charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi Team, Is there any possible way to create multiple RSS flows to distribute packet= s to set of queues when a particular Ip pattern matches. For e.g., I have 40 RX queues setup, Flow 1: Match a particular IP pattern and distribute it to specified RX que= ues set (0 - 29) Flow 2: Match a particular IP pattern and distribute it to specified RX que= ues set (30 - 39) Is the below code snippet possible? Also is it possible to use symmetric to= eplitz hash and ETH_RSS_L3_SRC_ONLY | ETH_RSS_L3_DST_ONLY and let me know = any other config should be included. uint16_t queue_indices[] =3D {0,...29}; uint16_t queue_indices2[] =3D {30,..39}; action_rss1 =3D (struct rte_flow_action_rss){ .types =3D rss_conf.rss_hf, .key_len =3D rss_conf.rss_key_len, .queue_num =3D 30, .key =3D rss_key, .queue =3D queue_indices, }; action_rss2 =3D (struct rte_flow_action_rss){ .types =3D rss_conf.rss_hf, .key_len =3D rss_conf.rss_key_len, .queue_num =3D 10, .key =3D rss_key, .queue =3D queue_indices2, }; struct rte_flow_item pattern[] =3D { [0]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_ETH, }, [1]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_IPV4, .spec =3D &ipv4_spec, .mask =3D &ipv4_mask, }, [2]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_UDP, }, [3]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_END, } }; struct rte_flow_item pattern2[] =3D { [0]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_ETH, }, [1]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_IPV4, .spec =3D &ipv4_spec2, .mask =3D &ipv4_mask2, }, [2]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_UDP, }, [3]=3D{ .type =3D RTE_FLOW_ITEM_TYPE_END, } }; rte_flow_validate(bond_port, &attr, pattern, action_rss1, &error); rte_flow_create(bond_port, &attr, pattern, action_rss1, &error); rte_flow_validate(bond_port, &attr, pattern2, action_rss2, &error); rte_flow_create(bond_port, &attr, pattern2, action_rss2, &error); Pls let me know any other approach will match my requirement.

Hi T= eam,

Is there any possible way to create= multiple RSS flows to distribute packets to set of queues when a particula= r Ip pattern matches.
For e.g.,
I have 40 RX queues setup,
Flow 1: Match a particular IP pattern and distribute it to specified RX que= ues set (0 - 29)
Flow 2: Match a particular IP pattern and distribute it to specified RX que= ues set (30 - 39)

Is the below code snippet possible? Also i= s it possible to use symmetric toeplitz  hash and ETH_RSS_L3_SRC_ONLY = | ETH_RSS_L3_DST_ONLY and let me know any other config should be included.<= o:p>
