14. DPDK Release 18.08
14.1. New Features
Added support for Hyper-V netvsc PMD.
The new
netvsc
poll mode driver provides native support for networking on Hyper-V. See the Netvsc poll mode driver NIC driver guide for more details on this new driver.Added Flow API support for CXGBE PMD.
Flow API support has been added to CXGBE Poll Mode Driver to offload flows to Chelsio T5/T6 NICs. Support added for:
Wildcard (LE-TCAM) and Exact (HASH) match filters.
Match items: physical ingress port, IPv4, IPv6, TCP and UDP.
Action items: queue, drop, count, and physical egress port redirect.
Added ixgbe preferred Rx/Tx parameters.
Rather than applications providing explicit Rx and Tx parameters such as queue and burst sizes, they can request that the EAL instead uses preferred values provided by the PMD, falling back to defaults within the EAL if the PMD does not provide any. The provision of such tuned values now includes the ixgbe PMD.
Added descriptor status check support for fm10k.
The
rte_eth_rx_descriptor_status
andrte_eth_tx_descriptor_status
APIs are now supported by fm10K.Updated the enic driver.
Add low cycle count Tx handler for no-offload Tx.
Add low cycle count Rx handler for non-scattered Rx.
Minor performance improvements to scattered Rx handler.
Add handlers to add/delete VxLAN port number.
Add devarg to specify ingress VLAN rewrite mode.
Updated mlx5 driver.
Updated the mlx5 driver including the following changes:
Added port representors support.
Added Flow API support for e-switch rules. Added support for ACTION_PORT_ID, ACTION_DROP, ACTION_OF_POP_VLAN, ACTION_OF_PUSH_VLAN, ACTION_OF_SET_VLAN_VID, ACTION_OF_SET_VLAN_PCP and ITEM_PORT_ID.
Added support for 32-bit compilation.
Added TSO support for the mlx4 driver.
Added TSO support for the mlx4 drivers from MLNX_OFED_4.4 and above.
SoftNIC PMD rework.
The SoftNIC PMD infrastructure has been restructured to use the Packet Framework, which makes it more flexible, modular and easier to add new functionality in the future.
Updated the AESNI MB PMD.
The AESNI MB PMD has been updated with additional support for:
3DES for 8, 16 and 24 byte keys.
Added a new compression PMD using Intel’s QuickAssist (QAT) device family.
Added the new
QAT
compression driver, for compression and decompression operations in software. See the Intel(R) QuickAssist (QAT) Compression Poll Mode Driver compression driver guide for details on this new driver.Updated the ISA-L PMD.
Added support for chained mbufs (input and output).
14.2. API Changes
The path to the runtime config file has changed. The new path is determined as follows:
If DPDK is running as root,
/var/run/dpdk/<prefix>/config
If DPDK is not running as root:
If
$XDG_RUNTIME_DIR
is set,${XDG_RUNTIME_DIR}/dpdk/<prefix>/config
Otherwise,
/tmp/dpdk/<prefix>/config
eal: The function
rte_eal_mbuf_default_mempool_ops
was deprecated and is removed in 18.08. It shall be replaced byrte_mbuf_best_mempool_ops
.mempool: Following functions were deprecated and are removed in 18.08:
rte_mempool_populate_iova_tab
rte_mempool_populate_phys_tab
rte_mempool_populate_phys
(rte_mempool_populate_iova
should be used)rte_mempool_virt2phy
(rte_mempool_virt2iova
should be used)rte_mempool_xmem_create
rte_mempool_xmem_size
rte_mempool_xmem_usage
ethdev: The old offload API is removed:
Rx per-port
rte_eth_conf.rxmode.[bit-fields]
Tx per-queue
rte_eth_txconf.txq_flags
ETH_TXQ_FLAGS_NO*
The transition bits are removed:
rte_eth_conf.rxmode.ignore_offload_bitfield
ETH_TXQ_FLAGS_IGNORE
cryptodev: The following API changes have been made in 18.08:
In struct
struct rte_cryptodev_info
, fieldrte_pci_device *pci_dev
has been replaced with fieldstruct rte_device *device
.Value 0 is accepted in
sym.max_nb_sessions
, meaning that a device supports an unlimited number of sessions.Two new fields of type
uint16_t
have been added:min_mbuf_headroom_req
andmin_mbuf_tailroom_req
. These parameters specify the recommended headroom and tailroom for mbufs to be processed by the PMD.
cryptodev: The following functions were deprecated and are removed in 18.08:
rte_cryptodev_queue_pair_start
rte_cryptodev_queue_pair_stop
rte_cryptodev_queue_pair_attach_sym_session
rte_cryptodev_queue_pair_detach_sym_session
cryptodev: The following functions were deprecated and are replaced by other functions in 18.08:
rte_cryptodev_get_header_session_size
is replaced withrte_cryptodev_sym_get_header_session_size
rte_cryptodev_get_private_session_size
is replaced withrte_cryptodev_sym_get_private_session_size
cryptodev: Feature flag
RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER
is replaced with the following more explicit flags:RTE_CRYPTODEV_FF_IN_PLACE_SGL
RTE_CRYPTODEV_FF_OOP_SGL_IN_SGL_OUT
RTE_CRYPTODEV_FF_OOP_SGL_IN_LB_OUT
RTE_CRYPTODEV_FF_OOP_LB_IN_SGL_OUT
RTE_CRYPTODEV_FF_OOP_LB_IN_LB_OUT
cryptodev: Renamed cryptodev experimental APIs:
Used user_data instead of private_data in following APIs to avoid confusion with the existing session parameter
sess_private_data[]
and related APIs.rte_cryptodev_sym_session_set_private_data()
changed torte_cryptodev_sym_session_set_user_data()
rte_cryptodev_sym_session_get_private_data()
changed torte_cryptodev_sym_session_get_user_data()
compressdev: Feature flag
RTE_COMP_FF_MBUF_SCATTER_GATHER
is replaced with the following more explicit flags:RTE_COMP_FF_OOP_SGL_IN_SGL_OUT
RTE_COMP_FF_OOP_SGL_IN_LB_OUT
RTE_COMP_FF_OOP_LB_IN_SGL_OUT
