Selecting the Internal or External Transceiver

Use the use_int_xcvr parameter to change the default. For example, you can select the internal transceiver, even though the driver is capable of selecting the external transceiver. The driver, not the hardware, determines the internal and external transceiver.

If the external transceiver, which is connected to the MII interface, is present, the driver selects the external transceiver using the default use_int_xcvr 0. If the external transceiver is not present, the driver selects the internal transceiver. When this parameter is set to use_int_xcvr 1, the driver selects the internal transceiver, even if the external transceiver is connected.
