* Agent sends a arp request to VM, and the response gets trapped
  to agent if a flag is set in route to trap arp response.
  In race condition agent may send a ARP request, which VM would
  respond back, but the packet may not be trapped since ksync
  may not have programmed to trap the packet. Now agent retries
  for ARP request
