I actually have no intention of doing this! I'm wondering if there
already is a member in sk_buff that moonlights as my desired ttl
counter, or if there's another mechanism for avoiding routing loops. I
want to work with what's already there, rather than meddling with the
innards of important and memory sensitive structures such as sk_buff.
