Hello, We are planning to utilize the rte_flow (generic flow interface) introduced in DPDK 16.11. It provides, among other things, a flow action type called RTE_FLOW_ACTION_TYPE_MARK that attaches an arbitrary 32-bit integer value for packets matching the flow director rules and sets PKT_RX_FDIR_ID flag (flow director ID reported if FDIR match). Would like to understand the following: 1) Are the OVS changes in place to be able to make use of this driver returned ³hint² (or flow-id) in the data path for lookups? If so, can you please provide code pointer? 2) Is that 32-bit tag/flow_id meant to be used for megaflow cache only? In the existing implementation, it seems NIC computed RSS hash is used for EMC only.
Thanks, Harish _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
