I've been wondering about how to implement the MBIM QMI feature in uqmi/umbim for a while. This is the only method we know for sending the "Set FCC Authentication" request in MBIM mode.
But I didn't just want to add support for that single use case. The completely generic solution in libqmi/libmbim has been a great success, allowing arbitrary QMI commands to be send to these modems when they are in MBIM mode. This is useful for so much more than FCC Auth. So I wanted a similarily generic solution for uqmi too. This is what I came up with. As you can see, it does not change anything in umbim. But it still depends on umbim (or similar MBIM tools) to create a proper MBIM session, as uqmi can only send one specific MBIM command: QMI requests. umbim must therefore open the MBIM session before any uqmi request can succeed. The second patch adds the "Set FCC Authentication" support. There are no TLVs associated with this request, so it is pretty simple.
