Lowering time between ARP probes might be a simpler solution but it has disadvantages
1. Frequent ARP probes (few seconds gap) might be disturbing during 
normal operation and I don't know if network managers would be happy to change it.
2. The time between probes has minimum value which might not be small enough to those
who want fast recovery.

I am resending the patch with a bug fix I found plus better change log
in case you consider to apply it (I hope so)
