NAME


dlpi_promiscon, dlpi_promiscoff - enable or disable DLPI promiscuous mode

SYNOPSIS


cc [ flag... ] file... -ldlpi [ library... ]
#include <libdlpi.h>

int dlpi_promiscon(dlpi_handle_t dh, uint_t level);


int dlpi_promiscoff(dlpi_handle_t dh, uint_t level);


DESCRIPTION


The dlpi_promiscon() function enables promiscuous mode on a DLPI link
instance associated with DLPI handle dh, at the specified level. After
enabling promiscuous mode, the caller will be able to receive all
messages destined for the DLPI link instance at the specified level. This
operation can be performed in any DLPI state of a handle.


The dlpi_promiscoff() function disables promiscuous mode on a DLPI link
instance associated with DLPI handle dh, at the specified level. This
operation can be performed in any DLPI state of a handle in which
promiscuous mode is enabled at the specified level.


The level modes are:

DL_PROMISC_PHYS
Promiscuous mode at the physical level


DL_PROMISC_SAP
Promiscuous mode at the SAP level


DL_PROMISC_MULTI
Promiscuous mode for all multicast addresses


RETURN VALUES


Upon success, DLPI_SUCCESS is returned. If DL_SYSERR is returned, errno
contains the specific UNIX system error value. Otherwise, a DLPI error
value defined in <sys/dlpi.h> or an error value listed in the following
section is returned.

ERRORS


DLPI_EBADMSG
Bad DLPI message


DLPI_EINHANDLE
Invalid DLPI handle


DLPI_EINVAL
