RFC 826 address resolution protocol.
ARP is used to map IP addresses to hardware addresses. Each network interface of Nut/Net keeps its own mapping table.
When an IP packet has to be sent out, IP needs the hardware address to pass it to the Ethernet layer. If the mapping is not in the ARP cache, an Ethernet broadcast packet is sent to the local network requesting the physical hardware address for the given IP address.
Add functions to manually add or remove ARP entries.
Add function to query ARP tables.
