For a generic PMD feature, completely agree with you. Application
shouldn't know/worry about underlying hardware. eth_dev layer should be
used.
But above usage is for an application that knows the hardware, and
knowing that it is losing all the benefits of the portability and
explicitly including the PMD header to use those PMD specific APIs.
