29 * See RFC 826 for protocol description. ARP packets are variable
30 * in size; the arphdr structure defines the fixed-length portion.
31 * Protocol type values are the same as those for 10 Mb/s Ethernet.
32 * It is followed by the variable-sized fields ar_sha, arp_spa,
33 * arp_tha and arp_tpa in that order, according to the lengths
34 * specified. Field names used correspond to RFC 826.
