224 * DOWN: PHY device and driver are not ready for anything. probe
225 * should be called if and only if the PHY is in this state,
226 * given that the PHY device exists.
227 * - PHY driver probe function will, depending on the PHY, set
228 * the state to STARTING or READY
229 *
230 * STARTING: PHY device is coming up, and the ethernet driver is
231 * not ready. PHY drivers may set this in the probe function.
232 * If they do, they are responsible for making sure the state is
233 * eventually set to indicate whether the PHY is UP or READY,
234 * depending on the state when the PHY is done starting up.
235 * - PHY driver will set the state to READY
236 * - start will set the state to PENDING
237 *
238 * READY: PHY is ready to send and receive packets, but the
239 * controller is not. By default, PHYs which do not implement
240 * probe will be set to this state by phy_probe(). If the PHY
241 * driver knows the PHY is ready, and the PHY state is STARTING,
242 * then it sets this STATE.
243 * - start will set the state to UP
244 *
245 * PENDING: PHY device is coming up, but the ethernet driver is
246 * ready. phy_start will set this state if the PHY state is
247 * STARTING.
248 * - PHY driver will set the state to UP when the PHY is ready
249 *
250 * UP: The PHY and attached device are ready to do work.
251 * Interrupts should be started here.
252 * - timer moves to AN
253 *
254 * AN: The PHY is currently negotiating the link state. Link is
255 * therefore down for now. phy_timer will set this state when it
256 * detects the state is UP. config_aneg will set this state
257 * whenever called with phydev->autoneg set to AUTONEG_ENABLE.
258 * - If autonegotiation finishes, but there's no link, it sets
259 * the state to NOLINK.
260 * - If aneg finishes with link, it sets the state to RUNNING,
261 * and calls adjust_link
262 * - If autonegotiation did not finish after an arbitrary amount
263 * of time, autonegotiation should be tried again if the PHY
264 * supports "magic" autonegotiation (back to AN)
265 * - If it didn't finish, and no magic_aneg, move to FORCING.
266 *
267 * NOLINK: PHY is up, but not currently plugged in.
268 * - If the timer notes that the link comes back, we move to RUNNING
269 * - config_aneg moves to AN
270 * - phy_stop moves to HALTED
271 *
272 * FORCING: PHY is being configured with forced settings
273 * - if link is up, move to RUNNING
274 * - If link is down, we drop to the next highest setting, and
275 * retry (FORCING) after a timeout
276 * - phy_stop moves to HALTED
277 *
278 * RUNNING: PHY is currently up, running, and possibly sending
279 * and/or receiving packets
280 * - timer will set CHANGELINK if we're polling (this ensures the
281 * link state is polled every other cycle of this state machine,
282 * which makes it every other second)
283 * - irq will set CHANGELINK
284 * - config_aneg will set AN
285 * - phy_stop moves to HALTED
286 *
287 * CHANGELINK: PHY experienced a change in link state
288 * - timer moves to RUNNING if link
289 * - timer moves to NOLINK if the link is down
290 * - phy_stop moves to HALTED
291 *
292 * HALTED: PHY is up, but no polling or interrupts are done. Or
293 * PHY is in an error state.
294 *
295 * - phy_start moves to RESUMING
296 *
297 * RESUMING: PHY was halted, but now wants to run again.
298 * - If we are forcing, or aneg is done, timer moves to RUNNING
299 * - If aneg is not done, timer moves to AN
300 * - phy_stop moves to HALTED
