The FIB table index in which to find the next-hop.
The FIB index in which to perfom the next lookup.
This needs to be fixed. We should lookup the adjacencies in a separate table of adjacencies, rather than from the FIB. Two reasons I can think of:
we can only return link-type IPv4 and so not the link-type MPLS. more on this in a later commit.
The table ID should only belong to a recursive path and indicate which FIB should be used to resolve the next-hop.
