SunOS 5.5 Devices iee(7D)

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 this stream or other streams.

The DL_PHYS_ADDR_REQ primitive returns the 6-octet Ethernet address currently asso-

ciated (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-octet 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 is sent up all other streams attached

to this device when this primitive on this stream is successful. 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.

CONFIGURATION The /kernel/drv/iee.conf ﬁle supports the following options:

intr Speciﬁes the IRQ level for the board.

The iee driver does not support the use of shared RAM on the board. Auto-detect of the

media type is also not supported and the board has to be explicitly conﬁgured for which

media connector it is using. It is important to ensure that there are no conﬂicts for the

board’s I/O port, shared RAM, or IRQ level.
