Any ideas ?

Yes , 19110cfbb34d4af0cdfe14cd243f3b09dc95b013 broke it.

See:

Hi,

Digging into this, the problem is complicated. The original bug assumed behavior
of the .check_for_link call, which is universally not implemented.

I think the correct fix is to revert 19110cfbb34d ("e1000e: Separate signaling for
link check/link up", 2017-10-10) and find a more proper solution.

I don't think any other code which uses check_for_link expects the interface to
return in the way this patch attempted.

Alternatively, we can go a step farther and make sure every implementation of .check_for_link follows the modified interface.

We are at -rc3 now. Reverting 19110cfbb34d seems like good solution at
the moment.
