+ipfrag_max_dist - INTEGER
+	ipfrag_max_dist is a non-negative integer value which defines the 
+	maximum "disorder" which is allowed among fragments which share a 
+	common IP source address. Note that reordering of packets is 
+	not unusual, but if a large number of fragments arrive from a source 
+	IP address while a particular fragment queue remains incomplete, it 
+	probably indicates that one or more fragments belonging to that queue 
+	have been lost. When ipfrag_max_dist is positive, an additional check 
+	is done on fragments before they are added to a reassembly queue - if 
+	ipfrag_max_dist (or more) fragments have arrived from a particular IP 
+	address between additions to any IP fragment queue using that source 
+	address, it's presumed that one or more fragments in the queue are 
+	lost. The existing fragment queue will be dropped, and a new one 
+	started. An ipfrag_max_dist value of zero disables this check.
+
+	Using a very small value, e.g. 1 or 2, for ipfrag_max_dist can
+	result in unnecessarily dropping fragment queues when normal
+	reordering of packets occurs, which could lead to poor application 
+	performance. Using a very large value, e.g. 50000, increases the 
+	likelihood of incorrectly reassembling IP fragments that originate 
+	from different IP datagrams, which could result in data corruption.
