[dpdk-dev] [PATCH v2] net/iavf: fix negative GTP-U flow rules create successfully

[Murphy Yang]

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
