The device is generating a spurious PHY event after LPM state change
and the patch is ignoring the event once after state change. It's a
bit too specific. Maybe we should do this timeout-based - e.g. ignore
phy events for 1s after LPM state change. Gabriele, would be
interested in making such changes?

Thanks.
