ARPUPDATE introduced
The ARPUPDATE option has been introduced. It defaults to 'yes'.
By setting the ARPUPDATE to 'no', administrator can disable
updating neighbouring computers with ARP information about current
NIC. This is especially needed when using LVS Load Balancing with
Direct routing enabled.
