NAME

       ifnet - STREAMS ifnet module for bridging STREAMS device drivers  to sockets

SYNOPSIS

       #include <sys/stropts.h> #define  PIFNET_IOCTL_UNIT 1236

       int ioctl(
	       type fildes,
	       type command,
	       type arg );

       int fildes, command;

DESCRIPTION

       ifnet  is  a  STREAMS-based  module that provides a bridge between STREAMS-based device drivers written to the Data Link Provider Interface
       (DLPI) and sockets.  By using ifnet, STREAMS-based DLPI device drivers can work with TCP/IP, or any other networking protocols, implemented
       using sockets.

       An  application	pushes	the  ifnet module onto a Stream opened to the device driver.  The application must then send an I_STR ioctl with a
       command of IFNET_IOCTL_UNIT to notify ifnet of the driver's unit number.  It must then send a DL_BIND_REQ downstream to bind the  appropri-
       ate protocol.

       Once  the Stream or Streams are set up, the application has no work to do but must stay around to keep the Streams alive.  This can be done
       with the pause(3) function.

EXAMPLES

       The following example illustrates how to send an I_STR ioctl with a command of IFNET_IOCTL_UNIT to notify ifnet of the driver's	unit  num-
       ber.  struct strioctl str; int unit;
	.
	.
	.  str.ic_cmd = IFNET_IOCTL_UNIT; str.ic_dp = &unit;  /* unit number of device */ ioctl(fd, I_STR, &str);
