* fib: Added the ``rib_ext_sz`` field to ``rte_fib_conf`` and ``rte_fib6_conf``
so that user can specify the size of the RIB extension inside the FIB.
+* ip_frag: All macros updated to have ``RTE_IP_FRAG_`` prefix. Obsolete
+ macros are kept for compatibility. DPDK components updated to use new names.
+ Experimental function ``rte_frag_table_del_expired_entries`` was renamed to
+ ``rte_ip_frag_table_del_expired_entries`` to comply with other public
