Below are the features that we're planning to submit for the 17.08 release. We'll submit a patch to update the roadmap page with this info.
It would be good if others are also willing to share their plans so that we can build up a complete picture of what's planned for 17.08 and make sure there's no duplication. Generic QoS API: The proposed API is currently being added to the next-tm repository (http://dpdk.org/browse/next/dpdk-next-tm/). In 17.08, implementations of that API will be added for I40E, IXGBE, and the existing software QoS implementation. The API will move from next-tm to the main DPDK repository. Support for IPFIX: An RFC will be created in the next few weeks to support IPFIX (IP Flow Information Export - see https://en.wikipedia.org/wiki/IP_Flow_Information_Export for details) within DPDK. The actual implementation of IPFIX will be the responsibility of the application, but a library will be proposed which will enable an application to implement an IPFIX Observation Point, Metering Process and Exporter Process. Depending on the response to this RFC, we'll consider implementing the IPFIX library for 17.08. GRO (Generic Receive Offload): Generic Receive Offload is a widely used SW-based offloading technique to reduce per-packet processing overhead. It improves performance by reassembling small packets into large ones. A new library will be added to DPDK which will implement GRO. Generic Flow Enhancements: The rte_flow API was added in 17.02 and implemented for IXGBE and I40E. Support will be added for IGB, and enhancements will also be implemented for IXGBE (NVGRE/L2 Tunnel filters). Add Packet Type Recognition to IXGBE Vector PMD: The I40E Vector PMD supports packet type recognition but the IXGBE vPMD doesn't. This is a problem for VPP (https://wiki.fd.io/view/VPP) as they have to add a patch on top of DPDK to implement this. VF Port Reset for IXGBE: This was implemented in 17.05 for I40E (see http://dpdk.org/ml/archives/dev/2017-April/063538.html). Support will be added for IXGBE in 17.08. Cryptodev Multi-Core SW Scheduler: The cryptodev scheduler was first introduced in 17.02 and further enhanced in 17.05. It will be enhanced again in 17.08 to support the ability to use a pool of cores for software crypto. This will allow sufficient capacity to be provisioned for encrypting/decrypting large flows in software. API to Configure Queue Regions for RSS: This provides support for configuration of queue regions for RSS, so that different traffic classes or different packet classification types to be separated into different queues. This will be implemented for I40E.
