If we want to use link state change interrupt ste(4) should also implement auto-negotiation complete handler as well as various PHY access handling. Now link state change is handled by mii(4) polling so it will automatically update link state UP/DOWN events which in turn make ste(4) usable with lagg(4). r199559 added a private timer to drive watchdog and the timer also used to drive MAC statistics update. Because the MAC statistics update is called whenever statistics counter reaches near-full, it drove watchdog timer too fast such that it caused false watchdog timeouts under heavy TX traffic conditions. Fix the regression by separating ste_stats_update() from driving watchdog timer and introduce a new function ste_tick() that handles periodic job such as driving watchdog, MAC statistics update and link state check etc. While I'm here clear armed watchdog timer in ste_stop(). |
