+Subject: [PATCH] fib_trie: Use empty_children instead of counting empty nodes
+ in stats collection
+
+It doesn't make much sense to count the pointers ourselves when
+empty_children already has a count for the number of NULL pointers stored
+in the tnode. As such save ourselves the cycles and just use
+empty_children.
