100BASE-T4 Capable:
0 = Device not able to perform 100BASE-T4 mode.
100BASE-TX Full Duplex Capable:
1 = Device able to perform 100BASE-TX in full duplex mode.
100BASE-TX Half Duplex Capable:
1 = Device able to perform 100BASE-TX in half duplex mode.
10BASE-T Full Duplex Capable:
1 = Device able to perform 10BASE-T in full duplex mode.
10BASE-T Half Duplex Capable:
1 = Device able to perform 10BASE-T in half duplex mode.
RESERVED: Write as 0, read as 0.
Preamble suppression Capable:
1 = Device able to perform management transaction with preamble
suppressed, 32-bits of preamble needed only once after reset, invalid
opcode or invalid turnaround.
0 = Normal management operation.
Auto-Negotiation Complete:
1 = Auto-Negotiation process complete.
0 = Auto-Negotiation process not complete.
Remote Fault:
1 = Remote Fault condition detected (cleared on read or by reset).
Fault criteria: Far End Fault Indication or notification from Link Part-
ner of Remote Fault.
0 = No remote fault condition detected.
Auto Negotiation Ability:
1 = Device is able to perform Auto-Negotiation.
0 = Device is not able to perform Auto-Negotiation.
Link Status:
1 = Valid link established (for either 10 or 100 Mb/s operation).
0 = Link not established.
The criteria for link validity is implementation specific. The occurrence
of a link failure condition will causes the Link Status bit to clear. Once
cleared, this bit may only be set by establishing a good link condition
and a read via the management interface.
Jabber Detect: This bit only has meaning in 10 Mb/s mode.
1 = Jabber condition detected.
0 = No Jabber.
This bit is implemented with a latching function, such that the occur-
rence of a jabber condition causes it to set until it is cleared by a read
to this register by the management interface or by a reset.
Extended Capability:
1 = Extended register capabilities.
0 = Basic register set capabilities only.
