* The Samsung Kalmia based LTE USB modems have a CDC ACM port for modem control
* handled by the "option" module and an ethernet data port handled by this
* module.
*
* The stick must first be switched into modem mode by usb_modeswitch
* or similar tool. Then the modem gets sent two initialization packets by
* this module, which gives the MAC address of the device. User space can then
* connect the modem using AT commands through the ACM port and then use
* DHCP on the network interface exposed by this module. Network packets are
* sent to and from the modem in a proprietary format discovered after watching
* the behavior of the windows driver for the modem.
*
* More information about the use of the modem is available in usb_modeswitch
* forum and the project page:
