This patch is not accepted in 17.11 for following reasons:
- it requires at least 3 acks
- we are not going to break API in 18.02, except maybe for EAL devargs
- the link mode is redundant with the speed capabilities
- such fields require work (and time) for every PMD to be fully supported
- we should discuss more generally which infos are in the scope of this function

Sorry for the short notice, I was waiting for comments and to see if
other deprecations were sent (or not) for ethdev.
