This variable defines the average number of entries per hash line, when rehashing is finished. A value of 2 means e.g., that, after rehashing finished, the number of entries in the hash table is at most twice the number of hash anchors (i.e. number of hash anchors increased accordingly). If the value is configured to be greater or equal to ipsecTuneAutoRehashMaxEntriesPerLine, automatic rehashing is de facto disabled, automatic decreasing of hash anchors isn't performed. Default value is 2.
