Hi. If you haven't read the "The Linux Kernel" guide networking sections, they might give you a hint. They are NOT IPv6 specific, but I assume that the implementation is not so different from the IPv4. The data structures will differ but I think that operations are quite similar... "The Linux Kernel" guide is located on the LDP homepages. [ http://sunsite.unc.edu/mdw/ ] Hope this helps.
