* There appears to be several different data paths through the PHY which
* are automatically managed by the PHY. The following has been determined
* via observation and experimentation:
* via observation and experimentation for a setup using single-lane Serdes:
*
* SGMII PHYXS -- BASE-T PCS -- 10G PMA -- AN -- Copper (for <= 1G)
* 10GBASE-KR PHYXS -- BASE-T PCS -- 10G PMA -- AN -- Copper (for 10G)
* 10GBASE-KR PHYXS -- BASE-R PCS -- Fiber
*
* With XAUI, observation shows:
*
* XAUI PHYXS -- <appropriate PCS as above>
*
* and no switching of the host interface mode occurs.
*
* If both the fiber and copper ports are connected, the first to gain
* link takes priority and the other port is completely locked out.
