``PHY_INTERFACE_MODE_25GBASER``

    This is the IEEE 802.3 PCS Clause 107 defined 25GBASE-R protocol.

    The PCS is identical to 10GBASE-R, i.e. 64B/66B encoded

    running 2.5 as fast, giving a fixed bit rate of 25.78125 Gbaud.

    Please refer to the IEEE standard for further information.



``PHY_INTERFACE_MODE_100BASEX``

    This defines IEEE 802.3 Clause 24.  The link operates at a fixed data

    rate of 125Mpbs using a 4B/5B encoding scheme, resulting in an underlying
