libpcap on OS X

Earlier I wrote about a problem with libpcap on OS X. This is the call in the code that breaks the wireless connection.

/* ask pcap to find a valid device for use to sniff on */
dev = pcap_lookupdev(errbuf);

but replace it with this (en1 is my wireless interface)

dev="en1";

and then use dev in other libpcap functions and it works fine.
