217 *
218 * DOWN: PHY device and driver are not ready for anything. probe
219 * should be called if and only if the PHY is in this state,
220 * given that the PHY device exists.
221 * - PHY driver probe function will, depending on the PHY, set
222 * the state to STARTING or READY
223 *
224 * STARTING: PHY device is coming up, and the ethernet driver is
225 * not ready. PHY drivers may set this in the probe function.
226 * If they do, they are responsible for making sure the state is
227 * eventually set to indicate whether the PHY is UP or READY,
228 * depending on the state when the PHY is done starting up.
229 * - PHY driver will set the state to READY
230 * - start will set the state to PENDING
231 *
232 * READY: PHY is ready to send and receive packets, but the
233 * controller is not. By default, PHYs which do not implement
234 * probe will be set to this state by phy_probe(). If the PHY
235 * driver knows the PHY is ready, and the PHY state is STARTING,
236 * then it sets this STATE.
237 * - start will set the state to UP
238 *
239 * PENDING: PHY device is coming up, but the ethernet driver is
240 * ready. phy_start will set this state if the PHY state is
241 * STARTING.
242 * - PHY driver will set the state to UP when the PHY is ready
243 *
244 * UP: The PHY and attached device are ready to do work.
245 * Interrupts should be started here.
246 * - timer moves to AN
247 *
248 * AN: The PHY is currently negotiating the link state. Link is
249 * therefore down for now. phy_timer will set this state when it
250 * detects the state is UP. config_aneg will set this state
251 * whenever called with phydev->autoneg set to AUTONEG_ENABLE.
252 * - If autonegotiation finishes, but there's no link, it sets
253 * the state to NOLINK.
254 * - If aneg finishes with link, it sets the state to RUNNING,
255 * and calls adjust_link
256 * - If autonegotiation did not finish after an arbitrary amount
257 * of time, autonegotiation should be tried again if the PHY
258 * supports "magic" autonegotiation (back to AN)
259 * - If it didn't finish, and no magic_aneg, move to FORCING.
260 *
261 * NOLINK: PHY is up, but not currently plugged in.
262 * - If the timer notes that the link comes back, we move to RUNNING
263 * - config_aneg moves to AN
264 * - phy_stop moves to HALTED
265 *
266 * FORCING: PHY is being configured with forced settings
267 * - if link is up, move to RUNNING
268 * - If link is down, we drop to the next highest setting, and
269 * retry (FORCING) after a timeout
270 * - phy_stop moves to HALTED
271 *
272 * RUNNING: PHY is currently up, running, and possibly sending
273 * and/or receiving packets
274 * - timer will set CHANGELINK if we're polling (this ensures the
275 * link state is polled every other cycle of this state machine,
276 * which makes it every other second)
277 * - irq will set CHANGELINK
278 * - config_aneg will set AN
279 * - phy_stop moves to HALTED
280 *
281 * CHANGELINK: PHY experienced a change in link state
282 * - timer moves to RUNNING if link
283 * - timer moves to NOLINK if the link is down
284 * - phy_stop moves to HALTED
285 *
286 * HALTED: PHY is up, but no polling or interrupts are done. Or
287 * PHY is in an error state.
288 *
289 * - phy_start moves to RESUMING
290 *
291 * RESUMING: PHY was halted, but now wants to run again.
292 * - If we are forcing, or aneg is done, timer moves to RUNNING
293 * - If aneg is not done, timer moves to AN
294 * - phy_stop moves to HALTED
