AFAIK reset_resume doesn't really work for 3G/LTE modems. Too much state to restore both in firmware and network, with no well defined protocol to restore it. The only reason for having reset_resume in the modem drivers is that quite a few modems have an SD reader. We need to support persist for the usb-storage function, even if the modem functions fail. There is no reason to mess up the file system too. Bjørn
