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.
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
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
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
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
286 * HALTED: PHY is up, but no polling or interrupts are done. Or
287 * PHY is in an error state.
289 * - phy_start moves to RESUMING
291 * RESUMING: PHY was halted, but now wants to run again.
