These chips require using the QMI protocol to enable anything but serial mode. They can, and should, still be configured using=20 AT commands on one of the serial interfaces. In particular, this driver does not support entering SIM PIN code or APN, which may be required before opening a connection. PIN can be set by using the standard AT+CPIN=3D"xxxx" command. APN can most likely be set by storing it in the default profile. patch 1 relaxes the cdc_ether CDC descriptor parsing in such a way that it will allow a vendor specific data interface if and only if the control interface also is vendor specific. This allows us to reuse the bind() function from cdc_ether for one of the possible device configurations we support patch 2 adds a new "subdriver" which exports the CDC encapsulated=20 command interface as a character device, and also to the calling driver. patch 3 adds the wwan driver, which uses the "subdriver" to configure the device via the Qualcomm MSM Interface (QMI) protocol encapsulated in CDC control commands. The actual network device is a minimalistic usbnet minidriver.
