When the utility sends a request it expects a response type message,
but does not explicitly check for it. When a device stays idle for
some time, it switches into a sleep mode, and notifies the utility with an
identification type message. In some configurations the device only sends
this identification message when triggered by the utility, in this case by
the request message. What the utility gets is two messages at the same time -
an identification and a response. When it tries to decode former it obviously
fails, because it is not what it expected.

Change the current ip-family option to set the IP Family Preference
TLV in the Start Network command, and add a separate set-ip-family
option for the Set IP Family command. This is done to match how
the autoconnect and set-autoconnect options work.
Older modems don't support the Set IP Family command, and they
should use the IP Family Preference TLV. On the other hand, newer
modems, e.g., from Huawei, don't respect that TLV, and require the
use of the separate Set IP Family command.

All MBIM integer fields are 32bit little endian. So we need to convert
then all on big endian systems.

Many newer modems from Sierra Wireless includes a feature known as
"FCC Authentication". The basic idea is that the radio is kept in
low power mode until the driver has told the firmware that it is
OK to switch it on. This is done with a vendor specific QMI DMS
request with no input or output TLVs.
The "Set FCC Authentication" request is required for any modem with
the feature enabled. Which includes most newer Lenovo branded Sierra
Wireless modems based on Qualcomm chipsets, like for example the
EM7455.
Sample session with an EM7455 in MBIM mode and the FCC Authentication
feature enabled:
$ umbim -d /dev/cdc-wdm0 -n radio
hwradiostate: on
swradiostate: off
$ uqmi -m -d /dev/cdc-wdm0 --fcc-auth
$ umbim -d /dev/cdc-wdm0 -t 2 radio
hwradiostate: on
swradiostate: on

Many Qualcomm based devices offer a QMI service when running in MBIM
mode. This is useful for a number of requests which have no MBIM
counterpart.
This implementation is very basic, simply wrapping the QMI requests
in an MBIM command. It is up to the user to make sure that the MBIM
command sequence is valid, using a mix of umbim and uqmi requests.
umbim must be used to send "OPEN" before uqmi can issue any MBIM
requests. Example:
1. use umbim to open the session, using the '-n' option:
$ umbim -d /dev/cdc-wdm0 -n caps
devicetype: 0003 - remote
cellularclass: 0001
voiceclass: 0001 - no-voice
simclass: 0002
dataclass: 003C
smscaps: 0003
controlcaps: 0001
maxsessions: 0008
deviceid: 0145820007xxxxx
firmwareinfo: SWI9X30C_02.08.02.00
hardwareinfo: EM7455
2. use uqmi to send an MBIM request, using the '-m' option:
$ uqmi -m -d /dev/cdc-wdm0 --get-serving-system
{
"registration": "registered",
"plmn_mcc": 242,
"plmn_mnc": 1,
"plmn_description": "TELENOR",
"roaming": false
}
3. use umbim to close the open session, using the '-t X' option:
$ umbim -d /dev/cdc-wdm0 -t 2 caps
devicetype: 0003 - remote
cellularclass: 0001
voiceclass: 0001 - no-voice
simclass: 0002
dataclass: 003C
smscaps: 0003
controlcaps: 0001
maxsessions: 0008
deviceid: 0145820007xxxxx

It is a convention under CMake to suffix variables in the FIND_LIBRARY
calls with _LIBRARY. Added _library suffix to json, blobmsg_json and
ubox variables.
|
|
CMake will search for include paths via FIND_PATH() of the following
libraries: libubox, blobmsg_json and json. This allows to build uqmi
when the dependencies are in non-standard locations by specifying
respective _include_dir variables.

Adding --get-current-settings switch which can be used to query
ip-settings among some other useful data obtained from remote end when
connected.
This is mainly useful with modems which do not provide a dhcp server for
nameserver or ip-information (especially in ipv6 networks).

This patch adds support for (optionally) specifying ip family via a
command- line switch. The switch sends respective "Set IP Family" WDS
message to qmi-device before actually connecting.
Using this switch allows connecting to ipv6 enabled networks or networks
with dual-stack support with the appropriate hardware (dongle and FW
with ipv6 support) and configuration (AT+CGDCONT reporting ipv6 or
ipv4v6 capability).
Help text:
--ip-family <family>: Set ip-family for the connection (ipv4, ipv6, unspecified)
Usage example for ipv6:
uqmi -d /dev/cdc-wdm0 --set-client-id wds,<cid> --start-network <apn> --ip-family ipv6
Dual-stack usage example:
uqmi -d /dev/cdc-wdm0 --get-client-id wds
uqmi -d /dev/cdc-wdm0 --set-client-id wds,<cid-1> --start-network <apn> --ip-family ipv4
uqmi -d /dev/cdc-wdm0 --get-client-id wds
uqmi -d /dev/cdc-wdm0 --set-client-id wds,<cid-2> --start-network <apn> --ip-family ipv6

If 7 bit message encoded on 8 bit cells has one last bit occupying
whole byte it need to be padded with 7 zero bits. To not mistake
these last 7 bits with a character with code 0 (@) we need to check
length from User Data Length field and not rely on actual length
of received data. An example can be message "abcdefg" encoded
as "61 f1 98 5c 36 9f 01", it is decoded as "abcdefg@".
