Actually, I'm working on it. Base part has been done. Currently, just
adding more commands. But, I cannot release the code until 3 month
after the release of the product.

By the way, libqmi is just for QMI commands (controlling the modem).
Tx/Rx data packets go though PPP. That's because qualcomm refused to
release that part of information.
