[Nicolas RENAULT]

Hi,

I'm new with libqmi so I hope that my question is not too noobiest :

I try to use qmi-network and I have this ( I test with /dev/dcd-wdm0 to 
but it's raw-ip device not 802-3 ) :

-----------------------------------------------------------------------

APN=websfr     ( french op, it is the good one for the sim card , i try 
it on smartphone )

questions :
* '/sys/class/net/wwan1/qmi/raw_ip'  does not exist
