0: No remote fault indication detected
When in 100FX mode, this bit means in-band signal Far-
End-Fault is detected. Refer to section 7.6.4 Far-End-Fault-
Indication, page 32.
This bit will remain set until it is cleared by reading
register 1 via the management interface.
1: NWay auto negotiation capable (permanently =1)
0: No auto negotiation capability
1: Link has not failed since previous read
0: Link has failed since previous read
If the link fails, this bit will be set to 0 until read.
1: Jabber detected.

The jabber function is disabled in 100Base-X mode. Jabber
is supported only in 10Base-T mode.
Extended Capability 1: Extended register capable (permanently =1)
0: Not extended register capable
100Base_T4 – The RTL8208B(F)-LF does not support the T4 function. Any reads to this bit will
return a ‘0’.
100Base_TX_FD – The RTL8208B(F)-LF is capable of operating in 100Base-TX full duplex mode.
100Base_TX_HD – The RTL8208B(F)-LF is capable of operating in 100Base-TX half duplex mode.
10Base_T_FD – The RTL8208B(F)-LF is capable of operating in 10Base-T full duplex mode.
10Base_T_HD – The RTL8208B(F)-LF is capable of operating in 10Base-T half duplex mode.
