No we haven't put struct socket in the leafs (result node) yet we just kept
dst entries and some stateful flow variables that we used for active GC
and flow logging so far. So 128 bit flow version of the dst hash. It would
have taken a lot a of more work and we wanted to get this paper out. Also
ip_route_input is not the place have the lookup if we with unified include
ip6. So we focused on designing and building the lookup core.
Cheers.
