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
- ETH_RSS_GTPU | ETH_RSS_IPV4
- ETH_RSS_GTPU | ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_UDP
- ETH_RSS_GTPU | ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_TCP
- ETH_RSS_GTPU | ETH_RSS_IPV6
- ETH_RSS_GTPU | ETH_RSS_IPV6 | ETH_RSS_NONFRAG_IPV6_UDP
- ETH_RSS_GTPU | ETH_RSS_IPV6 | ETH_RSS_NONFRAG_IPV6_TCP
So, this patch adds these combinations in 'invalid_rss_comb'
array to do valid check, if the combination check failed,
the rule will be created unsuccessful.
