Hi Xuan, Previous patches puts the code without enabling them, this last patch registers the PMD with lots of new code, it is hard to review this PMD. I think "OCTEON TX2" which also submitted this release [1] is good sample of how building the PMD incrementally, feature by feature, can you please check it?
