* Marvell 10G 88x3310 PHY driver
|
|
*
|
|
* Based upon the ID registers, this PHY appears to be a mixture of IPs
|
|
* from two different companies.
|
|
*
|
|
* 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 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.
