That allows user to inspect + objects in the ring without removing them from it (aka MT safe peek). + +* **Updated Amazon ena driver.** + + Updated ena PMD with new features and improvements, including: + + * Added support for large LLQ (Low-latency queue) headers. + * Added Tx drops as new extended driver statistic. + * Added support for accelerated LLQ mode. + * Handling of the 0 length descriptors on the Rx path. + +* **Updated Intel i40e driver.** + + Updated i40e PMD with new features and improvements, including: + + * Enable MAC address as FDIR input set for ipv4-other, ipv4-udp and ipv4-tcp. + * Added support for RSS using L3/L4 source/destination only. + * Added support for setting hash function in rte flow. + +* **Updated the Intel iavf driver.** + + Update the Intel iavf driver with new features and improvements, including: + + * Added generic filter support. + +* **Updated the Intel ice driver.** + + Updated the Intel ice driver with new features and improvements, including: + + * Added support for DCF (Device Config Function) feature. + * Added switch filter support for intel DCF. + +* **Updated Marvell OCTEON TX2 ethdev driver.** + + Updated Marvell OCTEON TX2 ethdev driver with traffic manager support with + below features. + + * Hierarchial Scheduling with DWRR and SP. + * Single rate - Two color, Two rate - Three color shaping. + +* **Updated Mellanox mlx5 driver.** + + Updated Mellanox mlx5 driver with new features and improvements, including: + + * Added support for matching on IPv4 Time To Live and IPv6 Hop Limit. + * Added support for creating Relaxed Ordering Memory Regions. + +* **Updated the AESNI MB crypto PMD.** + + * Added support for intel-ipsec-mb version 0.54. + * Updated the AESNI MB PMD with AES-256 DOCSIS algorithm. + * Added support for synchronous Crypto burst API. + +* **Updated the AESNI GCM crypto PMD.** + + * Added support for intel-ipsec-mb version 0.54. + +* **Added a new driver for Intel Foxville I225 devices.** + + Added the new ``igc`` net driver for Intel Foxville I225 devices. See the + :doc:`../nics/igc` NIC guide for more details on this new driver. + +* **Added handling of mixed crypto algorithms in QAT PMD for GEN2.** + + Enabled handling of mixed algorithms in encrypted digest hash-cipher + (generation) and cipher-hash (verification) requests in QAT PMD + when running on GEN2 QAT hardware with particular firmware versions + (GEN3 support was added in DPDK 20.02). + +* **Added plain SHA-1,224,256,384,512 support to QAT PMD.** + + Added support for plain SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 hashes + to QAT PMD. + +* **Added QAT intermediate buffer too small handling in QAT compression PMD.** + + Added a special way of buffer handling when internal QAT intermediate buffer + is too small for Huffman dynamic compression operation. Instead of falling + back to fixed compression, the operation is now split into multiple smaller + dynamic compression requests (possible to execute on QAT) and their results + are then combined and copied into the output buffer. This is not possible if + any checksum calculation was requested - in such case the code falls back to + fixed compression as before. + +* **Updated the turbo_sw bbdev PMD.** + + Supported large size code blocks which does not fit in one mbuf segment. + +* **Added Intel FPGA_5GNR_FEC bbdev PMD.** + + Added a new ``fpga_5gnr_fec`` bbdev driver for the Intel\ |reg| FPGA PAC + (Programmable Acceleration Card) N3000. See the + :doc:`../bbdevs/fpga_5gnr_fec` BBDEV guide for more details on this new driver. + +* **Updated ipsec-secgw sample application with following features.** + + * Updated ipsec-secgw application to add event based packet processing. + The worker thread(s) would receive events and submit them back to the + event device after the processing. This way, multicore scaling and HW + assisted scheduling is achieved by making use of the event device + capabilities. The event mode currently supports only inline IPsec + protocol offload. + + * Updated ipsec-secgw application to support key sizes for AES-192-CBC, + AES-192-GCM, AES-256-GCM algorithms. + + * Added IPsec inbound load-distribution support for ipsec-secgw application + using NIC load distribution feature(Flow Director). + Removed Items -------------
