HP DLPI Features
• Connection Management STREAMS; DL_SUBS_BIND_REQ and
DL_SUBS_UNBIND_REQ over connection-oriented STREAMS.
• Acknowledged connectionless-mode services.
Device File Format
The following is a description of the device file formats required for
accessing the STREAMS DLPI LAN driver.
NOTE HP DLPI supports up to 100 non-clone device files. HP recommends that
device file names follow the naming convention /dev/dlpiX, where X is
the number of the device.
Header Files
There are two DLPI header files: dlpi.h and dlpi_ext.h. Both are in
/usr/include/sys. dlpi.h contains definitions for the standard DLPI
primitives. dlpi_ext.h contains definitions for the HP extended DLPI
primitives.
