There are apparently a few of them depending on what mode the modem is in. Two possible theories: a) newer devices, especially Sierra ones, sometimes implement multiple QMI/Ethernet interfaces, but only some of those actually work for data. That could be what you're hitting here. We'd need the VID/PID to figure this out though. b) On "9x15" devices, the Netgear GobiNet driver uses the WDA service's Set Data Format call instead of the CTL service. Not sure if that makes a difference here or not, but maybe new devices expect the WDA mechanism instead, and so the data format is not getting switched to Ethernet? (Also it's cute that they grabbed Bjorn's header fixup workaround and added it to the GobiNet driver...) Bjorn: I see that the Sierra drivers expect the following layout Serial: 1199:68A2 - blacklisted: 8, 10, 11, 19, 20 1199:68C0 - blacklisted: 8, 10, 11 1199:9057 - blacklisted: 0, 1, 5, 8, 10, 11 ("Netgear AC341U IPT2 mode") Net: 1199:68A2 - 8, 10, 19 ("MDM9x15 PDNs") 1199:68C0 - 8, 10, 19 1199:9057 - 8, 10, 11 Which means that qmi_wwan is missing: 1199:68a2: 10 1199:68c0: 19 1199:9057: 10, 11 No idea whether adding these to qmi_wwan would be useful or not, you've done more work than I with these devices, and I'm not sure where we landed on whether or not to expose the non-functional QMI interfaces through qmi_wwan.
