Hi Stephen,
Thanks for your response.

As our application has limitations while using RSS,=  
I wo= uld prefer a similar approach to RTE_ACTION_TYPE_QUEUE.

Since flow director supports only one RXQ index, I = could not be able to achieve desired outcome.

Please suggest if any approach like RTE_ACTION_TYPE= _QUEUE but not RSS could match my requirement.

Thanks,
Raghavan V

You want RTE_FLOW_ACTION_TYPE_RSS

uint16_t queue_indices[] =3D {10, 11, 12, 13, 14, 15};
struct rte_flow_action_rss rss =3D {
        .types =3D  RTE_ETH_RSS_UDP= | RTE_ETH_RSS_TCP,
        .queue_num =3D RTE_DIM(queue_ind= icies),
        .queue =3D queue_indicies,
};

struct rte_flow_action action[]=3D{
     [0]=3D{.type =3D RTE_FLOW_ACTION_TYPE_RSS,.conf = =3D &rss},
    [1]=3D{.type =3D RTE_FLOW_ACTION_TYPE_END}
};

> Is this action limited to drivers specific?
Yes, drivers implement only what hardware can support.
