Modems which are using qmi do not reply on the 1st sync but they do
on subsequent. Sometimes uqmi is hanging - even when using an early
dummy access to unlock the modem. To always guarantee a proper
initialisation, running or hanging uqmi processes must be stopped
before. All uqmi calls have now a timeout option -t to avoid hanging.

Configure the PLMN and APN to the modem. This is required in cases,
where either the SGSN or GGSN does not permit the selection of IPv4v6
pdp type.
Previously, the modem always tried to establish a dual-stacked PDP
context regardless of the configured PDP type in uci. As this setting
can not be parameterized when creating a WDS context, configure it to
the modems internal list of profiles. This way, the PDP type is taken
into account when creating the WDS context.

The PLMN selection was reset when calling network-register, thus
rendering the sepcific selection of a carrier unapplied.
Set the PLMN selection after executing network-register. This seems to
cause the modem to re-select the carrier eventually.
That being said, qmi does allow the parameterization of the
network-register to include dpecific PLMN settings, however this is
currently not implemented in uqmi.

Set the RAT preference before attaching. This handles cases better,
where a network might be available but not with the preferred RAT.
If RAT is changed to a non-available RAT after attach, QMI does not fail
with missing registration but with failing to establish a PDP session.

Increase the wait time before polling the connection state for the first
time.
Depending on the prior state of the modem, the first poll might still
return a connected state. The script then tries to establish a PDP
session, which subsequently fails as the modem by then is in scan state.
Increasing the wait-time to 3 seconds mitigates this from happening.

On some network-triggered disconnections the UIM state might end up in
"illegal". This prevents the modem from attaching to any network in
non-restricted service modes.
Detect this state and reset the SIM card. This way, the modem can attach
to networks again.

Failing the registration does not necessarily mean we can not bring this

Modems which are using qmi do not reply on the 1st sync but they do

this parameter. So qmi.sh is now invoking an early dummy access to

If dual-stack configuration is in use, and dhcpv6 option is set, do not start

Add two new "v6apn" and "v6profile" properties, to support split-APN
dual-stack onfiguration. This extends the existing ipv4v6 PDP type,
allowing simultaneous connection to two distinct APNs,
one for IPv4 and one for IPv6.
The parameters override existing 'apn' and 'profile' respectively,
if set, but only for IPv6 part of the connection.
If unset, they default to their original values, constituting a standard
IPv4v6 setup.
If a different APN is set for IPv6, a corresponding profile MUST also be
configured, with a different ID, than the IPv4 profile, for example,
profile 2.
Both APNs must match ones configured through QMI or through 'AT+CGDCONT'
command.
Example configuration in UCI:
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
option autoconnect '1'
option pdptype 'ipv4v6'
option apn 'internet'
option v6apn 'internetipv6'
option profile '1'
option v6profile '2'
Corresponding profile configuration:
AT+CGDCONT?
+CGDCONT: 1,"IP","internet","0.0.0.0",0,0,0,0
+CGDCONT: 2,"IPV6","internetipv6","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

Modems used in ZTE mobile broadband routers require to query the data
session status using the same CID as one used to establish the session,
otherwise they will report the session as "disconnected" despite
reporting correct PDH in previous step. Without this change, IPv6
connection on these modems doesn't establish properly. In IPv4 this bug
is present as well, but for some reason querying of IPv4 status works
using temporary CID, this however seems noncompliant with QMI

Setting the plmn to '0' (auto) will implicitly lead to a (delayed)
network re-registration, which could further lead to some timing
related issues in the qmi proto handler.
On the other hand, if you switch back from manual plmn selection
to auto mode you have to set it to '0', because this setting is
permanently "saved" in the wwan module.
Conclusion:
If plmn is configured, check if it's already set euqally in the module.
If so, do nothing. Otherwise set it.

The control device /dev/cdc-wdm0 is not available immediately on the
D-Link DWR-921 Rev.C3, therefore the wwan interface fails to start at

This patch alters /lib/netifd/proto/qmi.sh to wait for
network.wwan.delay earlier, before checking for the control device,
instead of just before interacting with the modem.
One still has to use network.wwan.proto='qmi', as the "wwan" proto
performs that sort of check before any delay is possible, failing with a
"No valid device was found" error.
