42 =========================================================
44 * **Bumped minimal x86 ISA to SSE4.2.**
46 Starting with version 17.08, DPDK requires SSE4.2 to run on x86.
47 Previous versions required SSE3.
49 * **Added Service Core functionality.**
51 The service core functionality added to EAL allows DPDK to run services such
52 as SW PMDs on lcores without the application manually running them. The
53 service core infrastructure allows flexibility of running multiple services
54 on the same service lcore, and provides the application with powerful APIs to
55 configure the mapping from service lcores to services.
57 * **Added Generic Receive Offload API.**
59 Generic Receive Offload (GRO) API supports to reassemble TCP/IPv4
60 packets. GRO API assumes all inputted packets are with correct
61 checksums. GRO API doesn't update checksums for merged packets. If
62 inputted packets are IP fragmented, GRO API assumes they are complete
63 packets (i.e. with L4 headers).
65 * **Added support for generic flow API (rte_flow) on igb NIC.**
67 This API provides a generic means to configure hardware to match specific
68 ingress or egress traffic, alter its behavior and query related counters
69 according to any number of user-defined rules.
71 * Generic flow API support for Ethernet, IPv4, UDP, TCP and
72 RAW pattern items with QUEUE actions. There are four
73 type of filter support for this feature on igb.
75 * **Added Generic Flow API support to enic.**
77 Flow API support for outer Ethernet, VLAN, IPv4, IPv6, UDP, TCP, SCTP, VxLAN
78 and inner Ethernet, VLAN, IPv4, IPv6, UDP and TCP pattern items with QUEUE,
79 MARK, FLAG and VOID actions for ingress traffic.
81 * **Added support for Chelsio T6 family of adapters**
83 CXGBE PMD updated to run Chelsio T6 family of adapters.

132 * Replaced pointer and physical address of IV with offset from the start
133 of the crypto operation.
134 * Moved length and offset of cipher IV to ``rte_crypto_cipher_xform``.

136 * Removed digest length.
137 * Removed AAD pointer and physical address from ``auth`` structure.
138 * Added ``aead`` structure, containing parameters for AEAD algorithms.
140 * **Reorganized the crypto operation structure.**

164 necessary to use a combination of cipher and authentication
166 * Added helper functions for crypto device driver identification.
167 * Added support for multi-device sessions, so a single session can be
168 used in multiple drivers.
169 * Added functions to initialize and free individual driver private data

180 * 12-byte IV on AES Counter Mode, apart from the previous 16-byte IV.
182 * **Updated the AES-NI GCM PMD.**
184 The AES-NI GCM PMD was migrated from the ISA-L library to the Multi Buffer
185 library, as the latter library has Scatter Gather List support
186 now. The migration entailed adding additional support for:
190 * **Updated the Cryptodev Scheduler PMD.**
192 Added a multicore based distribution mode, which distributes the enqueued
193 crypto operations among several slaves, running on different logical cores.
195 * **Added NXP DPAA2 Eventdev PMD.**
197 Added the new dpaa2 eventdev driver for NXP DPAA2 devices. See the
198 "Event Device Drivers" document for more details on this new driver.

202 The dpdk-test-eventdev tool is a Data Plane Development Kit (DPDK) application
203 that allows exercising various eventdev use cases.
204 This application has a generic framework to add new eventdev based test cases
205 to verify functionality and measure the performance parameters of DPDK
