<br>
You want RTE_FLOW_ACTION_TYPE_RSS<br>
<br>
uint16_t queue_indices[] = {10, 11, 12, 13, 14, 15};<br>
struct rte_flow_action_rss rss = {<br>
.types = RTE_ETH_RSS_UDP | RTE_ETH_RSS_TCP,<br>
.queue_num = RTE_DIM(queue_indicies),<br>
.queue = queue_indicies,<br>
};<br>
<br>
struct rte_flow_action action[]={<br>
[0]={.type = RTE_FLOW_ACTION_TYPE_RSS,.conf = &rss},<br>
[1]={.type = RTE_FLOW_ACTION_TYPE_END}<br>
};<br>
<br>
> Is this action limited to drivers specific?<br>
Yes, drivers implement only what hardware can support.<br>
