NAME
       dlb, dlpi - STREAMS pseudodevice driver for bridging BSD Drivers to STREAMS

SYNOPSIS
       #include <sys/dlpihdr.h>
       #include <fcntl.h>

       fd = open ("/dev/streams/dlb", O_RDWR, 0);

DESCRIPTION
       The  dlb  STREAMS  pseudodevice driver provides a communication path between BSD-style device drivers and STREAMS protocol stacks.  The dlb
       STREAMS pseudodevice driver is the Stream end in a Stream that communicates with BSD-based device drivers.

       When the /dev/streams/dlb character device is open, a Stream is constructed between a Stream head and the dlb pseudodevice  driver.   After
       the  Stream  that  is intended to communicate with the BSD-based driver or drivers is created, the protocol module or modules can be pushed
       onto it.

       Tru64 UNIX supports a subset of the Data Link Provider Interface (DLPI) connectionless mode of communication.  The attach DLPI primitive is
       required to associate a particular physical point of attachment (PPA) with a Stream in Tru64 UNIX's implementation of the style 2 provider.

       On  the write side, the dlb pseudodevice driver translates connectionless style 2 DLPI messages to the appropriate BSD ifnet interface mes-
       sages.  On the read side, the user-bound Service Access Point (SAP) messages received from a selected PPA over BSD based driver or  drivers
       are sent upstream.
