TX_LPI_RCVD

The transmit LPI received bit is a latched version of TX_LPI. When this bit goes

high, it latches high until it is unlatched by reading.

0x0

1: transmit PCS has received LPI.

0: LPI not received.

RX_LPI_RCVD

The receive LPI received bit is a latched version of RX_LPI. When this bit goes high,

it latches high until it is unlatched by reading.

0x0

1: receive PCS has received LPI.

0: LPI not received.
