| What: /sys/class/net/<iface>/qmi/raw_ip |
| 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. |

| 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. |

| 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. |
