-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.
