IPAddr2 puts the interface up on start and down on stop.
But its not able to detect an UP or DOWN change in status or monitor.
Therefore an "ifconfig <interface> down" from a thrird program or a
careless administrator would drop the link without pacemaker noticing!
The attached patch tries to fix that
