You can change the polling interval with the miimon option, but
I'm not sure how precise you can get, it does take some time for
the system to register a link failure, if that is infact what
causes the network to fail. Another failure mode is a layer 2
failure which can detected in some cases using the arp monitor.
I think rather than trying to achieve zero loss on the network
with regards to failures you should tune the cluster to be
more tolerant and not raise a fit if the network is down for
a second or two.
