11. A method for data communication, comprising:
in a data-path module in an Ethernet Physical Layer (PHY) transceiver, the data-path module being coupled to a sensor and connected by a full-duplex Ethernet link of a communication network in a vehicle to a processor-transceiver that is coupled to a processor,
in an upstream direction to the processor-transceiver, transmitting data to the processor-transceiver over the Ethernet link at a selectable upstream data rate, and in a downstream direction from the processor-transceiver, receiving data from the processor-transceiver over the Ethernet link at a selectable downstream data rate; and
when the Ethernet PHY transceiver is operating in a field-operation mode for operating while the vehicle is operational, selecting the upstream data rate to be higher than the downstream data rate;
when the Ethernet PHY transceiver is operating in a diagnostic mode for performing a diagnostics procedure, the diagnostic mode being different from the field-operation mode, selecting the upstream data rate to be lower than the downstream data rate; and
configuring the data-path module to operate at the selected upstream data rate and the selected downstream data rate.
