> On the code after the below commits, the criteria to select the IPV4 or
> IPV6 hash functions was the existence of some ETH_RSS_IPV4 RSS types on
> the flow rule.
> 
> The check is wrong. For example ETH_RSS_NONFRAG_IPV4_TCP will not
> select the IPV4 hash which will cause the packet to be spread in a bad way.
> 
> Fix it by adding the corresponding types needed for each hash selection.

> On v2:
>  * Removed duplicated ETH_RSS_NONFRAG_IPV6_OTHER flag.
