     *
     * @description: 	The automatic MDI/MDI-X feature, also known as auto crossover, eliminates the need to determine whether to use a
     * 					straight cable or a crossover cable between the device and its link partner. The auto-sense function detects the MDI/
     * 					MDI-X pair mapping from the link partner, and assigns the MDI/MDI-X pair mapping of the device accordingly. Table 4-
     * 					1 shows the device’s 10/100/1000 Mbps pin configuration assignments for MDI and MDI-X pin mapping.

     *					Auto MDI/MDI-X is enabled by default. It can be disabled through the port control registers. If Auto MDI/MDI-X is dis-
     *					abled, the port control register can also be used to select between MDI and MDI-X settings.
     *					An isolation transformer with symmetrical transmit and receive data paths is recommended to support Auto MDI/MDI-X.
