Hi Reinhard,
thanks for your input.

I will try this soon, hopefully tomorrow.

For qmuxd there is QMI_QMUX_IF_GET_VERSION_INFO which generates a
QMI_CTL_GET_VER_INFO_MSG_ID towards the baseband processor. So I think
that also shouldn't be a problem.
My immediate goal is to find a way to establish a packet data connection
(via WDS) from the Linux processor on a non-android qmuxd-based MDM
chipset. The bit question I've been wondering about is how to identify
the network device via which the actual IP data of the PDP context will
be received (e.g. rmnet0). I was hoping the WDS Start Nework Interface
message contains something like a port ID. I found some referencs to a
iface_handle and a data_call_origin field.
If the QMI request is issued on the control pipe associated with one
particular network interface, I geuss it is implicit that at least the
default is to transport the data over that interface, too.
The next question is how to put different PDP contexts in different
network devices... But let's see how far I get in terms of the basics,
first.
Regards,
Harald
