As a result of above concerns, I propose postponing this PMD to 17.05

The dependent rte_bus just get into main repo less than two weeks ago,
also this driver comes with a few new things first of its kind, and it
matters to make first samples correct.

I believe it is good to let the PMD be around a little more to give
chance to both PMD and rte_bus to become more mature.
