5 Auto-Negotiation Complete RO 1 Auto-Negotiation Complete:
1 = Auto-Negotiation process completed
0 = Auto Negotiation process not completed (either still in process, disabled or reset)
4 Remote Fault RO, LH 0 Remote Fault:
1 = Remote fault condition detected
0 = No remote fault condition detected
Far End Fault indication or notification from Link Partner of Remote Fault. This bit is cleared on read or reset.
3 Auto-Negotiation Ability RO 0 Auto-Negotiation Ability:
1 = Device is able to perform Auto-Negotiation
0 = Device is not able to perform Auto-Negotiation
2 Link Status RO, LL 0 Link Status:
1 = Valid link established (for either 10-Mbps or 100-Mbps operation)
0 = Link not established
1 Jabber Detect RO, LH 0 Jabber Detect:
1 = Jabber condition detected
0 = No jabber condition detected
0 Extended Capability RO 1 Extended Capability:
1 = Extended register capabilities
0 = Basic register set capabilities only
