Please do. It's a change in the right direction and, as you say, it's a
prerequisite to parallelizing ipfw.

I haven't done a careful reading (comparing old/new code), but I doubt
I'd find a bug anyway :) One thing that you may want to consider is
calling ether_init_netpacket() explicitly rather than implicitly in
ether_mport(); let ether_mport() only do what its name suggests.
