UMAXV 2.4 uses STREAMS networking, whereas UMAXV 2.2m used BSD-style
networking.  Under STREAMS, ARP is implemented as a module that is
pushed onto an open ethernet driver stream (see slink and /etc/strcf
for more info).

To issue IOCTLs to ARP (including SIOCSARP) you must open the appropriate
streams device (/dev/inet/arp) and then issue the IOCTL.
