3. DPDK Release 20.11

3.1. New Features

Added write combining store APIs.

Added rte_write32_wc and rte_write32_wc_relaxed APIs that enable write combining stores (depending on architecture). The functions are provided as a generic stub and x86 specific implementation.
Added prefetch with intention to write APIs.

Added new prefetch function variants e.g. rte_prefetch0_write, which allow the programmer to prefetch a cache line and also indicate the intention to write.
Added the rte_cldemote API.

Added a hardware hint CLDEMOTE, which is similar to prefetch in reverse. CLDEMOTE moves the cache line to the more remote cache, where it expects sharing to be efficient. Moving the cache line to a level more distant from the processor helps to accelerate core-to-core communication. This API is specific to x86 and implemented as a stub for other architectures.
Added support for limiting maximum SIMD bitwidth.

Added a new EAL config setting max_simd_bitwidth to limit the vector path selection at runtime. This value can be set by apps using the rte_vect_set_max_simd_bitwidth function, or by the user with EAL flag --force-max-simd-bitwidth.
Added zero copy APIs for rte_ring.

For rings with producer/consumer in RTE_RING_SYNC_ST, RTE_RING_SYNC_MT_HTS modes, these APIs split enqueue/dequeue operation into three phases (enqueue/dequeue start, copy data to/from ring, enqueue/dequeue finish). Along with the advantages of the peek APIs, these provide the ability to copy the data to the ring memory directly without the need for temporary storage.
Updated CRC modules of the net library.
- Added runtime selection of the optimal architecture-specific CRC path.
- Added optimized implementations of CRC32-Ethernet and CRC16-CCITT using the AVX512 and VPCLMULQDQ instruction sets.
Introduced extended buffer description for receiving.

Added the extended Rx buffer description for Rx queue setup routine providing the individual settings for each Rx segment with maximal size, buffer offset and memory pool to allocate data buffers from.
Added the FEC API, for a generic FEC query and config.

Added the FEC API which provides functions for query FEC capabilities and current FEC mode from device. An API for configuring FEC mode is also provided.
Added thread safety to rte_flow functions.

Added the RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE device flag to indicate whether a PMD supports thread safe operations. If the PMD doesn’t set the flag, the rte_flow API level functions will protect the flow operations with a mutex.
Added flow-based traffic sampling support.

Added a new action RTE_FLOW_ACTION_TYPE_SAMPLE that will sample the incoming traffic and send a duplicated traffic with the specified ratio to the application, while the original packet will continue to the target destination.

The packets sampling is ‘1/ratio’. A ratio value set to 1 means that the packets will be completely mirrored. The sample packet can be assigned with a different set of actions than the original packet.
Added support of shared action in flow API.

Added shared action support to use single flow actions in multiple flow rules. An update to the shared action configuration alters the behavior of all flow rules using it.
- Added a new action: RTE_FLOW_ACTION_TYPE_SHARED to use shared action as a flow action.

Added support to flow rules to allow private PMD items/actions.
- Flow rule verification has been updated to accept private PMD items and actions.
Added a generic API to offload tunneled traffic and restore missed packets.
- Added a new hardware independent helper to the flow API that offloads tunneled traffic and restores missed packets.
Updated the ethdev library to support hairpin between two ports.

New APIs have been introduced to support binding / unbinding of 2 ports in a hairpin configuration. The hairpin Tx part flow rules can be inserted explicitly. A new API has been added to get the hairpin peer ports list.

Removed TEP termination sample application.
Removed the deprecated dpdk-setup.sh script.

3.3. API Changes

build macros: The macros defining RTE_MACHINE_CPUFLAG_* have been removed. The information provided by these macros is now available through standard compiler macros.
eal: Replaced the function rte_get_master_lcore() with rte_get_main_lcore(). The old function is deprecated.

