This patch series is based on two axioms: - During autoneg a PHY always reports the link being down
- Info in clause 22/45 registers doesn't allow to differentiate between these two states: 1. Link is physically down 2. A link partner is connected and PHY is autonegotiating In both cases "link up" and "aneg finished" bits aren't set. One consequence is that having separate states PHY_NOLINK and PHY_AN isn't needed. By using these two axioms the state machine can be significantly simplified.
