The problem is, I suspect, that, on Linux, SIOCGIFCONF only finds
interfaces that have IP addresses, and that's what Ethereal uses to get
the list of interfaces.

The "pcap_findalldevs()" routine in recent libpcaps will, on Linux, also
look in "/proc/net/dev" for interfaces.  At some point we should
probably arrange that Ethereal use "pcap_findalldevs()" if present.
