+ Select this if you want to use an LG Electronics 4G/LTE usb modem
+ called VL600. This driver only handles the ethernet
+ interface exposed by the modem firmware. To establish a connection
+ you will first need a userspace program that sends the right

+ likely also a DHCP client. See this thread about using the
