And if targeting next-release 26.03 the ABI is not allowed to change. That means you will need to put the new flow actions at the end of the enum rte_flow_action_type so that values don't get reordered. Release Dates ------------- The following are the proposed working dates for 25.11: - Proposal deadline (RFC/v1 patches): 31 August 2025 - API freeze (-rc1): 24 October 2025 - PMD features freeze (-rc2): 7 November 2025 - Builtin applications features freeze (-rc3): 17 November 2025 - Release: 26 November 2025 See https://core.dpdk.org/roadmap/
