This patch fixes relayd not adding a host on an ARP request for the local IP address. When relayd is launched using the -L option, it was not adding the necessary host routes when it receives an ARP request for the local IP address.
This issue makes a host not able to connect to the device running relayd until there is ARP traffic involving a third host.
