Though, in my case, I'm not actually just prepending a header. I'm doing some more substantial transformations of a packet. And this needs to work with v4 too. So I'm not sure implementing a v6 spec will help with things. I need to identify the right mechanism inside the kernel to assist with this, like, say, a member in sk_buff.
