The generic RTE_FLOW_ACTION_TYPE_MODIFY_FIELD action was introduced by [1]. This action provides an unified way to perform various arithmetic and transfer operations over packet network header fields and packet metadata.[1] commit 641dbe4fb053 ("net/mlx5: support modify field flow action") On other side there are a bunch of multiple legacy actions, that can be superseded by the generic MODIFY_FIELD action: RTE_FLOW_ACTION_TYPE_OF_SET_MPLS_TTL RTE_FLOW_ACTION_TYPE_OF_DEC_MPLS_TTL RTE_FLOW_ACTION_TYPE_OF_SET_NW_TTL RTE_FLOW_ACTION_TYPE_OF_DEC_NW_TTL sfc RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_OUT RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_IN RTE_FLOW_ACTION_TYPE_SET_IPV4_SRC bnxt, cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_SET_IPV4_DST bnxt, cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_SET_IPV6_SRC cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_SET_IPV6_DST cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_SET_TP_SRC cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_SET_TP_DST cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_DEC_TTL mlx5, sfc RTE_FLOW_ACTION_TYPE_SET_TTL mlx5 RTE_FLOW_ACTION_TYPE_SET_MAC_SRC cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_SET_MAC_DST cxgbe, mlx5 RTE_FLOW_ACTION_TYPE_INC_TCP_SEQ mlx5 RTE_FLOW_ACTION_TYPE_DEC_TCP_SEQ mlx5 RTE_FLOW_ACTION_TYPE_INC_TCP_ACK mlx5 RTE_FLOW_ACTION_TYPE_DEC_TCP_ACK mlx5 RTE_FLOW_ACTION_TYPE_SET_IPV4_DSCP mlx5 RTE_FLOW_ACTION_TYPE_SET_IPV6_DSCP mlx5 RTE_FLOW_ACTION_TYPE_OF_SET_VLAN_VID bnxt, cnxk, cxgbe, enic, mlx5, octeontx2, sfc RTE_FLOW_ACTION_TYPE_OF_SET_VLAN_PCP bnxt, cnxk, cxgbe, enic, mlx5, octeontx2, sfc RTE_FLOW_ACTION_TYPE_SET_TAG mlx5 RTE_FLOW_ACTION_TYPE_SET_META mlx5 This note deprecates the following RTE Flow actions, as not supported by any of PMDs: RTE_FLOW_ACTION_TYPE_OF_SET_MPLS_TTL RTE_FLOW_ACTION_TYPE_OF_DEC_MPLS_TTL RTE_FLOW_ACTION_TYPE_OF_SET_NW_TTL RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_OUT RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_IN The following actions are supposed to be deprecated in 22.07 and replaced by generic field modify action: RTE_FLOW_ACTION_TYPE_OF_DEC_NW_TTL RTE_FLOW_ACTION_TYPE_SET_IPV4_SRC RTE_FLOW_ACTION_TYPE_SET_IPV4_DST RTE_FLOW_ACTION_TYPE_SET_IPV6_SRC RTE_FLOW_ACTION_TYPE_SET_IPV6_DST RTE_FLOW_ACTION_TYPE_SET_TP_SRC RTE_FLOW_ACTION_TYPE_SET_TP_DST RTE_FLOW_ACTION_TYPE_DEC_TTL RTE_FLOW_ACTION_TYPE_SET_TTL RTE_FLOW_ACTION_TYPE_SET_MAC_SRC RTE_FLOW_ACTION_TYPE_SET_MAC_DST RTE_FLOW_ACTION_TYPE_INC_TCP_SEQ RTE_FLOW_ACTION_TYPE_DEC_TCP_SEQ RTE_FLOW_ACTION_TYPE_INC_TCP_ACK RTE_FLOW_ACTION_TYPE_DEC_TCP_ACK RTE_FLOW_ACTION_TYPE_SET_IPV4_DSCP RTE_FLOW_ACTION_TYPE_SET_IPV6_DSCP RTE_FLOW_ACTION_TYPE_SET_TAG RTE_FLOW_ACTION_TYPE_SET_META The VLAN set actions are interrelated to VLAN header insertion/removal and supported by multiple PMDs and widely used by applications and not supposed to be deprecated due to potential large impact on drivers and applications.

Thanks for the update, Acked-by: Ferruh Yigit <[email protected]> We need to follow with relevant PMD maintainers to switch to new 'MODIFY_FIELD' action till end of v22.07 release.
