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. + +What: /sys/class/net/<iface>/qmi/add_mux +Date: March 2017 +KernelVersion: 4.11 +Contact: Bjørn Mork <bjorn@mork.no> +Description: + Unsigned integer. + + Write a number ranging from 1 to 254 to add a qmap mux + based network device, supported by recent Qualcomm based + modems. + + The network device will be called qmimux. + + Userspace is in charge of managing the qmux network device + activation and data stream setup on the modem side by + using the proper QMI protocol requests. + +What: /sys/class/net/<iface>/qmi/del_mux +Date: March 2017 +KernelVersion: 4.11 +Contact: Bjørn Mork <bjorn@mork.no> +Description: + Unsigned integer. + + Write a number ranging from 1 to 254 to delete a previously + created qmap mux based network device. |
