261 | * - PHY driver probe function will, depending on the PHY, set | |
262 | * the state to STARTING or READY | |
263 | * | |
264 | * STARTING: PHY device is coming up, and the ethernet driver is | |
265 | * not ready. PHY drivers may set this in the probe function. | |
266 | * If they do, they are responsible for making sure the state is | |
267 | * eventually set to indicate whether the PHY is UP or READY, | |
268 | * depending on the state when the PHY is done starting up. | |
269 | * - PHY driver will set the state to READY | |
270 | * - start will set the state to PENDING | |
271 | * | |
272 | * READY: PHY is ready to send and receive packets, but the | |
273 | * controller is not. By default, PHYs which do not implement | |
274 | * probe will be set to this state by phy_probe(). If the PHY | |
275 | * driver knows the PHY is ready, and the PHY state is STARTING, | |
276 | * then it sets this STATE. | |
277 | * - start will set the state to UP | |
278 | * | |
279 | * PENDING: PHY device is coming up, but the ethernet driver is | |
280 | * ready. phy_start will set this state if the PHY state is | |
281 | * STARTING. | |
282 | * - PHY driver will set the state to UP when the PHY is ready | |
283 | * | |
284 | * UP: The PHY and attached device are ready to do work. | |
285 | * Interrupts should be started here. | |
286 | * - timer moves to AN | |
287 | * | |
288 | * AN: The PHY is currently negotiating the link state. Link is | |
289 | * therefore down for now. phy_timer will set this state when it | |
290 | * detects the state is UP. config_aneg will set this state | |
291 | * whenever called with phydev->autoneg set to AUTONEG_ENABLE. | |
292 | * - If autonegotiation finishes, but there's no link, it sets | |
293 | * the state to NOLINK. | |
294 | * - If aneg finishes with link, it sets the state to RUNNING, | |
295 | * and calls adjust_link | |
296 | * - If autonegotiation did not finish after an arbitrary amount | |
297 | * of time, autonegotiation should be tried again if the PHY | |
298 | * supports "magic" autonegotiation (back to AN) | |
299 | * - If it didn't finish, and no magic_aneg, move to FORCING. | |
300 | * | |
301 | * NOLINK: PHY is up, but not currently plugged in. | |
302 | * - If the timer notes that the link comes back, we move to RUNNING | |
303 | * - config_aneg moves to AN | |
304 | * - phy_stop moves to HALTED | |
305 | * | |
306 | * FORCING: PHY is being configured with forced settings | |
307 | * - if link is up, move to RUNNING | |
308 | * - If link is down, we drop to the next highest setting, and | |
309 | * retry (FORCING) after a timeout | |
310 | * - phy_stop moves to HALTED | |
311 | * | |
312 | * RUNNING: PHY is currently up, running, and possibly sending | |
313 | * and/or receiving packets | |
314 | * - timer will set CHANGELINK if we're polling (this ensures the | |
315 | * link state is polled every other cycle of this state machine, | |
316 | * which makes it every other second) | |
317 | * - irq will set CHANGELINK | |
318 | * - config_aneg will set AN | |
319 | * - phy_stop moves to HALTED | |
320 | * | |
321 | * CHANGELINK: PHY experienced a change in link state | |
322 | * - timer moves to RUNNING if link | |
323 | * - timer moves to NOLINK if the link is down | |
324 | * - phy_stop moves to HALTED | |
325 | * | |
326 | * HALTED: PHY is up, but no polling or interrupts are done. Or | |
327 | * PHY is in an error state. | |
328 | * | |
329 | * - phy_start moves to RESUMING | |
330 | * | |
331 | * RESUMING: PHY was halted, but now wants to run again. | |
