Currently, when use 'flow' command to create a negative GTP-U rule, it
will be created successfully.

The list shows the impacted outer and inner 'ipv4' GTP-U patterns with
'ipv4' or 'gtpu' type:
 - iavf_pattern_eth_ipv4_gtpu_ipv4_udp
 - iavf_pattern_eth_ipv4_gtpu_eh_ipv4_udp
 - iavf_pattern_eth_ipv4_gtpu_ipv4_tcp
 - iavf_pattern_eth_ipv4_gtpu_eh_ipv4_tcp
 - more impacted patterns with 'gtpu' type:
   > iavf_pattern_eth_ipv4_gtpu_ipv4
   > iavf_pattern_eth_ipv4_gtpu_eh_ipv4

Same as the outer and inner 'ipv6' GTP-U patterns.

So, this commit adds the invalid RSS combinations in 'invalid_rss_comb'
array to make result correct.

The list of added invalid RSS combinations:
 - ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_TCP
 - ETH_RSS_IPV6 | ETH_RSS_NONFRAG_IPV6_TCP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV4
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV4_UDP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV4_TCP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV6
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV6_UDP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV6_TCP

Fixes: 91f27b2e39ab ("net/iavf: refactor RSS")

Seem that you add some specific negative flow case for the "ipv4(outer/inner) + gtpu" and "ipv4(outer/inner) + ipv4-udp(tcp)"  in the currently invalid checking mode, so you commit log could be more clear and clean for that, thanks.

Shouldn't it be " ETH_RSS_GTPU | ETH_RSS_IPV4" if outer ip case is the same? Whatever you should considerate both if you check one.
