261 * of time, autonegotiation should be tried again if the PHY
262 * supports "magic" autonegotiation (back to AN)

282 * - config_aneg will set AN

285 * CHANGELINK: PHY experienced a change in link state
286 * - timer moves to RUNNING if link
287 * - timer moves to NOLINK if the link is down
288 * - phy_stop moves to HALTED
290 * HALTED: PHY is up, but no polling or interrupts are done. Or
291 * PHY is in an error state.
