SunOS 5.5 Devices eepro(7D)

The DL_PROMISCON_REQ andDL_PROMISCOFF_REQ primitives with the

DL_PROMISC_PHYS ﬂag set in the dl_level ﬁeld enables/disablesreception of all “prom-

iscuous mode” frames on the media including frames generated by the local host.

When used with the DL_PROMISC_SAP ﬂag set, this enables/disablesreception of all sap

(Ethernet type) values. When used with the DL_PROMISC_MULTI ﬂag set, this

enables/disables reception of all multicast group addresses. The effect of each is always

on a per-stream basis and independent of the other sap and physical level conﬁgurations

on the stream or other streams.

The DL_PHYS_ADDR_REQ primitive returns the 6-byte Ethernet address currently associ-

ated (attached) to the stream in theDL_PHYS_ADDR_ACK primitive. This primitive is

valid only in states following a successful DL_ATTACH_REQ.

The DL_SET_PHYS_ADDR_REQ primitive changesthe 6-byte Ethernet address currently

associated (attached) to this stream. The credentials of the process which originally

opened this stream must be superuser or anEPERM error is returned in the

DL_ERROR_ACK. This primitive is destructive in that it affects all other current and

future streams attached to this device. An M_ERROR message is sent up all other streams

attached to this device when this primitive is successful on this stream. Once changed, all

streams subsequently opened and attached to this device will obtain this new physical

address. The new physical address will remain in effect until this primitive is used to

change the physical address again or the system is rebooted, whichever comes ﬁrst.

IOCTLS The following ioctl request is supported:

TDR_TEST Performs the time domain reﬂectometry test. This test checks for net-

work faults. The argument should be NULL. The values returned are

interpreted as follows:

0x8000 No network fault was detected. The transmission link

that is connected to the network controller is function-

ing properly.

0x2000 The transmission line connected to the hardware con-

troller is open (i.e. The linehas not been properly ter-

minated).

0x1000 A short exists on the transmission line.

This ioctl request is deﬁned in <sys/eepro.h>.

CONFIGURATION The eepro.conf ﬁle supports the following options:

intr Speciﬁes theIRQ level for the board (see sysbus(4)).

Auto-detect of the media type is supported and the board need not be explicitly

conﬁgured for which media connector it is using. It is important to ensure that there are

no conﬂicts between the board’s I/O port or IRQ level and other hardware installed in the

system.
