Hi

I read bpf(4) man page and have one question about BPF.
Suppose I open one of free BPF devices /dev/bpf??. I can dup(2)
descriptor of opened BPF device and get so called shared interface.

Can I setup different filters on each descriptor for opened BPF device?
If I can do it, how can I do the same with pcap(3) library?

Thanks for answers.
