252 * therefore down for now. phy_timer will set this state when it

254 * whenever called with phydev->autoneg set to AUTONEG_ENABLE.

256 * the state to NOLINK.

258 * and calls adjust_link
259 * - If autonegotiation did not finish after an arbitrary amount
260 * of time, autonegotiation should be tried again if the PHY
261 * supports "magic" autonegotiation (back to AN)
262 * - If it didn't finish, and no magic_aneg, move to FORCING.
264 * NOLINK: PHY is up, but not currently plugged in.
265 * - If the timer notes that the link comes back, we move to RUNNING
266 * - config_aneg moves to AN
267 * - phy_stop moves to HALTED
269 * FORCING: PHY is being configured with forced settings

272 * retry (FORCING) after a timeout
273 * - phy_stop moves to HALTED
275 * RUNNING: PHY is currently up, running, and possibly sending
276 * and/or receiving packets
277 * - timer will set CHANGELINK if we're polling (this ensures the
278 * link state is polled every other cycle of this state machine,
279 * which makes it every other second)
280 * - irq will set CHANGELINK
281 * - config_aneg will set AN
282 * - phy_stop moves to HALTED
284 * CHANGELINK: PHY experienced a change in link state
285 * - timer moves to RUNNING if link
286 * - timer moves to NOLINK if the link is down
287 * - phy_stop moves to HALTED
289 * HALTED: PHY is up, but no polling or interrupts are done. Or
290 * PHY is in an error state.
292 * - phy_start moves to RESUMING
294 * RESUMING: PHY was halted, but now wants to run again.
