Enumerator
IP6_FIB_TABLE_FWDING	This table stores the routes that are used to forward traffic. The key is the prefix, the result the adjacency to forward on.
IP6_FIB_TABLE_NON_FWDING	The table that stores ALL routes learned by the DP. Some of these routes may not be ready to install in forwarding at a given time. The key in this table is the prefix, the result is the fib_entry_t
