Hi all, I created some ACLs in OVN, and want to trace each OVN-SB logical flow to the corresponding OVN-NB ACL table row. To achieve it, I refer to the "stage-hint" value of Logical_Flow.External_Ids and compare the UUID.
However, when multiple datapaths have the same ACL rule, these rules will be combined into a single logical flow with a logical_dp_group. The merged logical flow has only one "stage-hint" UUID value. Therefore, some OVN-NB ACL table rows can no longer be tracked in OVN-SB. Would it be possible to keep all stage-hint UUIDs when ovn-northd performs the flow combination? Or are there any workarounds to prevent an ACL from being merged? Currently, I am setting different names to each ACL to make them distinct. However, that also forces ACL logging that creates extra traffic overheads. Best, Qiaofeng
