6*40dd0d94SBjørn Mork		Boolean.  Default: 'N'
7*40dd0d94SBjørn Mork
8*40dd0d94SBjørn Mork		Set this to 'Y' to change the network device link
9*40dd0d94SBjørn Mork		framing from '802.3' to 'raw-ip'.
10*40dd0d94SBjørn Mork
11*40dd0d94SBjørn Mork		The netdev will change to reflect the link framing
12*40dd0d94SBjørn Mork		mode.  The netdev is an ordinary ethernet device in
13*40dd0d94SBjørn Mork		'802.3' mode, and the driver expects to exchange
14*40dd0d94SBjørn Mork		frames with an ethernet header over the USB link. The
15*40dd0d94SBjørn Mork		netdev is a headerless p-t-p device in 'raw-ip' mode,
16*40dd0d94SBjørn Mork		and the driver expects to echange IPv4 or IPv6 packets
17*40dd0d94SBjørn Mork		without any L2 header over the USB link.
18*40dd0d94SBjørn Mork
19*40dd0d94SBjørn Mork		Userspace is in full control of firmware configuration
20*40dd0d94SBjørn Mork		through the delegation of the QMI protocol. Userspace
21*40dd0d94SBjørn Mork		is responsible for coordination of driver and firmware
22*40dd0d94SBjørn Mork		link framing mode, changing this setting to 'Y' if the
23*40dd0d94SBjørn Mork		firmware is configured for 'raw-ip' mode.
