If it is still relevant then I think it needs to be revisited, by being reposted after appropriate preparation. As such I'm marking this patch-set as "Deferred" in patchwork. No action is required unless there is a desire to revisit this patch-set.
This series adds support offloading multiple "output"/"clone" actions within one datapath flow. Some cases which require sending a packet to multiple destinations is not currently offloaded, HWOL can be done by translating the fate actions "output" and "clone" into rte_flow_action_sample actions with ratio=1, this means 100% of the traffic will be mirrored. Such datapath rules can be offloaded by embedding each non-last output/clone action into an RTE_FLOW_ACTION_TYPE_SAMPLE with ratio=1. Currently there are two types on mutiple destination outputs, forward to port (local), or encapsulate a packet and forward to a remote server (remote). Add support for those cases by having the sample action be either RTE_FLOW_ACTION_TYPE_PORT_ID for local destinations, or RTE_FLOW_ACTION_TYPE_RAW_ENCAP for remote destinations. This patch is a rebased version of [1]. *V2: - Fix build issues due to a missing patch in V1. - Link to Github Actions with a passing build for this series [2].
