The point of this is so that I can play around with the packets construction however I please to try out a few things. I have successfully implemented one version of my code on FreeBSD. However this is done directly inside the kernel and I would like to attempt a Linux implementation as a module for greater flexibility. I have only just started looking into this and was wondering if anyone could give me any pointers on how I might be able to achieve this. I am fairly new in the world of Linux kernel hacking with most of my previous experience being working with the FreeBSD kernel. Any pointers will be much appreciated. Cheers Matt
