The only difference between RTE_PMD_I40E_PKG_OP_WR_ADD and RTE_PMD_I40E_PKG_OP_WR_ONLY is if need to change info list, right? Is there any difference between the profiles added? Do we need another CLI in testpmd to indicate how/when we need to use RTE_PMD_I40E_PKG_OP_WR_ONLY?

I believe that existing testpmd CLI is enough for i40e as this 'if' statement

OK, so track_id=0 is for RTE_PMD_I40E_PKG_OP_WR_ONLY. From the patch, it seems we needn't new operation RTE_PMD_I40E_PKG_OP_WR_ONLY exposed to application as PMD can decide if register WR_ONLY profiles by track_id.
