1000BASE-X Full Duplex Support:
1 = 1000BASE-X is supported by the local device.
0 = 1000BASE-X is not supported.
DP83865 does not support 1000BASE-X and bit should always
be read back as “0”.
1000BASE-X Half Duplex Support:
1 = 1000BASE-X is supported by the local device.
0 =1000BASE-X is not supported.
DP83865 does not support 1000BASE-X and bit should always
be read back as “0”.
1000BASE-T Full Duplex Support:
1 = 1000BASE-T is supported by the local device.
0 =1000BASE-T is not supported.
1000BASE-T Half Duplex Support:
