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