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 * **Added new X550EM_a devices.**
100 Added new X550EM_a devices and their mac types, X550EM_a and X550EM_a_vf.
101 Updated the code to use the new devices and mac types.
103 * **Added x550em_x V2 device support.**
105 Only x550em_x V1 was supported before. Now V2 is supported.
106 A mask for V1 and V2 is defined and used to support both.
108 * **Added sw-firmware sync on X550EM_a.**
110 Added support for sw-firmware sync for resource sharing.
111 Use the PHY token, shared between sw-fw for PHY access on X550EM_a.
113 * **Enabled PCI extended tag for i40e.**
115 It enabled extended tag by checking and writing corresponding PCI config
116 space bytes, to boost the performance. In the meanwhile, it deprecated the
117 legacy way via reading/writing sysfile supported by kernel module igb_uio.
119 * **Supported ether type setting of single and double VLAN for i40e**
121 * **Increased number of next hops for LPM IPv4 to 2^24.**
123 The next_hop field is extended from 8 bits to 24 bits for IPv4.
125 * **Added support of SNOW 3G (UEA2 and UIA2) for Intel Quick Assist devices.**
127 Enabled support for SNOW 3G wireless algorithm for Intel Quick Assist devices.
128 Support for cipher only, hash only is also provided
129 along with alg-chaining operations.
131 * **Added SNOW3G SW PMD.**
133 A new Crypto PMD has been added, which provides SNOW 3G UEA2 ciphering
134 and SNOW3G UIA2 hashing.
136 * **Added AES GCM PMD.**
138 Added new Crypto PMD to support AES-GCM authenticated encryption and
139 authenticated decryption in SW.
141 * **Added NULL Crypto PMD**
143 Added new Crypto PMD to support null crypto operations in SW.
145 * **Added IPsec security gateway example.**
147 New application implementing an IPsec Security Gateway.
153 This section should contain bug fixes added to the relevant sections. Sample format:
155 * **code/section: Fixed issue in the past tense with a full stop.**
157 Add a short 1-2 sentence description of the resolved issue in the past tense.
158 The title should contain the code/lib section like a commit message.
159 Add the entries in alphabetic order in the relevant sections below.
169 * **ethdev: Fixed byte order consistency between fdir flow and mask.**
171 Fixed issue in ethdev library that the structure for setting
172 fdir's mask and flow entry was not consistent in byte ordering.
174 * **cxgbe: Fixed crash due to incorrect size allocated for RSS table.**
176 Fixed a segfault that occurs when accessing part of port 0's RSS
177 table that gets overwritten by subsequent port 1's part of the RSS
178 table due to incorrect size allocated for each entry in the table.
180 * **cxgbe: Fixed setting wrong device MTU.**
182 Fixed an incorrect device MTU being set due to ethernet header and
183 CRC lengths being added twice.
185 * **ixgbe: Fixed zeroed VF mac address.**
187 Resolved an issue where VF mac address is zeroed out in cases where the VF
188 driver is loaded while the PF interface is down.
189 The solution is to only set it when we get an ACK from the PF.
191 * **ixgbe: Fixed setting flow director flag twice.**
193 Resolved an issue where packets were being dropped when switching to perfect
196 * **ixgbe: Set MDIO speed after MAC reset.**
198 The MDIO clock speed must be reconfigured after the MAC reset. The MDIO clock
199 speed becomes invalid, therefore the driver reads invalid PHY register values.
200 The driver now set the MDIO clock speed prior to initializing PHY ops and
201 again after the MAC reset.
203 * **aesni_mb: Fixed wrong return value when creating a device.**
205 cryptodev_aesni_mb_init() was returning the device id of the device created,
206 instead of 0 (when success), that rte_eal_vdev_init() expects.
207 This made impossible the creation of more than one aesni_mb device
210 * **qat: Fixed AES GCM decryption.**
212 Allowed AES GCM on the cryptodev API, but in some cases gave invalid results
213 due to incorrect IV setting.
219 * **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.**
221 Fix crc32c hash functions to return a valid crc32c value for data lengths
222 not multiple of 4 bytes.
228 * **examples/vhost: Fixed frequent mbuf allocation failure.**
230 vhost-switch often fails to allocate mbuf when dequeue from vring because it
231 wrongly calculates the number of mbufs needed.
241 This section should contain new known issues in this release. Sample format:
243 * **Add title in present tense with full stop.**
245 Add a short 1-2 sentence description of the known issue in the present
246 tense. Add information on any known workarounds.
252 This section should contain API changes. Sample format:
254 * Add a short 1-2 sentence description of the API change. Use fixed width
255 quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
257 * The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete``
258 have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and
259 ``rte_eth_dev_udp_tunnel_port_delete``.
261 * The ``outer_mac`` and ``inner_mac`` fields in structure
262 ``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order
263 to keep code's readability.
265 * The fields in ethdev structure ``rte_eth_fdir_masks`` were changed
268 * A parameter ``vlan_type`` has been added to the function
269 ``rte_eth_dev_set_vlan_ether_type``.
271 * The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4
272 while keeping ABI compatibility.
274 * A new ``rte_lpm_config`` structure is used so LPM library will allocate
275 exactly the amount of memory which is necessary to hold application’s rules.
276 The previous ABI is kept for compatibility.
278 * The prototype for the pipeline input port, output port and table action
279 handlers are updated: the pipeline parameter is added,
280 the packets mask parameter has been either removed or made input-only.
286 * Add a short 1-2 sentence description of the ABI change that was announced in
287 the previous releases and made in this release. Use fixed width quotes for
288 ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
290 * The RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased
291 from 8-bit to 16-bit.
293 * The cmdline buffer size has been increase from 256 to 512.
