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 :-) Bjørn
