Select this if you want to use an LG Electronics 4G/LTE usb modem

interface exposed by the modem firmware. To establish a connection
you will first need a userspace program that sends the right

* The device has a CDC ACM port for modem control (it claims to be
* CDC ACM anyway) and a CDC Ethernet port for actual network data.
* It will however ignore data on both ports that is not encapsulated
* in a specific way, any data returned is also encapsulated the same
* way. The headers don't seem to follow any popular standard.
*
* This driver adds and strips these headers from the ethernet frames
* sent/received from the CDC Ethernet port. The proprietary header
* replaces the standard ethernet header in a packet so only actual
* ethernet frames are allowed. The headers allow some form of
* multiplexing by using non standard values of the .h_proto field.
* Windows/Mac drivers do send a couple of such frames to the device
* during initialisation, with protocol set to 0x0906 or 0x0b06 and (what
* seems to be) a flag in the .dummy_flags. This doesn't seem necessary
* for modem operation but can possibly be used for GPS or other funcitons.
