Currently, when use 'flow' command to create a rule that combine with
several RSS types, even the RSS type combination is invalid, it also
be created successfully.
Here list some invalid RSS combinations:
- ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_TCP
- ETH_RSS_IPV6 | ETH_RSS_NONFRAG_IPV6_TCP
For 'ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_TCP' (same as IPV6), this
pathch adds these combinations in 'invalid_rss_comb' array to do
valid check, if the combination check failed, the rule will be created
unsuccessful.
