It looks to me that they started NPF from scratch.
Wait... What? Yet another packet filter in the BSD world? I understand the needs, but it might have been easier to work on the grounds of another packet filter (pf anyone?).
Well, if some guy wants to write a packet filter, I say, let him write a packet filter! Personally I think it sounds interesting; I have never used PF on a SMP machine (actually, I've pulled processors from OpenBSD / PF machines to save power) but the PF docs are pretty up front about SMP often not being helpful. If somebody's enthusiastic about trying a different way, that's great.
