+ * - PHY driver will set the state to READY
+ * - start will set the state to PENDING
+ *
+ * READY: PHY is ready to send and receive packets, but the
+ * controller is not.  By default, PHYs which do not implement
+ * probe will be set to this state by phy_probe().  If the PHY
+ * driver knows the PHY is ready, and the PHY state is STARTING,
+ * then it sets this STATE.
+ * - start will set the state to UP
+ *
+ * PENDING: PHY device is coming up, but the ethernet driver is

+ * STARTING.

+ * AN: The PHY is currently negotiating the link state.  Link is

+ * detects the state is UP.  config_aneg will set this state
+ * whenever called with phydev->autoneg set to AUTONEG_ENABLE.
+ * - If autonegotiation finishes, but there's no link, it sets
+ *   the state to NOLINK.
+ * - If aneg finishes with link, it sets the state to RUNNING,
+ *   and calls adjust_link
+ * - If autonegotiation did not finish after an arbitrary amount
+ *   of time, autonegotiation should be tried again if the PHY
+ *   supports "magic" autonegotiation (back to AN)
+ * - If it didn't finish, and no magic_aneg, move to FORCING.
+ *
+ * NOLINK: PHY is up, but not currently plugged in.
+ * - If the timer notes that the link comes back, we move to RUNNING
+ * - config_aneg moves to AN
+ * - phy_stop moves to HALTED
+ *
+ * FORCING: PHY is being configured with forced settings
+ * - if link is up, move to RUNNING
+ * - If link is down, we drop to the next highest setting, and
+ *   retry (FORCING) after a timeout
+ * - phy_stop moves to HALTED
+ *
+ * RUNNING: PHY is currently up, running, and possibly sending
+ * and/or receiving packets
+ * - timer will set CHANGELINK if we're polling (this ensures the
+ *   link state is polled every other cycle of this state machine,
+ *   which makes it every other second)
+ * - irq will set CHANGELINK
+ * - config_aneg will set AN
+ * - phy_stop moves to HALTED
+ *
+ * CHANGELINK: PHY experienced a change in link state
+ * - timer moves to RUNNING if link
+ * - timer moves to NOLINK if the link is down
+ * - phy_stop moves to HALTED
+ *
+ * HALTED: PHY is up, but no polling or interrupts are done. Or
+ * PHY is in an error state.
+ *
+ * - phy_start moves to RESUMING
+ *
+ * RESUMING: PHY was halted, but now wants to run again.
