primitives are accepted by the driver in any state following DL_ATTACHED.

The DL_PROMISCON_REQ and DL_PROMISCOFF_REQ primitives with the

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

(“promiscuous mode”) frames on the media including frames generated by the local host.

When used with the DL_PROMISC_SAP ﬂag set, this enables/disables reception 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

associated (attached) to the stream in the DL_PHYS_ADDR_ACK primitive. This primi-

tive is valid only in states following a successful DL_ATTACH_REQ.

The DL_SET_PHYS_ADDR_REQ primitive changes the 6-octet Ethernet address

currently associated (attached) to this stream. The credentials of the process that origi-

nally opened this stream must be superuser or EPERM 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. Once changed, the 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/pe.conf ﬁle supports the following options:

intr Speciﬁes the IRQ level for the parallel port that the Xircom Adapter is con-

nected to.

ioaddr Speciﬁes the I/O address for the parallel port that the Xircom Adapter is

connected to.

It is important to ensure that there are no conﬂicts for the adapter’s I/O port or IRQ level.
