| ...
| ... | RFC826 ARP: Eth-IPv4 and Eth-ARP on links TG-DUT1, TG-DUT2, DUT1-DUT2:
| ... | IPv4 ARP tests use 3-node topology TG - DUT1 - DUT2 - TG with one link
| ... | between the nodes. DUT1 and DUT2 are configured with IPv4 routing and
| ... | static routes. DUT ARP functionality is tested by making TG send ICMPv4
| ... | Echo Requests towards its other interface via DUT1 and DUT2.
