+		Set this to 'Y' to change the network device link

+
+		The netdev will change to reflect the link framing

+		frames with an ethernet header over the USB link. The

+		without any L2 header over the USB link.
+
+		Userspace is in full control of firmware configuration
+		through the delegation of the QMI protocol. Userspace
+		is responsible for coordination of driver and firmware
+		link framing mode, changing this setting to 'Y' if the
+		firmware is configured for 'raw-ip' mode.
