[v2: Editorial changes suggested by Sergei Shtylyov] These modems use the Qualcomm MSM Interface (QMI) protocol for management of their CDC ECM like wwan interface. This driver is perfect for exporting the protocol to userspace. The created character device will be indistinguishable from a common AT command based Device Management interface, so userspace applications must do some intelligent matching on the USB device.
