Sprint Aircard 341U modem issue

[dailijin]

Hi Aleksander,


Yes, I have merged RAWIP logic in qmi_wwan.c, but issue still happened. maybe I need to double check the RAWIP logic again.


The strange issue is when plugin the USB modem, the qmi status always is "connected", even I stop it by manual, but don't take effect. so I have no chance to execute command "echo Y > /sys/class/net/wwan0/qmi/raw_ip ". this maybe the reason. 


[root at tvupack]# qmi-network  /dev/cdc-wdm0 status
state file:/tmp/qmi-network-state_cdc-wdm0

Status: connected
