You want RTE_FLOW_ACTION_TYPE_RSS

uint16_t queue_indices[] = {10, 11, 12, 13, 14, 15};
struct rte_flow_action_rss rss = {
        .types =  RTE_ETH_RSS_UDP | RTE_ETH_RSS_TCP,
        .queue_num = RTE_DIM(queue_indicies),
        .queue = queue_indicies,
};

struct rte_flow_action action[]={
     [0]={.type = RTE_FLOW_ACTION_TYPE_RSS,.conf = &rss},
    [1]={.type = RTE_FLOW_ACTION_TYPE_END}
};

Yes, drivers implement only what hardware can support.
