| * 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. |
