Dell wireless modem DW5560

Kernel drivers
To make it work, the following kernel drivers (as of linux-4.9) need to be activated:


 * USB Modem (CDC ACM) support ( CONFIG_USB_ACM )
 * USB Wireless Device Management support ( CONFIG_USB_WDM )
 * USB MBIM support ( CONFIG_USB_NET_CDC_MBIM )

For rfkill, the Dell Laptop Extras ( CONFIG_DELL_LAPTOP ) option might need to be enabled as well.