The iterator for worker lcores is also changed: RTE_LCORE_FOREACH_SLAVE is replaced with RTE_LCORE_FOREACH_WORKER.
eal: The definitions related to including and excluding devices have been changed from blacklist/whitelist to block/allow list. There are compatibility macros and command line mapping to accept the old values but applications and scripts are strongly encouraged to migrate to the new names.
eal: The rte_logs struct and global symbol was made private and is no longer part of the API.
eal: Made the rte_dev_event structure private to the EAL as no public API used it.
eal: rte_cio_rmb() and rte_cio_wmb() were deprecated since 20.08 and are removed in this release.
mem: Removed the unioned field phys_addr from the structures rte_memseg and rte_memzone. The field iova remains from the old unions.
mempool: Removed the unioned fields phys_addr and physaddr from the structures rte_mempool_memhdr and rte_mempool_objhdr. The field iova remains from the old unions. The flag name MEMPOOL_F_NO_PHYS_CONTIG is removed, while the aliased flag MEMPOOL_F_NO_IOVA_CONTIG is kept.
mbuf: Removed the functions rte_mbuf_data_dma_addr* and the macros rte_pktmbuf_mtophys*. The same functionality is still available with the functions and macros having iova in their names instead of dma_addr or mtophys.
mbuf: Removed the unioned field buf_physaddr from rte_mbuf. The field buf_iova remains from the old union.
mbuf: Removed the unioned field refcnt_atomic from the structures rte_mbuf and rte_mbuf_ext_shared_info. The field refcnt remains from the old unions.
mbuf: Removed the unioned fields userdata and udata64 from the structure rte_mbuf. It is replaced with dynamic fields.
mbuf: Removed the field seqn from the structure rte_mbuf. It is replaced with dynamic fields.
mbuf: Removed the field timestamp from the structure rte_mbuf. It is replaced with the dynamic field RTE_MBUF_DYNFIELD_TIMESTAMP_NAME which was previously used only for Tx.
pci: Removed the rte_kernel_driver enum defined in rte_dev.h and replaced with a private enum in the PCI subsystem.
pci: Removed the PCI resources map API from the public API (pci_map_resource and pci_unmap_resource) and moved it to the PCI bus driver along with the PCI resources lists and associated structures (pci_map, pci_msix_table, mapped_pci_resource and mapped_pci_res_list).
ethdev: Removed the kdrv field in the ethdev rte_eth_dev_data structure as it gave no useful abstracted information to the applications.
ethdev: rte_eth_rx_descriptor_done() API has been deprecated.
ethdev: Renamed basic statistics per queue. An underscore is inserted between the queue number and the rest of the xstat name:
- rx_qN* -> rx_qN_*
- tx_qN* -> tx_qN_*
ethdev: Added capability to query age flow action.
ethdev: Changed rte_eth_dev_stop return value from void to int to provide a way to report various error conditions.
ethdev: Added int return type to rte_eth_dev_close().
ethdev: Renamed internal functions:
- _rte_eth_dev_callback_process() -> rte_eth_dev_callback_process()
- _rte_eth_dev_reset -> rte_eth_dev_internal_reset()
ethdev: Modified field type of base and nb_queue in struct rte_eth_dcb_tc_queue_mapping from uint8_t to uint16_t. As the data of uint8_t will be truncated when queue number in a TC is greater than 256.
ethdev: Removed the legacy filter API, including rte_eth_dev_filter_supported() and rte_eth_dev_filter_ctrl().
ethdev: Removed the legacy L2 tunnel configuration API, including rte_eth_dev_l2_tunnel_eth_type_conf() and rte_eth_dev_l2_tunnel_offload_set()..
vhost: Moved vDPA APIs from experimental to stable.
vhost: Add a new function rte_vhost_crypto_driver_start to be called instead of rte_vhost_driver_start by crypto applications.
cryptodev: The structure rte_crypto_sym_vec is updated to support both cpu_crypto synchronous operations and asynchronous raw data-path APIs.
cryptodev: RTE_CRYPTO_AEAD_LIST_END from enum rte_crypto_aead_algorithm, RTE_CRYPTO_CIPHER_LIST_END from enum rte_crypto_cipher_algorithm and RTE_CRYPTO_AUTH_LIST_END from enum rte_crypto_auth_algorithm are removed to avoid future ABI breakage while adding new algorithms.
scheduler: Renamed functions rte_cryptodev_scheduler_slave_attach, rte_cryptodev_scheduler_slave_detach and rte_cryptodev_scheduler_slaves_get to rte_cryptodev_scheduler_worker_attach, rte_cryptodev_scheduler_worker_detach and rte_cryptodev_scheduler_workers_get accordingly.
scheduler: Renamed the configuration value RTE_CRYPTODEV_SCHEDULER_MAX_NB_SLAVES to RTE_CRYPTODEV_SCHEDULER_MAX_NB_WORKERS.
security: The hfn_ovrd field in rte_security_pdcp_xform is changed from uint32_t to uint8_t so that a new field sdap_enabled can be added to support SDAP.
security: The API rte_security_session_create is updated to take two mempool objects: one for session and other for session private data. So the application need to create two mempools and get the size of session private data using API rte_security_session_get_size for private session mempool.
ipsec: RTE_SATP_LOG2_NUM has been dropped from enum and subsequently moved rte_ipsec lib from experimental to stable.
baseband/fpga_lte_fec: Renamed function fpga_lte_fec_configure to rte_fpga_lte_fec_configure and structure fpga_lte_fec_conf to rte_fpga_lte_fec_conf.
baseband/fpga_5gnr_fec: Renamed function fpga_5gnr_fec_configure to rte_fpga_5gnr_fec_configure and structure fpga_5gnr_fec_conf to rte_fpga_5gnr_fec_conf.
rawdev: Added a structure size parameter to the functions rte_rawdev_queue_setup(), rte_rawdev_queue_conf_get(), rte_rawdev_info_get() and rte_rawdev_configure(), allowing limited driver type-checking and ABI compatibility.
rawdev: Changed the return type of the function rte_dev_info_get() and the function rte_rawdev_queue_conf_get() from void to int allowing the return of error codes from drivers.
rawdev: The running of a drivers selftest() function can now be done using the rawdev_autotest command in the dpdk-test binary. This command now calls the self-test function for each rawdev found on the system, and does not require a specific command per device type. Following this change, the ioat_rawdev_autotest command has been removed as no longer needed.
raw/ioat: As noted above, the rte_ioat_do_copies() and rte_ioat_completed_copies() functions have been renamed to rte_ioat_perform_ops() and rte_ioat_completed_ops() respectively.
stack: the experimental tag has been dropped from the stack library, and its interfaces are considered stable as of DPDK 20.11.
bpf: RTE_BPF_XTYPE_NUM has been dropped from rte_bpf_xtype.
gso: Changed rte_gso_segment behaviour and return value:
- pkt is not saved to pkts_out[0] if not GSOed.
- Return 0 instead of 1 for the above case.
- pkt is not freed, no matter whether it is GSOed, leaving to the caller.
acl: RTE_ACL_CLASSIFY_NUM enum value has been removed. This enum value was not used inside DPDK, while it prevented the addition of new classify algorithms without causing an ABI breakage.
sched: Added subport_profile_id as an argument to function rte_sched_subport_config.
sched: Removed tb_rate, tc_rate, tc_period and tb_size from struct rte_sched_subport_params.

3.4. ABI Changes
