Synopsis

#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.
