    For data capture, the RGMII external PHY offers an option to add delay to RX_CLK. When you enable the option to delay RX_CLK at the external PHY device, the PHY device transmits a clock that is center-aligned with the data and waveforms, as shown in Figure 10. Thus, the FPGA and HardCopy ASIC can capture the incoming data

    The SMSC PHY uses the RMII interface and supports 10100 Mbs Figure 5 from CMPS 211 at American University of BeirutSo it turns out an RMII Phy can talk to another RMII phy like this but the LAN9303 can't be connected directly to another LAN9303 as described. The problem is that timing of the DV D0 and D1 signals coming out of one LAN9303 don't meet the requirements for DV D0 and D1 going into the other.
