-/****************************************************************************
- * Name: arp_update
- *
- * Description:
- *   Add the IP/HW address mapping to the ARP table -OR- change the IP
- *   address of an existing association.
- *
- *   NOTE: This is an internal interface withint the networking layer and
- *   should not be used by application software.  This prototype is here
- *   because there is already a violation of this structureing:  The
- *   apps/netutils/dhcpd logic currently calls arp_update() directly.  That
- *   is bad and needs to be replace with some ioctl interface perhaps hidden
- *   somewhere in apps/netutils/netlib.
- *
- * Input parameters:
- *   pipaddr - Refers to an IP address uint16_t[2] in network order
- *   ethaddr - Refers to a HW address uint8_t[IFHWADDRLEN]
- *
- * Assumptions
- *   Interrupts are disabled to assure exclusive access to the ARP table.
- *
