23 This section should contain new features added in this release. Sample format:
25 * **Add a title in the past tense with a full stop.**
27 Add a short 1-2 sentence description in the past tense. The description
28 should be enough to allow someone scanning the release notes to understand
31 If the feature adds a lot of sub-features you can use a bullet list like this.
33 * Added feature foo to do something.
34 * Enhanced feature bar to do something else.
36 Refer to the previous release notes for examples.
38 * **Added function to check primary process state.**
40 A new function ``rte_eal_primary_proc_alive()`` has been added
41 to allow the user to detect if a primary process is running.
42 Use cases for this feature include fault detection, and monitoring
43 using secondary processes.
45 * **Enabled bulk allocation of mbufs.**
47 A new function ``rte_pktmbuf_alloc_bulk()`` has been added to allow the user
48 to allocate a bulk of mbufs.
52 Enabled virtio 1.0 support for virtio pmd driver.
54 * **Supported virtio for ARM.**
56 Enabled virtio support for armv7/v8. Tested for arm64.
57 Virtio for arm support VFIO-noiommu mode only.
58 Virtio can work with other non-x86 arch too like powerpc.
60 * **Supported virtio offload in vhost-user.**
62 Add the offload and negotiation of checksum and TSO between vhost-user and
63 vanilla Linux virtio guest.
65 * **Added vhost-user live migration support.**
67 * **Added support for E-tag on X550.**
69 E-tag is defined in 802.1br. Please reference
70 http://www.ieee802.org/1/pages/802.1br.html.
72 This feature is for VF, but the settings are on PF. It means
73 the CLIs should be used on PF, but some of their effects will be shown on VF.
74 The forwarding of E-tag packets based on GRP and E-CID_base will have effect
75 on PF. Theoretically the E-tag packets can be forwarded to any pool/queue.
76 But normally we'd like to forward the packets to the pools/queues belonging
77 to the VFs. And E-tag insertion and stripping will have effect on VFs. When
78 VF receives E-tag packets, it should strip the E-tag. When VF transmits
79 packets, it should insert the E-tag. Both can be offloaded.
81 When we want to use this E-tag support feature, the forwarding should be
82 enabled to forward the packets received by PF to indicated VFs. And insertion
83 and stripping should be enabled for VFs to offload the effort to HW.
85 * Support E-tag offloading of insertion and stripping.
86 * Support Forwarding E-tag packets to pools based on
89 * **Added support for VxLAN & NVGRE checksum off-load on X550.**
91 * Added support for VxLAN & NVGRE RX/TX checksum off-load on
92 X550. RX/TX checksum off-load is provided on both inner and
93 outer IP header and TCP header.
94 * Added functions to support VxLAN port configuration. The
95 default VxLAN port number is 4789 but this can be updated
98 * **Enabled PCI extended tag for i40e.**
100 It enabled extended tag by checking and writing corresponding PCI config
101 space bytes, to boost the performance. In the meanwhile, it deprecated the
102 legacy way via reading/writing sysfile supported by kernel module igb_uio.
104 * **Supported ether type setting of single and double VLAN for i40e**
106 * **Increased number of next hops for LPM IPv4 to 2^24.**
108 The next_hop field is extended from 8 bits to 24 bits for IPv4.
110 * **Added support of SNOW 3G (UEA2 and UIA2) for Intel Quick Assist devices.**
112 Enabled support for SNOW 3G wireless algorithm for Intel Quick Assist devices.
113 Support for cipher only, hash only is also provided
114 along with alg-chaining operations.
116 * **Added SNOW3G SW PMD.**
118 A new Crypto PMD has been added, which provides SNOW 3G UEA2 ciphering
119 and SNOW3G UIA2 hashing.
121 * **Added AES GCM PMD.**
123 Added new Crypto PMD to support AES-GCM authenticated encryption and
124 authenticated decryption in SW.
126 * **Added NULL Crypto PMD**
128 Added new Crypto PMD to support null crypto operations in SW.
133 This section should contain bug fixes added to the relevant sections. Sample format:
135 * **code/section: Fixed issue in the past tense with a full stop.**
137 Add a short 1-2 sentence description of the resolved issue in the past tense.
138 The title should contain the code/lib section like a commit message.
139 Add the entries in alphabetic order in the relevant sections below.
149 * **ethdev: Fixed byte order consistency between fdir flow and mask.**
151 Fixed issue in ethdev library that the structure for setting
152 fdir's mask and flow entry was not consistent in byte ordering.
154 * **aesni_mb: Fixed wrong return value when creating a device.**
156 cryptodev_aesni_mb_init() was returning the device id of the device created,
157 instead of 0 (when success), that rte_eal_vdev_init() expects.
158 This made impossible the creation of more than one aesni_mb device
161 * **qat: Fixed AES GCM decryption.**
163 Allowed AES GCM on the cryptodev API, but in some cases gave invalid results
164 due to incorrect IV setting.
170 * **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.**
172 Fix crc32c hash functions to return a valid crc32c value for data lengths
173 not multiple of 4 bytes.
179 * **examples/vhost: Fixed frequent mbuf allocation failure.**
181 vhost-switch often fails to allocate mbuf when dequeue from vring because it
182 wrongly calculates the number of mbufs needed.
184 * **examples/ipsec-secgw: ipsec security gateway**
186 New application implementing an IPsec Security Gateway.
195 This section should contain new known issues in this release. Sample format:
197 * **Add title in present tense with full stop.**
199 Add a short 1-2 sentence description of the known issue in the present
200 tense. Add information on any known workarounds.
206 This section should contain API changes. Sample format:
208 * Add a short 1-2 sentence description of the API change. Use fixed width
209 quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
211 * The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete``
212 have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and
213 ``rte_eth_dev_udp_tunnel_port_delete``.
215 * The ``outer_mac`` and ``inner_mac`` fields in structure
216 ``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order
217 to keep code's readability.
219 * The fields in ethdev structure ``rte_eth_fdir_masks`` were changed
222 * A parameter ``vlan_type`` has been added to the function
223 ``rte_eth_dev_set_vlan_ether_type``.
225 * The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4
226 while keeping ABI compatibility.
228 * A new ``rte_lpm_config`` structure is used so LPM library will allocate
229 exactly the amount of memory which is necessary to hold application’s rules.
230 The previous ABI is kept for compatibility.
232 * The prototype for the pipeline input port, output port and table action
233 handlers are updated: the pipeline parameter is added,
234 the packets mask parameter has been either removed or made input-only.
240 * Add a short 1-2 sentence description of the ABI change that was announced in
241 the previous releases and made in this release. Use fixed width quotes for
242 ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
244 * The RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased
245 from 8-bit to 16-bit.
247 * The cmdline buffer size has been increase from 256 to 512.
