If you want to plumb things together, do you need libpcap?

Why would I use libpcap for that?

But wouldn't I create a netmap pipe using something other than libpcap, and only use libpcap if I want to watch the 
traffic on that pipe?

I.e., what would be lost if, for example, libpcap only supported capturing on existing netmap devices, and didn't 
support creating new ones on the fly?
