1What: /sys/class/net/<iface>/qmi/raw_ip 2Date: Dec 2015 3KernelVersion: 4.4 4Contact: Bjørn Mork <bjorn@mork.no> 5Description: 6 Boolean. Default: 'N' 7 8 Set this to 'Y' to change the network device link 9 framing from '802.3' to 'raw-ip'. 10 11 The netdev will change to reflect the link framing 12 mode. The netdev is an ordinary ethernet device in 13 '802.3' mode, and the driver expects to exchange 14 frames with an ethernet header over the USB link. The 15 netdev is a headerless p-t-p device in 'raw-ip' mode, 16 and the driver expects to echange IPv4 or IPv6 packets 17 without any L2 header over the USB link. 18 19 Userspace is in full control of firmware configuration 20 through the delegation of the QMI protocol. Userspace 21 is responsible for coordination of driver and firmware 22 link framing mode, changing this setting to 'Y' if the 23 firmware is configured for 'raw-ip' mode. 24 25What: /sys/class/net/<iface>/qmi/add_mux 26Date: March 2017 27KernelVersion: 4.11 28Contact: Bjørn Mork <bjorn@mork.no> 29Description: 30 Unsigned integer. 31 32 Write a number ranging from 1 to 254 to add a qmap mux 33 based network device, supported by recent Qualcomm based 34 modems. 35 36 The network device will be called qmimux. 37 38 Userspace is in charge of managing the qmux network device 39 activation and data stream setup on the modem side by 40 using the proper QMI protocol requests. 41 42What: /sys/class/net/<iface>/qmi/del_mux 43Date: March 2017 44KernelVersion: 4.11 45Contact: Bjørn Mork <bjorn@mork.no> 46Description: 47 Unsigned integer. 48 49 Write a number ranging from 1 to 254 to delete a previously 50 created qmap mux based network device. 51 52What: /sys/class/net/<qmimux iface>/qmap/mux_id 53Date: January 2021 54KernelVersion: 5.12 55Contact: Daniele Palmas <dnlplm@gmail.com> 56Description: 57 Unsigned integer 58 59 Indicates the mux id associated to the qmimux network interface 60 during its creation. 61 62What: /sys/class/net/<iface>/qmi/pass_through 63Date: January 2021 64KernelVersion: 5.12 65Contact: Subash Abhinov Kasiviswanathan <quic_subashab@quicinc.com> 66Description: 67 Boolean. Default: 'N' 68 69 Set this to 'Y' to enable 'pass-through' mode, allowing packets 70 in MAP format to be passed on to the stack. 71 72 Normally the rmnet driver (CONFIG_RMNET) is then used to process 73 and demultiplex these packets. 74 75 'Pass-through' mode can be enabled when the device is in 76 'raw-ip' mode only. 77
