FWIW rolling monitoring functions into start/stop instead of using
separate mon daemon has always been on of my big gripes with the current
incarnation of linux ha stack.

I've a nic.monitor script here that's simply

> open( IN, "ethtool $nic 2>&1 |" ) or die "Cannot run ethtool $nic: $OS_ERROR\n";

and it doesn't have to be a "resource agent" or a custom implementation
of ifdown, or anything.
