 * This may not work with all kernels. If it does not work please enter a bug at bugs.gentoo.org
 * This only patches the current kernel source code. (/usr/src/linux)
 * Its up to you to recompile the kernel with the l7 options

 * You will also need to emerge iptables with the "extensions" or
 * "l7filter" USE flag (depend which version of iptables you emerge)
