The ip_fw code isnt in violating of the GPL because the component doesnt
contain any restrictions that violate the GPL. So when its part of the
kernel said component is under the GPL. It was left with the original
note long ago so that we could share firewall code back to the FreeBSD
people. Similarly the the cisco hdlc code in 2.1.12x is part of a GPL
total, but as a seperate work its under a much looser license.
