Default: 'N' 7*4882a593Smuzhiyun 8*4882a593Smuzhiyun Set this to 'Y' to change the network device link 9*4882a593Smuzhiyun framing from '802.3' to 'raw-ip'. 10*4882a593Smuzhiyun 11*4882a593Smuzhiyun The netdev will change to reflect the link framing 12*4882a593Smuzhiyun mode. The netdev is an ordinary ethernet device in 13*4882a593Smuzhiyun '802.3' mode, and the driver expects to exchange 14*4882a593Smuzhiyun frames with an ethernet header over the USB link. The 15*4882a593Smuzhiyun netdev is a headerless p-t-p device in 'raw-ip' mode, 16*4882a593Smuzhiyun and the driver expects to echange IPv4 or IPv6 packets 17*4882a593Smuzhiyun without any L2 header over the USB link. 18*4882a593Smuzhiyun 19*4882a593Smuzhiyun Userspace is in full control of firmware configuration 20*4882a593Smuzhiyun through the delegation of the QMI protocol. Userspace 21*4882a593Smuzhiyun is responsible for coordination of driver and firmware 22*4882a593Smuzhiyun link framing mode, changing this setting to 'Y' if the 23*4882a593Smuzhiyun firmware is configured for 'raw-ip' mode. 24*4882a593Smuzhiyun 25*4882a593SmuzhiyunWhat: /sys/class/net/<iface>/qmi/add_mux 26*4882a593SmuzhiyunDate: March 2017 27*4882a593SmuzhiyunKernelVersion: 4.11 28*4882a593SmuzhiyunContact: Bjørn Mork <bjorn@mork.no> 29*4882a593SmuzhiyunDescription: 30*4882a593Smuzhiyun Unsigned integer. 31*4882a593Smuzhiyun 32*4882a593Smuzhiyun Write a number ranging from 1 to 254 to add a qmap mux 33*4882a593Smuzhiyun based network device, supported by recent Qualcomm based 34*4882a593Smuzhiyun modems. 35*4882a593Smuzhiyun 36*4882a593Smuzhiyun The network device will be called qmimux. 37*4882a593Smuzhiyun 38*4882a593Smuzhiyun Userspace is in charge of managing the qmux network device 39*4882a593Smuzhiyun activation and data stream setup on the modem side by 40*4882a593Smuzhiyun using the proper QMI protocol requests. 41*4882a593Smuzhiyun 42*4882a593SmuzhiyunWhat: /sys/class/net/<iface>/qmi/del_mux 43*4882a593SmuzhiyunDate: March 2017 44*4882a593SmuzhiyunKernelVersion: 4.11 45*4882a593SmuzhiyunContact: Bjørn Mork <bjorn@mork.no> 46*4882a593SmuzhiyunDescription: 47*4882a593Smuzhiyun Unsigned integer. 48*4882a593Smuzhiyun 49*4882a593Smuzhiyun Write a number ranging from 1 to 254 to delete a previously 50*4882a593Smuzhiyun created qmap mux based network device. 51
