 * - Auto-negotiation

 * The speed is configured at 1000 in the IF_MODE and BMCR MDIO registers
 * because the clock frequency is actually given by a PLL configured in the
 * Reset Configuration Word (RCW).
 * Since there is no difference between fixed speed SGMII w/o AN and 802.3z w/o
 * AN, we call this PHY interface type 2500Base-X. In case a PHY negotiates a
 * lower link speed on line side, the system-side interface remains fixed at
