It uses a garbage collector that sets: 1) a minimum number of arp entries (gc_thresh1) below which the garbage collector will not run 2) a soft maximum number of entries (gc_thresh2) above which the garbage collector will allow the arp table size to cross for a short period of time 3) a maximum number of hard entries (gc_thresh3) above which the garbage collector will forcibly remove entries to make room for new ones (using a least recently used algorithm IIRC).
