fib_trie: resize rework
Here is rework and cleanup of the resize function. Some bugs we had. We were using ->parent when we should use node_parent(). Also we used ->parent which is not assigned by inflate in inflate loop. Also a fix to set thresholds to power 2 to fit halve and double strategy. max_resize is renamed to max_work which better indicates it's function. Reaching max_work is not an error, so warning is removed. max_work only limits amount of work done per resize. (limits CPU-usage, outstanding memory etc). The clean-up makes it relatively easy to add fixed sized root-nodes if we would like to decrease the memory pressure on routers with large routing tables and dynamic routing. If we'll need that... Its been tested with 280k routes. Work done together with Robert Olsson. Signed-off-by: Jens Låås <jens.laas@its.uu.se> Signed-off-by: Robert Olsson <robert.olsson@its.uu.se> Signed-off-by: David S.
