NAME

dlpi_drv.h - deﬁnitions of interfaces for device drivers to interact with DLPI

SYNOPSIS

/usr/include/sio/dlpi_drv.h

DESCRIPTION

The <dlpi_drv.h> header ﬁle contains deﬁnitions of structures and function prototypes that are

required by networking device drivers to interact with DLPI (data link provider interface).

The header ﬁle contains interfaces that could be used by tightly coupled and loosely coupled drivers. DLPI

serves as a sole interface to DLS users for tightly coupled drivers. Whereas, a loosely coupled driver

depends on DLPI only to provide information to userspace commands nwmgr(1M) and lanscan(1M) for

display purposes.

All loosely coupled and tightly coupled drivers must include this ﬁle.

The manuals page dlpi(7) provides an overview of HP-UX’s DLPI. The header ﬁle

<dlpi.h> contains

DLPI requests; see dlpi(4). The header ﬁle

<dlpi_ext.h> provides HP-speciﬁc extensions to DLPI 2.0

standards; see dlpi_ext(4).

WARNINGS

The interfaces provided in

<dlpi_drv.h> may change in the next HP-UX release.

The lanadmin, lanscan, and linkloop commands are deprecated. These commands will be removed

in a future HP-UX release. HP recommends the use of replacement command nwmgr(1M) to perform all

network interface-related tasks.
