Thanks Tom. There is no specific instructions to follow. Flow Director makes use of the 5 tuple src_addr dst_addr protocol src_port dst_port in the See testpmd_flow_director for more details. from traffic generator port 0 in relevant mac address I also modified DPDK 39 s flow_filtering example application and am getting the same reduced throughput of around 41G out of 100G. The Flow Director filters can match the different fields for different type of packet flow type specific input set per flow type and the flexible payload. DPDK is a set of libraries for fast packet processing. 11 introduced more advanced DDP APIs including the ability to report a profile 39 s information without loading a profile to an Intel Ethernet 700 Series network adapter first. User needs to configure the queue in ST mode default and H2C Tx direction Jan 09 2020 DPDK networking drivers are classified in two categories physical for real devices virtual for emulated devices The DPDK ethdev layer exposes APIs in order to use the networking functions of these devices. With OVS DPDK you can enable DVR with netdev datapath but this has poor performance and is not suitable for a production environment. Its main purpose is to forward packets between Ethernet ports on a network interface. iWARP is a highly routable and scalable RDMA implementation.
