Libpcap may now say "The interface disappeared" if it did.
A recent change to libpcap means that the error message if an interface disappears (e.g., removing a hot-pluggable device, or shutting down a PPP connection that was dynamically set up) is "The interface disappeared" rather than "The interface went down" - on FreeBSD, DragonFly BSD, OpenBSD, and Darwin-based OSes, capturing continues with no error if the interface is configured down, but either ENXIO or EIO (depending on the OS) is delivered if the interface disappears. Treat that error as another one to show the user without the "report this to the Wireshark developers" note.
