struct { ... } ip_adjacency_t_::glean |
IP_LOOKUP_NEXT_GLEAN.
Glean the address to ARP for from the packet's destination. Technically these aren't adjacencies, i.e. they are not a representation of a peer. One day we might untangle this coupling and use a new Glean DPO.

IP_LOOKUP_NEXT_MIDCHAIN.
A nbr adj that is also recursive. Think tunnels. A nbr adj can transition to be of type MIDCHAIN so be sure to leave the two structs with the next_hop fields aligned.
