So files under base/ strictly copies of what is in this other Intel
repository (ND) or there are modifications?
If IIRC rte_link was crafted so that matches e1000 (at least) so that link
reads can be done atomically. I think it makes more sense that ethdev has a
generic, device independent struct and that drivers handle the translation,
if necessary. Do we agree on this?
This can help us a lot.

I will go back and redesign commit 3 in the series once more. I will need
some time (other things in the pipeline). I would have appreciated rising
this red flag in one of the 6 previous versions.
