• Inform HP-DLPI each time the MAC address changes. This is required for LAN commands to display the current MAC address. • Support specific ioctls, standard DLPI primitives, and specific HP extensions of DLPI primitives. This ensures the driver will w ork with standard HP-UX LAN commands and SMH. For information on writing a Nativ e driver , s[...]
