This section describes how to connect the eTSEC to various interfaces: MII, GMII, RMII, RGMII, TBI,
and RTBI. To avoid confusion, all of the buses follow the bus conventions used in the IEEE 802.3
specification because the PHYs follow the same conventions. (For instance, in the bus TSECn_TXD[7:0],
bit 7 is the msb and bit 0 is the lsb). If a mode does not use all input signals available to a particular eTSEC,
those inputs that are not used must be pulled low on the board.
