc_mbim driver. That is totally not optimal, as we are already know that they
are not MBIM (not handled by cdc_mbim).
Instead, fix the logic to just probe for MBIM or QMI if the actual driver
managing the port is MBIM or QMI.
It's been observed that some modems occasionally take a long time to
power down (which may be due to some shutdown sequence that involves
communicating with network). This patch increases the timeout for
powering modem up and down from 10s to 20s.
It's been observed that modems may take a long time to disconnect from
the network under certain network conditions. This patch increases the
timeout for the MBIM_CID_CONNECT set command in the disconnect sequence
from 10s to 30s.

Instead of returning success and the PIN type + PIN status + Remaining attempts,
this modem returns a plain ERROR_PIN_REQUIRED error, so try to handle that...
Standard GPS setup (raw/nmea) will both enable the GPS module and take full
control of the GPS port. This prevents other processes from reading the NMEA
traces from e.g. a tty. In order to handle this, a new 'unmanaged' GPS location
source is introduced, which will just enable/disable the GPS module, without
reading anything from the GPS port. Of course, both raw/nmea and unmanaged
setups cannot be enabled at the same time.
The first case, with no error, needs to check that there was no original error.
Currently, if an error occurs and the resulting NwError is parsed correctly, the
case split treats it as a no-error case.
Commit 55e40ea b1ae81a in libmbim ("libmbim-glib: add additional GMM
cause codes to MbimNwError") added one more GMM cause code to
MbimNwError. This patch maps that to MMMobileEquipmentError.
This patch requires libmbim >= 1.9.0
When trying to disconnect bearer, if the modem responds with
MBIM_STATUS_ERROR_CONTEXT_NOT_ACTIVATED, take it to mean that the bearer has
already been disconnected.
Subclasses may need to know which IP families were used for the setup
so they can return the correct IP configuration. We can't just use
the MMBearer default_ip_family becuase that isn't the family that
was actually used during the connection.
Commit b1ae81a in libmim ("libmbim-glib: add additional GMM cause codes
to MbimNwError") added additional GMM cause codes to MbimNwError. This
patch maps some of those MbimNwError to MMMobileEquipmentError.
This patch requires libmbim >= 1.9.0
Update PCO handling code such that it conforms to the latest VZW network
behavior. This includes updating the way we mark a SIM as provisioned.
In the old network, only provisioned SIMs can attach to the network.
Now, unprovisioned SIMs can attach and connect to the network.

If a task is marked as defer-until-suggested (e.g. a wwan port) and there was
already a 'best' plugin set in the parent device, use it to complete the
deferred task.
This may happen in e.g. MBIM devices if the WWAN port arrives later than the
already probed /dev/cdc-wdm character device.
A device like this shows up briefly while the Sierra EM7345 is booting:
P: Vendor=8087 ProdID=0716 Rev= 0.00
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=500mA
I:* If#= 0 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=(none)
E: Ad=83(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
We do have a driver identifying this as an "Infineon Flashloader"
device. It is not a modem in any case, and should be ignored.

If the initialization of the Modem3gpp / ModemCdma interface fails, the
modem transitions to the FAILED state. But since the Modem interface is
already initialized and exported over DBus, it is possible to invoke the
Enable method on the Modem interface. This patch changes
MMBroadbandModem to report an error if one tries to enable the modem in
the FAILED state instead of raising an assertion.
This patch refines the access technology updates on a MBIM modem by
observing the MBIM_CID_PACKET_SERVICE notifications in addition to the
MBIM_CID_REGISTER_STATE notifications. If a MBIM_CID_PACKET_SERVICE
notification indicates the highest available data class, the current
access technology is updated to reflect that. Otherwise, the access
technology is updated according to the available data classes indicated
by a MBIM_CID_REGISTER_STATE notification.
If the APN was empty (implying that the modem/network should choose
the default APN) this caused an assertion in libqmi. Just don't
set an APN if we aren't given one.
The 3s wait before opening a MBIM port is not necessary for handling a
delayed response to the MBIM OPEN messages. mbim_device_open() already
retries the MBIM OPEN message when the MBIM device does not respond.
We make many USB virtual COM port devices, none of which are modems.
ModemManager's automatic attempts to access those devices can cause
problems.
That might change in the future, so we have left two potential
future product IDs off of the blacklist.
This patch modifies MMBearerMbim to update the MTU value in the bearer
IPv4 and IPv6 config property when such information is available in the
MBIM_CID_IP_CONFIGURATION response.
This patch removes an extra invocation of g_simple_async_result_complete
on the result associated with each command context in the command queue
when mm_port_serial_close clears the queue. It also changes the code to
complete the results in idle, which avoids a nested invocation of
mm_port_serial_close. That could happen if the completion of the result
calls mm_port_serial_close again (e.g. via at_command_context_free,
at_sequence_context_free in mm-base-modem-at.c). The nested invocation
of mm_port_serial_close could create undesirable effects (e.g. the
assertion on open_count > 0 fails in case of a forced close).
Subscriber information like MSISDNs / MDNs may not be readily available
when MMIfaceModem queries for it during modem initialization.
This patch modifies MMBroadbandModemMbim to subscribe to the
MBIM_CID_SUBSCRIBER_READY_STATUS notification and update the
'OwnNumbers' property of the Modem interface when the information
becomes available.
libmbim renames 'MBIM_CID_DEVICE_SERVICE_SUBSCRIBER_LIST' to
'MBIM_CID_DEVICE_SERVICE_SUBSCRIBE_LIST' to be consistent with the MBIM
specification. This patch updates MMBroadbandModemMbim accordingly.
