All rights reserved. .TH dlpi_promiscon 3DLPI "25 Nov 2014" "Oracle Solaris 11.4" "Data Link Provider Interface Library Functions" .SH NAME dlpi_promiscon, dlpi_promiscoff \- enable or disable DLPI promiscuous mode .SH SYNOPSIS .LP .nf \fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-ldlpi\fR [ \fIlibrary\fR... ] #include <libdlpi.h> \fBint\fR \fBdlpi_promiscon\fR(\fBdlpi_handle_t\fR \fIdh\fR, \fBuint_t\fR \fIlevel\fR); .fi .LP .nf \fBint\fR \fBdlpi_promiscoff\fR(\fBdlpi_handle_t\fR \fIdh\fR, \fBuint_t\fR \fIlevel\fR); .fi .SH DESCRIPTION .sp .LP The \fBdlpi_promiscon()\fR function enables promiscuous mode on a \fBDLPI\fR link instance associated with \fBDLPI\fR handle \fIdh\fR, at the specified \fIlevel\fR. After enabling promiscuous mode, the caller will be able to receive all messages destined for the \fBDLPI\fR link instance at the specified \fIlevel\fR. This operation can be performed in any \fBDLPI\fR state of a handle. .sp .LP The \fBdlpi_promiscoff()\fR function disables promiscuous mode on a \fBDLPI\fR link instance associated with \fBDLPI\fR handle \fIdh\fR, at the specified level. This operation can be performed in any \fBDLPI\fR state of a handle in which promiscuous mode is enabled at the specified \fIlevel\fR. .sp .LP The \fIlevel\fR modes are: .sp .ne 2 .mk .na \fB\fBDL_PROMISC_PHYS\fR\fR .ad .RS 20n .rt Promiscuous mode at the physical level .RE .sp .ne 2 .mk .na \fB\fBDL_PROMISC_SAP\fR\fR .ad .RS 20n .rt Promiscuous mode at the \fBSAP\fR level .RE .sp .ne 2 .mk .na \fB\fBDL_PROMISC_MULTI\fR\fR .ad .RS 20n .rt Promiscuous mode for all multicast addresses .RE .sp .LP The level modifier (OR'd with \fIlevel\fR) is: .sp .ne 2 .mk .na \fB\fBDL_PROMISC_NOLOOP\fR\fR .ad .RS 21n .rt Do not loopback messages to the client. .sp As per the DLPI standard, any message sent over \fB_dh_\fR is looped back and received if it matches the level specified above. To prevent this, \fBDL_PROMISC_NOLOOP\fR may be OR'd into the level when calling \fBdlpi_promiscon()\fR. This behavior remains in effect until the promiscuous mode is disabled through \fBdlpi_promiscoff()\fR. .RE .SH RETURN VALUES .sp .LP Upon success, \fBDLPI_SUCCESS\fR is returned. If \fBDL_SYSERR\fR is returned, \fBerrno\fR contains the specific UNIX system error value. Otherwise, a \fBDLPI\fR error value defined in \fB<sys/dlpi.h>\fR or an error value listed in the following section is returned. .SH ERRORS .sp .ne 2 .mk .na \fB\fBDLPI_EBADMSG\fR\fR .ad .RS 18n .rt Bad DLPI message .RE .sp .ne 2 .mk .na \fB\fBDLPI_EINHANDLE\fR\fR .ad .RS 18n .rt Invalid \fBDLPI\fR handle .RE .sp .ne 2 .mk .na \fB\fBDLPI_EINVAL\fR\fR .ad .RS 18n .rt Invalid argument .RE .sp .ne 2 .mk .na \fB\fBDLPI_ETIMEDOUT\fR\fR .ad .RS 18n .rt \fBDLPI\fR operation timed out .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for description of the following attributes: .sp .TS tab( ) box; lw(2.75i) |lw(2.75i) lw(2.75i) |lw(2.75i) .
