They have cdc-acm serial ports and firmware has implemented AT commands for (de)activating the pseudo Ethernet and getting IP + DNS values etc. Actually applying this patch will provide little in terms of operation except to make the interface name wwan%d unstead of usb%d and to flag the interface such that Network Manager does not try to bring it up via DHCP as soon as it appears, like it would with a fixed Ethernet interface. Good tip about the 'unexpected notification 01' I'll look out for that!
