So, it's wrong to use it to set the VF MAC address. As this API is also used by the VMDq example, ideally we need a parameter to tell the pool is VMDq or VF. But it's hard to change it because of the ABI change concern. Now the solution is to provide a new API, users can call it to add VF MAC address from PF on i40e.
