178 : : * STARTING.
179 : : * - PHY driver will set the state to UP when the PHY is ready
180 : : *
181 : : * UP: The PHY and attached device are ready to do work.
182 : : * Interrupts should be started here.
183 : : * - timer moves to AN

185 : : * AN: The PHY is currently negotiating the link state. Link is

188 : : * whenever called with phydev->autoneg set to AUTONEG_ENABLE.
189 : : * - If autonegotiation finishes, but there's no link, it sets
190 : : * the state to NOLINK.
191 : : * - If aneg finishes with link, it sets the state to RUNNING,
192 : : * and calls adjust_link
193 : : * - If autonegotiation did not finish after an arbitrary amount
194 : : * of time, autonegotiation should be tried again if the PHY
195 : : * supports "magic" autonegotiation (back to AN)
196 : : * - If it didn't finish, and no magic_aneg, move to FORCING.
197 : : *
198 : : * NOLINK: PHY is up, but not currently plugged in.
199 : : * - If the timer notes that the link comes back, we move to RUNNING
200 : : * - config_aneg moves to AN
201 : : * - phy_stop moves to HALTED
202 : : *
203 : : * FORCING: PHY is being configured with forced settings
204 : : * - if link is up, move to RUNNING
205 : : * - If link is down, we drop to the next highest setting, and
206 : : * retry (FORCING) after a timeout
207 : : * - phy_stop moves to HALTED
208 : : *
209 : : * RUNNING: PHY is currently up, running, and possibly sending
210 : : * and/or receiving packets
211 : : * - timer will set CHANGELINK if we're polling (this ensures the
212 : : * link state is polled every other cycle of this state machine,
213 : : * which makes it every other second)
214 : : * - irq will set CHANGELINK
215 : : * - config_aneg will set AN
216 : : * - phy_stop moves to HALTED
217 : : *
218 : : * CHANGELINK: PHY experienced a change in link state
219 : : * - timer moves to RUNNING if link
220 : : * - timer moves to NOLINK if the link is down
221 : : * - phy_stop moves to HALTED
222 : : *
223 : : * HALTED: PHY is up, but no polling or interrupts are done. Or
224 : : * PHY is in an error state.
225 : : *
