Pottermore patronus quiz without signing up• DPDK provides a programming framework for Intel processors and enables faster development of high-speed data packet networking applications. Advanced Traffic Steering Intel® Ethernet Flow Director (Intel® Ethernet FD) is an advanced traffic steering capability. It consists of a large number of flow affinity filters that direct receive Flow director support¶ Advanced filtering support was added to 1300 series VIC firmware starting with version 2.0.13 for C-series UCS servers and version 3.1.2 for UCSM managed blade servers. In order to enable advanced filtering the ‘Advanced filter’ radio button should be enabled via CIMC or UCSM followed by a reboot of the server. The CLI command dma_to_device supported by the DPDK software test application helps verify the ST H2C functionality. The complete flow between the Host SW components and HW components is depicted in below sequence diagram. User needs to configure the queue in ST mode (default) and H2C (Tx) direction If you use dpdk PF and dpdk VF ensure the PF driver is the same version as the VF. Added support for E-tag on X550. ...

This document provides the plan for testing the Flow Director (FDir) feature of the Intel 82599 10GbE Ethernet Controller. FDir allows an application to add filters that identify specific flows (or sets of flows), by examining the VLAN header, IP addresses, port numbers, protocol type (IPv4/IPv6, UDP/TCP, SCTP), or a two-byte tuple within the first 64 bytes of the packet. After the GTPv1 profile is loaded to the Intel® Ethernet Controller, the GTP flow type is defined and encapsulated frame fields (including GTP TEID) can be used for RSS, Flow Director, or Cloud Filters. The NIC has full visibility of all header fields and can perform load distribution to queues based on this improved classification capability. Since we use GLB for both internal and external requests, this flow is for any request into or out of GitHub, basically, and for all services including things like MySQL. After a quick tour of the request flow we’ll get into the two primary components, which is the GLB Director and the GLB Proxy. Start testpmd on host and vm0, host supports flow director and cloud filter, VM supports cloud filter. If test PF flow director, need to add –pkt-filter-mode=perfect on testpmd to enable flow director, set chained port topology mode, add txq/rxq to enable multi-queues. In general, PF’s max queue is 64, VF’s max queue is 4:

testpmd - tests for dpdk pmds ... Set Flow Director hash match reporting mode where mode is none, match (the default) or always.--pkt-filter-size=N. These are the release notes for mlx4 and mlx5 DPDK Poll-Mode Driver (PMD) for ... Flow director VXLAN filter is not supported Will be added in next releases . DPDK Plays Well with Others: Virtualization, Containers, MANO, Ethernet. As DPDK and OVS were designed to “fit in” to the ways customers build and deploy networks and “stand out” with new, differentiating capabilities, network operators are building an open foundation to support new network applications and growth today and in the future.

The ethdev flow director entries for SCTP were changed. This was already included in 2.1 under the CONFIG_RTE_NEXT_ABI #define. The ethdev flow director structure rte_eth_fdir_flow_ext structure was changed. New fields were added to support flow director filtering in VF. Hi Praveen, I do have some review comments on the code. Before that, can you give a brief overview of what is being targeted? My understanding is that the primary objective is to use rte_flow (or flow director) to redirect a specific flow(/SA) to a specific queue.

Port-to-Port switching through rte_flow using logical port id’s. Advance port capabilities management Port representor could be used to define capabilities of the underlying port. e.g. make a VF untrusted so it can change it’s MAC address etc. Limit hardware resources port can use, e.g. number of flow director rules. Aug 08, 2018 · As part of creating the GLB Director, we also created a test environment that supports simple end-to-end packet flow testing of our DPDK application, by leveraging the way DPDK provides an Environment Abstraction Layer (EAL) that allows a physical NIC and a libpcap-based local interface to appear the same from the view of the application. Applications written using DPDK libraries and drivers will be able to use Virtual Function ports where traffic will be directed.The setup of the flow direction uses ethtool NTUPLE/NFC interface, with the Virtual Function as a target.The following example creates two Virtual Functions, each one in a given port, configures the flow director for ...
