1 = extended register capabilities (permanently set)
0 = basic register set capabilities only
1 = Jabber condition detected
0 = No jabber condition detected. (default)
This bit has meaning only in 10Mbit/s modes.This bit is implemented
with a latching function so that the occurrence of a jabber condition
causes it to become set until it is cleared by a read to this register by
the management interface.
1 = Link is up indicates that the XCVR has determined that a valid link
has been established.
0 = Link is down (default)
The link status bit is implemented with a latching function, so that the
occurrence of a link failure condition causes the Link status bit to
become cleared and remain cleared until it is read via the management
interface. After the read, this bit will latch the XCVR link status at the
end of the read.
1 = Auto-negotiation Available (permanently set)
0 = Auto negotiation not available.
1 = Remote fault detected
0 = No remote fault detected(default)
This bit is cleared on read. When the RF bit in the received base Link
Code Word is set to logic one, this Remote Fault bit will be set to one.
0 = Auto-negotiation not Completed(default)
1 = Accept management frames with preamble suppressed.
0=Not accept management frames with preamble suppressed.
