MC7430 modem issue

[dailijin]

Hi Aleksander,


Thanks your help, I have merged all patchs into my qmi_wwan source code, also merged the usbnet patch, and now I can compile qmi_wwan driver successfully based on kernel 3.8.0.


After implemented the new driver, I can fetch QMI command response and do QMI connection successfully via qmi-network. but always can't get IP. currently I use the libqmi version is 1.10.2, Should I need to upgrade it to the newest one?


below is the log:
