nei(7D) Devices SunOS 5.5

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 nei.conf is the conﬁguration ﬁle for the nei device driver. The nei.conf ﬁle supports the

following options:

intr Speciﬁes theIRQ level for the board.

ioaddr Speciﬁes the iobase address for the board.

reg Speciﬁes the physical address and length in bytes of the device’s

memory-mapped address space. These are valid in shared

memory mode.

mode Speciﬁes the operating mode (shared memory or I/O mode) for

the device. "smmode" speciﬁes shared memory for the

NE2000plus board; any other value defaults to I/O mode. The

NE2000 board always defaults to I/O mode.

The nei driver supports the use of shared RAM only on NE2000plus boards. It is impor-

tant to ensure that there are no conﬂicts for the board’s I/O port, shared RAM,orIRQ

level. See the Solaris 2.4 x86 Driver Update Guide for additional restrictions on conﬁguring

the NE2000 and other Ethernetcards in the same system.
