Acknowledge
1 = Link partner ability data reception acknowledged
0 = Not acknowledged
The PHY's auto-negotiation state machine will automatically control
this bit from the incoming FLP bursts. Software should not attempt
to write to this bit
Remote Fault
1 = Remote fault indicated by link partner
0 = No remote fault indicated by link partner
Reserved
Write as 0, ignore on read
Flow Control Support
1 = Controller chip supports flow control ability by link partner
0 = Controller chip doesn’t support flow control ability by link
partner
100BASE-T4 Support
1 = 100BASE-T4 is supported by the link partner
0 = 100BASE-T4 is not supported by the link partner
100BASE-TX Full Duplex Support
