> NFP plans support RTE_FLOW_ACTION_TYPE_MODIFY_FIELD flow action in > 24.07 or 24.11. > For remove of legacy flow, does there also correspond patches in OVS project? I am not familiar with any patches to OVS. Thanks for raising this.
For the record, in latest commit on main branch in OVS (commit fa0dfa18d534) I see that the following modify actions are used: RTE_FLOW_ACTION_TYPE_SET_MAC_SRC RTE_FLOW_ACTION_TYPE_SET_MAC_DST RTE_FLOW_ACTION_TYPE_SET_IPV4_SRC RTE_FLOW_ACTION_TYPE_SET_IPV4_DST RTE_FLOW_ACTION_TYPE_SET_TTL RTE_FLOW_ACTION_TYPE_SET_TP_SRC RTE_FLOW_ACTION_TYPE_SET_TP_DST RTE_FLOW_ACTION_TYPE_SET_IPV6_SRC RTE_FLOW_ACTION_TYPE_SET_IPV6_DST We'd need to sync with OVS developers, but I assume we cannot just remove these without providing a proper replacement, so the functionality is not broken. I think that, once there's an agreement on the timeline of implementing MODIFY_FIELD in PMDs, we'd need to work with OVS to migrate it to MODIFY_FIELD. After OVS uses MODIFY_FIELD actions, deprecated actions could be safely removed from OVS and DPDK. What do you all think? Also, this opens a question about other upstream projects using deprecated actions. Do you know if there are other projects besides OVS? Best regards, Dariusz Sosnowski
