[ Upstream commit67d1a8956d] Set FLAG_WWAN instead of FLAG_ETHERNET for RNDIS interfaces on Mobile Broadband Modems, as opposed to regular Ethernet adapters. Otherwise NetworkManager gets confused, misjudges the device type, and wouldn't know it should connect a modem to get the device to work. What would be the result depends on ModemManager version -- older ModemManager would end up disconnecting a device after an unsuccessful probe attempt (if it connected without needing to unlock a SIM), while a newer one might spawn a separate PPP connection over a tty interface instead, resulting in a general confusion and no end of chaos. The only way to get this work reliably is to fix the device type and have good enough version ModemManager (or equivalent).
