Subject: [dpdk-dev] [PATCH v6] net/iavf: fix invalid RSS combinations rule can be created
Date: Mon, 28 Dec 2020 02:28:36 +0000 [thread overview]
Message-ID: <20201228022836.41870-1-murphyx.yang@intel.com> (raw)
In-Reply-To: <20201224022044.84292-1-murphyx.yang@intel.com>
Currently, when use 'flow' command to create a rule that combine with
several RSS types, even the RSS type combination is invalid or unsupported,
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
Here list some currently unsupported RSS combinations:
- 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
For invalid RSS combinations, 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.
For unsupported RSS combinations, this patch adds these combinations in
'unsupported_rss_comb' array to do valid check, if the combination check
failed, the rule will be created unsuccessful.
Fixes: 91f27b2e39ab ("net/iavf: refactor RSS")

v6:
- add unsupported RSS combinations array.
v5:
- remove 'ETH_RSS_GTPU' from input set mask.
v4:
- use 'ETH_RSS_XXX' replace 'IAVF_RSS_TYPE_INNER_XXX'
v3:
- update the comments.
v2:
- add invalid RSS combinations.
