Polarity Reverse (polrvs)
1 = polarity is reversed.
0 = polarity is not reversed.
MDI-X Status (mdix_st)
1 = MDI
0 = MDI-X
Force Link (force_lnk)
1 = force link pass.
0 = normal operation.
Power Saving (pwrsave)
1 = disable power saving.
0 = enable power saving.
Remote (Near-End) Loopback (rlb)
1 = perform remote loopback at Port 1's PHY
(RXP1/RXM1 -> TXP1/TXM1, see Figure 16)

Reserved
Description
Vct_enable
1 = the cable diagnostic test is enabled. It is
self-cleared after the VCT test is done.
0 = it indicates the cable diagnostic test is
completed and the status information is valid
for read.
Vct_result
[00] = normal condition.
[01] = open condition detected in the cable.
[10] = short condition detected in the cable.
[11] = cable diagnostic test failed.
Vct 10M Short
1 = Less than 10m short.
Reserved
Vct_fault_count
Distance to the fault. The distance is
approximately 0.4m*vct_fault_count.
