This can be used by + applications to have its threads known of DPDK without suffering from the + non-EAL previous limitations in terms of performance. + +* **rte_*mb APIs are updated to use DMB instruction for ARMv8.** + + ARMv8 memory model has been strengthened to require other-multi-copy + atomicity. This allows for using DMB instruction instead of DSB for IO + barriers. rte_*mb APIs, for ARMv8 platforms, are changed to use DMB + instruction to reflect this. + +* **Added support for RTS and HTS modes into mempool ring driver.** + + Added ability to select new ring synchronisation modes: + ``relaxed tail sync (ring_mt_rts)`` and ``head/tail sync (ring_mt_hts)`` + via mempool ops API. + +* **Added the support for vfio-pci new VF token interface.** + + From Linux 5.7, vfio-pci supports to bind both SR-IOV PF and the created VFs, + it uses a shared VF token (UUID) to represent the collaboration between PF + and VFs. Update DPDK PCI driver to gain the access to the PF and VFs devices + by appending the VF token parameter. + +* **Added the RegEx Library, a generic RegEx service library.** + + Added the RegEx library which provides an API for offload of regular + expressions search operations to hardware or software accelerator devices. + + Added Mellanox RegEx PMD, allowing to offload RegEx searches. + +* **Added eCPRI protocol support in rte_flow.** + + The ``ECPRI`` item has been added to support eCPRI packet offloading for + 5G network. + +* **Introduced send packet scheduling on the timestamps.** + + Added the new mbuf dynamic field and flag to provide timestamp on what packet + transmitting can be synchronized. The device Tx offload flag is added to + indicate the PMD supports send scheduling. + * **Updated PCAP driver.** Updated PCAP driver with new features and improvements, including: * Support software Tx nanosecond timestamps precision. -* **Updated Mellanox mlx5 driver.** +* **Updated Broadcom bnxt driver.** + + Updated the Broadcom bnxt driver with new features and improvements, including: + + * Added support for VF representors. + * Added support for multiple devices. + * Added support for new resource manager API. + * Added support for VXLAN encap/decap. + * Added support for rte_flow_query for COUNT action. + * Added support for rx_burst_mode_get and tx_burst_mode_get. + * Added vector mode support for ARM CPUs. + * Added support for VLAN push and pop actions. + * Added support for NAT action items. + +* **Updated Cisco enic driver.** + + * Added support for VLAN push and pop flow actions. + +* **Updated Hisilicon hns3 driver.** + + * Added support for 200G speed rate. + * Added support for copper media type. + * Added support for keeping CRC. + * Added support for LRO. + * Added support for setting VF PVID by PF driver. + +* **Updated Mellanox mlx5 net driver and common layer.** Updated Mellanox mlx5 driver with new features and improvements, including: + * Added mlx5 PCI layer to share a PCI device among multiple PMDs. * Added new PMD devarg ``reclaim_mem_mode``. * Added new devarg ``lacp_by_user``. + * Added support for eCPRI protocol offloading. * **Added vDPA device APIs to query virtio queue statistics.** @@ -90,6 +162,62 @@ New Features Updated the Intel ice driver with new features and improvements, including: * Added support for DCF datapath configuration. + * Added support for more PPPoE packet type for switch filter. + +* **Updated Intel i40e driver.** + + Updated i40e PMD with new features and improvements, including: + + * Supported cloud filter for IPv4/6_TCP/UDP/SCTP with SRC port only or DST port only. + * Re-implemented get_fdir_info and get_fdir_stat in private API. + * Re-implemented set_gre_key_len in private API. + * Added support for flow query RSS. + +* **Updated the Intel ixgbe driver.** + + Updated the Intel ixgbe driver with new features and improvements, including: + + * Re-implemented get_fdir_info and get_fdir_stat in private API. + +* **Updated NXP dpaa ethdev PMD.** + + Updated the NXP dpaa ethdev with new features and improvements, including: + + * Added support for link status and interrupt + * Added support to use datapath APIs from non-EAL pthread + +* **Updated NXP dpaa2 ethdev PMD.** + + Updated the NXP dpaa2 ethdev with new features and improvements, including: + + * Added support to use datapath APIs from non-EAL pthread + * Added support for dynamic flow management + +* **Added DOCSIS protocol to rte_security.** + + Added support for combined crypto and CRC operations for the DOCSIS protocol + to ``rte_security`` API. + +* **Updated the AESNI MB crypto PMD.** + + Added support for lookaside protocol offload for DOCSIS through the + ``rte_security`` API. + +* **Updated the QuickAssist Technology (QAT) PMD.** + + * Added support for lookaside protocol offload in QAT crypto PMD + for DOCSIS through the ``rte_security`` API. + * Added Chacha20-Poly1305 AEAD algorithm in QAT crypto PMD. + * Improved handling of multi process in QAT crypto and compression PMDs. + * Added support for Intel GEN2 QuickAssist device 200xx + (PF Did 0x18ee, VF Did 0x18ef). + +* **Updated the OCTEON TX2 crypto PMD.** + + * Added Chacha20-Poly1305 AEAD algorithm support in OCTEON TX2 crypto PMD. + + * Updated the OCTEON TX2 crypto PMD to support ``rte_security`` lookaside + protocol offload for IPsec. * **Added support for BPF_ABS/BPF_IND load instructions.** @@ -98,6 +226,12 @@ New Features which are used to access packet data in a safe manner.
