/**
 * Address Resolution Protocol (ARP)
 * Description: Once a route has been identified for an IP packet (so the
 * output interface and the IP address of the next hop station are known),
 * the MAC address of the next hop station is needed in order to send this
 * packet onto the next leg of the journey towards its destination
 * (as identified by its destination IP address). The MAC address of the next
 * hop station becomes the destination MAC address of the outgoing
 * Ethernet frame.
 * Hash table name: ARP table
 * Number of keys: Thousands
 * Key format: The pair of (Output interface, Next Hop IP address),
 *        which is typically 5 bytes for IPv4 and 17 bytes for IPv6.
 * value (data): MAC address of the next hop station (6 bytes).
