0x0
1 = Downshift
0 = No Downshift
0x0
1 = Sleep
0 = Active
0x0
1 = Copper link is up
0 = Copper link is down
0x0
1 = Link partner needs DTE power
0 = Link partner does not need DTE power
1 = Reversed
0 = Normal
0x0
Polarity reversal can be disabled by writing to Register
16_0.1. In 1000BASE-T mode, polarity of all pairs are
shown in Register 21_5.3:0.
