You can't patch the Berkeley Packet Filter into Linux.  Linux kernel doesn't
support it.

and...

Despite a cacophonous chorus of replies directing you to the right tool for
the job, you insist on sticking with Linux.

If you want to use the wrong tool for the job, by all means, use
ipset/iptables - have a great time with it.  When it doesn't
give you the performance you want, then you will probably go buy something
else.

I don't care how you pretty up iptables and it's predecessor, ipchains, it's
still a black eye on Linux comparatively speaking.

Berkeley invented TCP/IP, the Berkeley TCP/IP stack is implemented on just
about every platform/OS combination there is.

Berkeley *is* networking.  And yes, the community around BSD are assholes,
but they are semi-entitled.  Their shit is way
better documented than just about anything else in Open Source, including
most things Linux.
