Right now almost all USB networking drivers make the device disappear immediately ... certainly the ones that have made sure they handle the USB disconnect processing correctly (no more I/O to that device!) tend to do that, by calling unregister_netdev(). ... which would let Linux implement a NotPresent(ifname) test just by seeing if it's registered, unless that RFC demands some more abstruse meaning. (I've not read it lately.) |
