Always reads 0
Read will return 1 indicating extended status information is held in
register 0x0F.
Read will return 0 indicating MDIO doesn’t accept command without
preceding preamble (minimum 32 1’s). Writes will be ignored
Always reads 0 (AN not supported)
Always reads 0
Read will return 0, indicating that Auto negotiation is not supported
Read will return the Link Status and is valid only when device is in
GMII/RGMII mode or when bit 17.7 is set in Non-GMII/RGMII modes.
Note: Link status will always indicate high when in loopback. In remote
loopback mode, the bit represents the normal bit function.
1 = Link UP
0 = Link DOWN
Always reads 0
Read will return 1 indicating extended register capability
