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?
