 165  * given that the PHY device exists.
 166  * - PHY driver probe function will, depending on the PHY, set
 167  * the state to STARTING or READY
 168  *
 169  * STARTING:  PHY device is coming up, and the ethernet driver is
 170  * not ready.  PHY drivers may set this in the probe function.
 171  * If they do, they are responsible for making sure the state is
 172  * eventually set to indicate whether the PHY is UP or READY,
 173  * depending on the state when the PHY is done starting up.
 174  * - PHY driver will set the state to READY
 175  * - start will set the state to PENDING
 176  *
 177  * READY: PHY is ready to send and receive packets, but the
 178  * controller is not.  By default, PHYs which do not implement
 179  * probe will be set to this state by phy_probe().  If the PHY
 180  * driver knows the PHY is ready, and the PHY state is STARTING,
 181  * then it sets this STATE.
 182  * - start will set the state to UP
 183  *
 184  * PENDING: PHY device is coming up, but the ethernet driver is
 185  * ready.  phy_start will set this state if the PHY state is
 186  * STARTING.
 187  * - PHY driver will set the state to UP when the PHY is ready
 188  *
 189  * UP: The PHY and attached device are ready to do work.
 190  * Interrupts should be started here.
 191  * - timer moves to AN
 192  *
 193  * AN: The PHY is currently negotiating the link state.  Link is
 194  * therefore down for now.  phy_timer will set this state when it
 195  * detects the state is UP.  config_aneg will set this state
 196  * whenever called with phydev->autoneg set to AUTONEG_ENABLE.
 197  * - If autonegotiation finishes, but there's no link, it sets
 198  *   the state to NOLINK.
 199  * - If aneg finishes with link, it sets the state to RUNNING,
 200  *   and calls adjust_link
 201  * - If autonegotiation did not finish after an arbitrary amount
 202  *   of time, autonegotiation should be tried again if the PHY
 203  *   supports "magic" autonegotiation (back to AN)
 204  * - If it didn't finish, and no magic_aneg, move to FORCING.
 205  *
 206  * NOLINK: PHY is up, but not currently plugged in.
 207  * - If the timer notes that the link comes back, we move to RUNNING
 208  * - config_aneg moves to AN
 209  * - phy_stop moves to HALTED
 210  *
 211  * FORCING: PHY is being configured with forced settings
 212  * - if link is up, move to RUNNING
 213  * - If link is down, we drop to the next highest setting, and
 214  *   retry (FORCING) after a timeout
 215  * - phy_stop moves to HALTED
 216  *
 217  * RUNNING: PHY is currently up, running, and possibly sending
 218  * and/or receiving packets
 219  * - timer will set CHANGELINK if we're polling (this ensures the
 220  *   link state is polled every other cycle of this state machine,
 221  *   which makes it every other second)
 222  * - irq will set CHANGELINK
 223  * - config_aneg will set AN
 224  * - phy_stop moves to HALTED
 225  *
 226  * CHANGELINK: PHY experienced a change in link state
 227  * - timer moves to RUNNING if link
 228  * - timer moves to NOLINK if the link is down
 229  * - phy_stop moves to HALTED
 230  *
 231  * HALTED: PHY is up, but no polling or interrupts are done. Or
 232  * PHY is in an error state.
 233  *
 234  * - phy_start moves to RESUMING
 235  *
 236  * RESUMING: PHY was halted, but now wants to run again.
 237  * - If we are forcing, or aneg is done, timer moves to RUNNING
 238  * - If aneg is not done, timer moves to AN
