1. DPDK Release 26.03
1.1. New Features
Added custom memory allocation hooks in ACL library.
Added a hook API mechanism allowing applications to provide their own allocation and free functions for ACL runtime memory.
Updated AMD axgbe ethernet driver.
Added support for V4000 Krackan2e.
Updated CESNET nfb ethernet driver.
The timestamp value has been updated to make it usable.
Updated Google Virtual Ethernet (gve) driver.
Added application-initiated device reset.
Updated Intel iavf driver.
Added support for pre and post VF reset callbacks.
Updated Marvell cnxk net driver.
Added out-of-place support for CN20K SoC.
Updated ZTE zxdh ethernet driver.
Added support for modifying queue depth.
Optimized queue allocation resources.
Added support for setting link speed and getting auto-negotiation status.
Added support for secondary processes.
Added support for GENEVE TSO and tunnel outer UDP Rx checksum.
Added 256-NEA/NCA/NIA algorithms in cryptodev library.
Added support for following wireless algorithms: * NEA4, NIA4, NCA4: Snow 5G confidentiality, integrity and AEAD modes. * NEA5, NIA5, NCA5: AES 256 confidentiality, integrity and AEAD modes. * NEA6, NIA6, NCA6: ZUC 256 confidentiality, integrity and AEAD modes.
Updated openssl crypto driver.
Added support for AES-XTS cipher algorithm.
Added support for SHAKE-128 and SHAKE-256 authentication algorithms.
Added Ctrl+L support to cmdline library.
Added handling of the key combination Control+L to clear the screen before redisplaying the prompt.
1.2. Removed Items
Discontinued support for AMD Solarflare SFN7xxx family boards.
7000 series adaptors are out of support in terms of hardware.
Removed the SSE vector paths from some Intel drivers.
The SSE path was not widely used, so it was removed from the i40e, iavf and ice drivers. Each of these drivers have faster vector paths (AVX2 and AVX-512) which have feature parity with the SSE paths, and a fallback scalar path which also has feature parity.
1.3. API Changes
Added additional length checks for name parameter lengths.
Several library functions now have additional name length checks instead of silently truncating.
lpm: name must be less than RTE_LPM_NAMESIZE.
hash: name parameter must be less than RTE_HASH_NAMESIZE.
efd: name must be less than RTE_EFD_NAMESIZE.
tailq: name must be less than RTE_TAILQ_NAMESIZE.
cfgfile: name must be less than CFG_NAME_LEN and value must be less than CFG_VALUE_LEN.
Updated the pcapng library.
The length of comment strings is now validated. Maximum allowable length is 2^16-1 because of pcapng file format.
1.4. ABI Changes
No ABI change that would break compatibility with 25.11.
