Hi, Alain.

I think the main differences are in the design: NPF was designed from
the ground up to scale well on a multi-core system, and it was designed
to use byte-code processing for protocol independence and flexibility.

You might choose NPF because of the differences noted above.  You also
might choose NPF if you're running NetBSD because it's the "NetBSD
packet filter."

Not that I know of.

Yes [1][2][3].
