Far-End Line loopback verifies Line interface is communicating with the PHY. It is enabled by bit 4 of the PMODE
register (0x04). When line loopback is enabled for a given port, all data received by the M2852x on that port is
processed by the Receive Line Interface and transmitted out the line interface. Data from the Transmit UTOPIA bus
is ignored.

General Note:
Framer
Configuring a port for line loopback mode disables all UTOPIA signals for that port.
