The "all" in "pcap_findalldevs" is there for a reason; the job of  
pcap_findalldevs() is to find *all* of the devices that could be  
opened with pcap_open_live().  As different applications might have  
different requirements, it's not the job of pcap_findalldevs() to  
filter the list of devices for the convenience of particular  
applications, so it'll continue to list the GenericDialupAdapter on  
Windows, just as it continues to list the "any" adapter on Linux, etc..

The application writer has to determine what the criterion is for  
determining what adapters should be shown.  There's no guarantee that  
the real criterion corresponds to, for example, "the adapter has an IP  
address".  What are the real criteria that the programs being  
discussed here have?
