SunOS 5.5 Devices smc(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 that originally opened

this stream must be superuser or EPERM is returned in the DL_ERROR_ACK. This primi-

tive 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 on this stream is successful. Once changed, all streams subsequently

opened and attached to this device will obtain this new physical address. Once changed,

the physical address will remain in effect until this primitive is used to change the physi-

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

CONFIGURATION The smc.conf ﬁle supports the following options:

intr Speciﬁes theIRQ (Interrupt Request) level for the board.

reg Speciﬁes the sharedRAM the board is jumpered for.

It is important to ensure that there are no conﬂicts for the board’s I/O port, shared RAM,

or IRQ level.
