Set DMAC when eth-port has NO-ARP set
Set DMAC when eth-port has NO-ARP set

When No-ARP flag is set to eth-port, we were not setting the dmac field
in the tunnel-nh rewrite string. As a result, the tunnel packets were
getting dropped in host-os.

Modified code to set physical-interface mac as dest-mac.
