I need run a sniffer/libpcap program in freebsd-7.2-amd64 which compiled
for freebsd-6.2-i386. it coredumped in pcap_setnonblock().seems 7.2-amd64's
ioctl() does not recognize the 6.2-i386 bpf ioctl() request. BIOCGDLTLIST
request failed.
maybe BIOCSRTIMEOUT cause program coredumped.
char errstr[1024];
pcap_t *pd1;
pd1 = pcap_open_live("em0", 8192, 1, 1000, errstr);
pcap_setnonblock(pd1, 1, errstr);
