May I ask why and how?

Well, what if the link is up but there's an upstream problem? I've
always liked how ocf:pacemaker:ping actually monitors connectivity to an
upstream IP, which covers both immediate link failure and upstream
problems. Similar to how in active/backup bonding, you can fail over
based on the status of an ARP request, rather than MII link status.

Your thoughts?
