Nothing freely available. Many commercial companies have done such things. Why
limit the general community by force-feeding a really fast packet generator
into the mainstream by squashing other ideas in their infancy? Anyone who

It's not faster than "wedging" into the if_input()s. It simply can't be. Your
getting packets at interrupt time as soon as their processed and you there's
no network stack involved, and your able to receive and transmit without a
process switch. At worst it's the same, without the extra plumbin

Frankly I'm baffled by netmap. You can easily write a loadable kernel module
that moves packets from 1 interface to another and hook in the firewall; why
would you want to bring them up into user space? It's 1000s of lines of
unnecessary code.

Clarifying things for the sake of documentation:
To use the host stack, append a ^ character after the name of the interface
you want to use. (Info from netmap(4) shipped with FreeBSD 10.1 RELEASE.)
Examples:
"kipfw em0" does nothing useful.
"kipfw netmap:em0" disconnects the NIC from the usual
