Link status
Indicates whether or not the Ethernet communica-
tions interface is connected to an active network.
0 = inactive link
1 = active link

Half/full duplex
0 = Half duplex
1 = Full duplex
If the Link Status flag is 0, the value of the Half/Full
Duplex flag is indeterminate.

Negotiation
status
Indicates the status of the automatic autonegoti-
ation
0 = autonegotiation in progress
1 = autonegotiation and speed detection failed, Us-
ing default values for speed and duplex (10Mbps/
half duplex).
2 = auto-negotiation failed but detected speed (de-
fault: half duplex).
3 = successfully negotiated speed and duplex
4 = Autonegotiation not started, yet Forced speed
and duplex.
