void ip64_arp_init ( void )

Initialize the ARP module.

References arp_table, i, ipaddr, and UIP_ARPTAB_SIZE.

void ip64_arp_timer ( void )

Periodic ARP processing function.

This function performs periodic timer processing in the ARP module and should be called at regular intervals. The recommended interval is 10 seconds between the calls.
