Stephen Hemminger d5ce8a0e97 [IPV4] fib_trie: avoid rescan on dump 
This converts dumping (and flushing) of large route tables form O(N^2)
to O(N). If the route dump took multiple pages then the dump routine
gets called again. The old code kept track of location by counter, the
new code instead uses the last key.

This is a really big win ( 0.3 sec vs 12 sec) for big route tables.

One side effect is that if the table changes during the dump, then the
last key will not be found, and we will return -EBUSY.
