The validity verification of input parameters should be performed at
API layer, not in the PMD.

This set of patches fix miss input validation.

The function updated in ethdev header file, and the ethdev .c file seems mixes 
within the patches [1], can you please send a new version to fix it, you can 
keep the acks to this version.

The validity verification of input parameters should be performed at
API layer, not in the PMD.

This set of patches fix miss input validation.
