OK.

Here there is another problem, the content and the format of the string
is not defined. In this patchset it is not same for different PMDs.
This is OK for just printing the data, but not good for an API. How can
the application know what to expect.

I believe this is better. But the problem we are having with this usage
is: ABI breakage.
Since this struct will be a public structure, in the future if we want
to add a new field to the struct, it will break the ABI, and just this
change will cause a new version for whole ethdev library!
When all required fields received via arguments, one by one, instead of
struct, at least ABI versioning can be done on the API when new field
added, and can be possible to escape from ABI breakage. But this will be
ugly when number of arguments increased.
Or any other opinion on how to define API to reduce ABI breakage?
