• 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 work with standard HP-UX LAN commands and
SMH.
For information on writing a Native driver, see the HP-UX 11i v3 Driver Development Guide. Key
native-to-native driver migration issues are noted in the next section of this document.
Figure 1-2 shows the native driver architecture.
