I'm building a FreeBSD router based on a small, Intel Atom-based 
board and am trying to decide whether or not to configure the 
kernel for polling. What's the current state of interface polling 
in FreeBSD? Is it worth doing with a single CPU, or will it 
actually increase system overhead? What "HZ" settings are recommended?
