| Date: Dec 2015 | |
| KernelVersion: 4.4 | |
| Contact: Bjørn Mork <bjorn@mork.no> | |
| Description: | |
| Boolean. 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. | |

| 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. | |

| 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. | |

| Date: January 2021 | |
| KernelVersion: 5.12 | |
| Contact: Daniele Palmas <dnlplm@gmail.com> | |
| Description: | |
| Unsigned integer | |
| Indicates the mux id associated to the qmimux network interface | |
| during its creation. | |
| What: /sys/class/net/<iface>/qmi/pass_through | |
| Date: January 2021 | |
| KernelVersion: 5.12 | |
| Contact: Subash Abhinov Kasiviswanathan <quic_subashab@quicinc.com> | |
| Description: | |
| Boolean. Default: 'N' | |
| Set this to 'Y' to enable 'pass-through' mode, allowing packets | |
| in MAP format to be passed on to the stack. | |
| Normally the rmnet driver (CONFIG_RMNET) is then used to process | |
| and demultiplex these packets. | |
| 'Pass-through' mode can be enabled when the device is in | |
| 'raw-ip' mode only. |
