rest_router: Fix ARP THA in reply message
Currently, rest_router sends ARP reply messages composing own MAC
address in Target MAC Address, and both Sender/Target MAC address
are MAC address of rest_router.
So, with this reply messages, Wireshark will report "Duplicate IP
address detected".
This patch fixes this problem.
This problem was reported by China Shenzhen TICOMM Information
Technology Co. Ltd.
