MC7430 modem issue

[dailijin]

Hi Bjorn,


It seems that the MC7430 hardware  is different with MC7304, so the work mode is also different, we should modify qmi_wwan driver to support raw-ip for MC7430 modem dialing, Right?


I have merged the three patchs, but compile qmi_wwan always fail based on kernel 3.8, the error as below:
tvupack qmi_wwan # make
make -C /lib/modules/3.8.0-23-generic/build M=/data/danner/qmi/qmi/driver/qmi_wwan modules
make[1]: Entering directory `/data/danner/current_kernel_source/linux-source-3.8.0'

I notice the structure "dev_attr_raw_ip" actually is not in the three patchs,  which file define it?


Thanks

I check the data format which is 'raw-ip', and can't be changed via qmi command, this maybe why I can't get IP. because I remember MC7304 and MC7354  can work before only after I set '802-3' as data format for them.
