dlpi_ext.h — HP-specific extensions for DLPI




<dlpi_ext.h> is the header file for HP-specific extensions to data link provider interface, DLPI 2.0 standard. The header file contains definitions for primitives, acknowledgements, ioctls and associated structures to satisfy needs of DLS users over and beyond what is provided by DLPI 2.0 standard.

The header file must be included by all DLS users (user-space and kernel-space) who intend to interact with LAN drivers through DLPI.

The manual page dlpi(7) provides an overview of HP-UX's DLPI. The header file <dlpi.h> contains DLPI requests; see dlpi(4). The <dlpi_drv.h> header file contains definitions that are required by networking device drivers to interact with DLPI; see dlpi_drv(4).


<dlpi_ext.h> was created by HP.


dlpi(4), dlpi_drv(4), dlpi(7), lan(7).
