FDIR packet distribution with specific multiple RX queues.

Hi Team,

Is there any way to distribute packets evenly (Like RSS) to specific multiple RX queues in RTE_FLOW_ACTION_TYPE_QUEUE DPDK Flow director?

Desired action:

uint16_t queue_indices[] = {10, 11, 12, 13, 14, 15};
struct rte_flow_action_queue queue = {.index = queue_indices};
struct rte_flow_action action[]={
    [0]={.type = RTE_FLOW_ACTION_TYPE_QUEUE,.conf = &queue},
    [1]={.type = RTE_FLOW_ACTION_TYPE_END}
};
Is this action limited to drivers specific?

Example:
I have 40 RX queues I need to match an IP address pattern and the matching packets should direct to 1-10 RX queue indices.


If not, please suggest a way to direct packets that matches a particular pattern to specific multiple RX queues without the use of RSS.
I need the matching packets to distribute evenly to specific RX queues and not the duplicates. I'm using Intel x710 NIC i40e and DPDK 20.11.

Can anyone help on this query.

Thanks,
Raghavan V
