/*
 * 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.
