FreeBSD network optimization project

[Vitalii Duk]

Luigi, your project is really interesting, you've done a great job!
I will try to test ipfw and dummynet with netmap in my netork.
But there is still a problem with NAT and libalias. I havent tried new
SMP-friendly pf NAT, maybe it will give a good perfomance. But it will be
also great to have something working with ipfw.

I think in my previous list I forget to note about two more problems:
1. Not full support of LACP in FreeBSD (for example it's not possible to
set priority, hash algorithm and mode(active/passive)).
2. No support of *RFC 3069 (IP unnumbered/SuperVLAN).*
