100Mbs True Quiet Mode Enable:
1 = Transmit True Quiet Mode.
0 = Normal Transmit Mode.
Signal Detect Force PMA:
1 = Forces Signal Detection in PMA.
0 = Normal SD operation.
Signal Detect Option:
1 = Enhanced signal detect algorithm.
0 = Reduced signal detect algorithm.
Descrambler Timeout:
Increase the descrambler timeout. When set this should allow the
device to receive larger packets (>9k bytes) without loss of syn-
chronization.
