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 return the 6 octet 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 octet Ethernet address currently
associated (attached) to this stream. The credentials of the process which originally
opened this stream must be superuser. Otherwise 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 is successful on this stream. Once changed, all streams
subsequently opened and attached to this device will obtain this new physical address.
The physical address will remain until this primitive is used to change the physical
address again or the system is rebooted, whichever comes first.

DIAGNOSTICS There are too many driver messages to list them all individuallyhere. Some of the more
common messages and their meanings follow.
ie%d: Ethernet jammed
Network activity has become so intense that successive transmission attempts
failed, and the 82586 gave up on the current packet. Another possible cause of
this message is a noise source somewhere in the network, such as a loose tran-
sceiver connection.
ie%d: no carrier
The 82586 has lost input to its carrier detect pin while tryingto transmit a packet,
causing the packet to be dropped. Possible causes include an open circuit some-
where in the network and noise on the carrier detect line from the transceiver.
NOTES netstat −i command (see netstat(1M)) will display the number of collisions of a packet
transmission before a packet is successfully transmitted.
