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

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,

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.
