Optimize is a possible side effect of the operation, but there is no any promise that something will be optimized. I thought that current description explains what happens.

"white_list" suggests that it is guaranteed that nothing else will be reported. At least for me. However, I agree that set_supported is not nice and I accepted it just to keep API naming symmetric. May be it is really misleading here. May be just: rte_eth_dev_set_ptypes()?
