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 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.
Once changed, the physical address will remain until this primitive is used to change the
physical address again or the system is rebooted, whichever comes first.

SPARCstation 10 Twisted-Pair Ethernet Link Test
Twisted-Pair Ethernet Link Test
DIAGNOSTICS le%d: msg too big: %d
The message lengthexceeded ETHERMAX.
le%d: Babble error − sent a packet longer than 1518 bytes
While transmitting a packet, the LANCE chip has noticed that the packet’s length
exceeds the maximum allowed for Ethernet. This error indicates a kernel bug.
le%d: No carrier − transceiver cable problem?
The LANCE chip has lost input to its carrier detect pin while trying to transmit a
packet.
le%d: Memory Error!
The LANCE chip timed out while trying to acquire the bus for a DVMA transfer.
NOTES If you are using twisted pair Ethernet (TPE), you need to be aware of the linktest feature.
The IEEE 10Base-T specification states that the link test should always be enabled at the
host and the hub. Complications may arise because:
1. Some older hubs do not provide link pulses
2. Some hubs are configured to not send linkpulses
