+Link extended states:
- ============================ =============================================
- ``Autoneg failure`` Failure during auto negotiation mechanism
I think you need to define 'failure' here.
Linux PHYs don't have this state. auto-neg is either ongoing, or has completed. There is no time limit for auto-neg. If there is no link partner, auto-neg does not fail, it just continues until there is a link partner which responds and negotiation completes.
Looking at the state diagrams in 802.3 clause 28, what do you consider as failure?
