  In i40e FDIR PMD code for checking programming status,
when the action of add FDIR filter is ok, i40e NIC will
not write back to programming status descriptor, so if
PMD code check DD is not done after period of time dealy,
it means the add or remove filter action is ok. It only write
back descriptor when fail.
