Default: 'N' + + Set this to 'Y' to change the network device link + framing from '802.3' to 'raw-ip'. + + The netdev will change to reflect the link framing + mode. The netdev is an ordinary ethernet device in + '802.3' mode, and the driver expects to exchange + frames with an ethernet header over the USB link. The + netdev is a headerless p-t-p device in 'raw-ip' mode, + and the driver expects to echange IPv4 or IPv6 packets + 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. |
