26 * **Add a title in the past tense with a full stop.**
28 Add a short 1-2 sentence description in the past tense. The description
29 should be enough to allow someone scanning the release notes to
30 understand the new feature.
32 If the feature adds a lot of sub-features you can use a bullet list like
35 * Added feature foo to do something.
36 * Enhanced feature bar to do something else.

42 =========================================================
44 * **Added support for generic flow API (rte_flow) on igb NIC.**
46 This API provides a generic means to configure hardware to match specific
47 ingress or egress traffic, alter its behavior and query related counters
48 according to any number of user-defined rules.
50 * Generic flow API support for Ethernet, IPv4, UDP, TCP and
51 RAW pattern items with QUEUE actions. There are four
52 type of filter support for this feature on igb.
54 * **Added Generic Flow API support to enic.**
56 Flow API support for outer Ethernet, VLAN, IPv4, IPv6, UDP, TCP, SCTP, VxLAN
57 and inner Ethernet, VLAN, IPv4, IPv6, UDP and TCP pattern items with QUEUE,
58 MARK, FLAG and VOID actions for ingress traffic.

88 * **Reorganized the symmetric crypto operation structure.**
90 The crypto operation (``rte_crypto_sym_op``) has been reorganized as follows:
92 * Removed field ``rte_crypto_sym_op_sess_type``.
93 * Replaced pointer and physical address of IV with offset from the start
94 of the crypto operation.
95 * Moved length and offset of cipher IV to ``rte_crypto_cipher_xform``.
96 * Removed Additional Authentication Data (AAD) length.
97 * Removed digest length.
98 * Removed AAD pointer and physical address from ``auth`` structure.
99 * Added ``aead`` structure, containing parameters for AEAD algorithms.
101 * **Reorganized the crypto operation structure.**
103 The crypto operation (``rte_crypto_op``) has been reorganized as follows:
105 * Added field ``rte_crypto_op_sess_type``.
106 * Enumerations ``rte_crypto_op_status`` and ``rte_crypto_op_type``
107 have been modified to be uint8_t values.
108 * Removed the field ``opaque_data``.
109 * Pointer to ``rte_crypto_sym_op`` has been replaced with a zero length array.
111 * **Reorganized the crypto symmetric session structure.**
113 The crypto symmetric session structure (``rte_cryptodev_sym_session``) has
114 been reorganized as follows:
116 * ``dev_id`` field has been removed.
117 * ``driver_id`` field has been removed.
118 * Mempool pointer ``mp`` has been removed.
119 * Replaced ``private`` marker with array of pointers to private data sessions
120 ``sess_private_data``.
122 * **Updated cryptodev library.**
124 * Added AEAD algorithm specific functions and structures, so it is not
125 necessary to use a combination of cipher and authentication
127 * Added helper functions for crypto device driver identification.
128 * Added support for multi-device sessions, so a single session can be
129 used in multiple drivers.
130 * Added functions to initialize and free individual driver private data
133 * **Updated dpaa2_sec crypto PMD.**
135 Added support for AES-GCM and AES-CTR
137 * **Updated the AESNI MB PMD.**
139 The AESNI MB PMD has been updated with additional support for:
141 * 12-byte IV on AES Counter Mode, apart from the previous 16-byte IV.
143 * **Updated the AES-NI GCM PMD.**
145 The AES-NI GCM PMD was migrated from the ISA-L library to the Multi Buffer
146 library, as the latter library has Scatter Gather List support
147 now. The migration entailed adding additional support for:
151 * **Updated the Cryptodev Scheduler PMD.**
153 Added a multicore based distribution mode, which distributes the enqueued
154 crypto operations among several slaves, running on different logical cores.
156 * **Added dpdk-test-eventdev test application.**
158 The dpdk-test-eventdev tool is a Data Plane Development Kit (DPDK) application
159 that allows exercising various eventdev use cases.
160 This application has a generic framework to add new eventdev based test cases
161 to verify functionality and measure the performance parameters of DPDK

244 for the device anymore.
245 * ``rte_cryptodev_queue_pair_attach_sym_session()`` and
246 ``rte_cryptodev_queue_pair_dettach_sym_session()`` functions require
