I don't know whether the case "Count only" should fail or means passthru + count.
In my code, I return error when in the case "count only":
if (dest_num + mark_num == 0) {
rte_flow_error_set(error, EINVAL,
RTE_FLOW_ERROR_TYPE_ACTION, actions,
"Emtpy action");
return -rte_errno;
}
So I want to confirm how to define "count only" case here, your suggestion code seems "count only" means "count + passthru" ?
Thanks
