- *
- * HISTORY
- * 09-Apr-90 Bradley Taylor (btaylor) at NeXT, Inc.
- * Move Ethernet definitions to <net/etherdefs.h>. Leave arp stuff here.
- *
- * 20-Oct-87 Peter King (king) at NeXT, Inc.
- * SUN_RPC: Add definition for ether_addr. Add RARP support.
- *
- * 25-Jan-86 Avadis Tevanian (avie) at Carnegie-Mellon University
- * Upgraded to 4.3.
- *
- * 15-Aug@ Mike Accetta (mja) at Carnegie-Mellon University
- * CS_INET: added ac_if field to arptab definition to allow
- * multiple interfaces to co-exist.
- * [V1(1)]
