I want to reuse it in hash filter, so just put it in public header but ignore rte_eth_dev_prefix and function name.
I reconsider it and think put it in C file is much better.
I will send the next version based on your advice.
As for need it in driver, because when creating a flow, PMD driver should check its RSS types of its own side. It has nothing to do with etherdev.
