+ * 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

* If both the fiber and copper ports are connected, the first to gain
* link takes priority and the other port is completely locked out.
