48.bit: Ethernet address of destination
48.bit: Ethernet address of sender
16.bit: Protocol type = ether_type$ADDRESS_RESOLUTION
Ethernet packet data:
16.bit: (ar$hrd) Hardware address space (e.g., Ethernet,
Packet Radio Net.)
16.bit: (ar$pro) Protocol address space. For Ethernet
hardware, this is from the set of type
fields ether_typ$
8.bit: (ar$hln) byte length of each hardware address
8.bit: (ar$pln) byte length of each protocol address
16.bit: (ar$op) opcode (ares_op$REQUEST | ares_op$REPLY)
nbytes: (ar$sha) Hardware address of sender of this
packet, n from the ar$hln field.
mbytes: (ar$spa) Protocol address of sender of this
packet, m from the ar$pln field.
nbytes: (ar$tha) Hardware address of target of this
packet (if known).
mbytes: (ar$tpa) Protocol address of target.
