Detailed Description

Class ARP Packet for simulation.

This class defines an ARP packet as a stream of 'AxisArp' data chunks. Such an ARP packet consists of a double-ended queue that is used to accumulate all these data chunks. For the 10GbE MAC, the ARP chunks are 64 bits wide. ARP chunks are extracted from the Ethernet frame by the IPRX core and are transmitted to the ARP core.
