With inline IPsec processing, SA lookup would be happening in the Rx path of rte_ethdev. When rte_flow is configured to support more than one SA, SPI would be used to lookup SA. In such cases, additional verification would be required to ensure duplicate SPIs are not getting processed in the inline path. For lookaside cases, the same option can be used by application to offload tunnel verification to the PMD. These verifications would help in averting possible DoS attacks.
