Thank you Andrew for the review. I fully understand your point.
I would like to propose that I put that on my ToDo list and fix
that in a follow-on patch to net-next.

The fields in the link_info control blocks are used today to generate
other values (e.g. supported speed) which will not work with *_UNKNOWN,
so the follow-on patch will be more than just 2 lines.
These 2 patches under review are required to solve a recovery problem, 
so I would like them to go to net asap.

Would that be ok for you?
