Interesting! I tried to add some QMI handling in the kernel a few years
ago, but was thankfully voted down. See
https://www.spinics.net/lists/netdev/msg183101.html and the following
discussion. I am convinced that was the right decision, for the client
side at least. The protocol is just too extensive and ever-growing to be
implemented in the kernel. We would be catching up forever.

Note that I had very limited knowledge of the protocol at the time I
wrote that driver. Still have, in fact :-)
