12. DPDK Release 19.11
12.1. New Features
Added support for –base-virtaddr EAL option to FreeBSD.
The FreeBSD version of DPDK now also supports setting base virtual address for mapping pages and resources into its address space.
Added Lock-free Stack for aarch64.
Enabled the lock-free stack implementation for aarch64 platforms.
Extended pktmbuf mempool private structure.
rte_pktmbuf_pool_private structure was extended to include flags field for future compatibility. As per 19.11 release this field is reserved and should be set to 0 by the user.
+* Changed mempool allocation behavior.
Changed the mempool allocation behaviour so that objects no longer cross pages by default. Note, this may consume more memory when using small memory pages.
Added support for dynamic fields and flags in mbuf.
This new feature adds the ability to dynamically register some room for a field or a flag in the mbuf structure. This is typically used for specific offload features, where adding a static field or flag in the mbuf is not justified.
Added support for hairpin queues.
On supported NICs, we can now setup hairpin queues which will offload packets from the wire, back to the wire.
Added flow tag in rte_flow.
The
SET_TAG
action andTAG
item have been added to support transient flow tag.Extended metadata support in rte_flow.
Flow metadata has been extended to both Rx and Tx.
Tx metadata can also be set by SET_META action of rte_flow.
Rx metadata is delivered to the host via a dynamic field of
rte_mbuf
withPKT_RX_DYNF_METADATA
.
Added ethdev API to set supported packet types.
Added new API
rte_eth_dev_set_ptypes
which allows an application to inform a PMD about a reduced range of packet types to handle.This scheme will allow PMDs to avoid lookup of internal ptype table on Rx and thereby improve Rx performance if the application wishes to do so.
Added Rx offload flag to enable or disable RSS update.
Added new Rx offload flag
DEV_RX_OFFLOAD_RSS_HASH
which can be used to enable/disable PMDs write torte_mbuf::hash::rss
.PMDs notify the validity of
rte_mbuf::hash:rss
to the application by enablingPKT_RX_RSS_HASH
flag inrte_mbuf::ol_flags
.
Added Rx/Tx packet burst mode “get” API.
Added two new functions
rte_eth_rx_burst_mode_get
andrte_eth_tx_burst_mode_get

that adds event device support to the traditional l2fwd example. It demonstrates usage of poll and event mode IO mechanism under a single application.Added build support for Link Time Optimization.
LTO is an optimization technique used by the compiler to perform whole program analysis and optimization at link time. In order to do that compilers store their internal representation of the source code that the linker uses at the final stage of the compilation process.
See Link Time Optimization for more information:
Added IOVA as VA support for KNI.
Added IOVA = VA support for KNI. KNI can operate in IOVA = VA mode when
iova-mode=va
EAL option is passed to the application or when bus IOVA scheme is selected as RTE_IOVA_VA. This mode only works on Linux Kernel versions 4.10.0 and above.Due to IOVA to KVA address translations, based on the KNI use case there can be a performance impact. For mitigation, forcing IOVA to PA via EAL
--iova-mode=pa
option can be used, IOVA_DC bus iommu scheme can also result in IOVA as PA.
12.2. Removed Items
Removed library-level ABI versions. These have been replaced with a single project-level ABI version for non-experimental libraries and an ABI version of
0
for experimental libraries. Review the ABI Policy and ABI Versioning guides for more information.Removed duplicated set of commands for Rx offload configuration from testpmd:
port config all crc-strip|scatter|rx-cksum|rx-timestamp| hw-vlan|hw-vlan-filter|hw-vlan-strip|hw-vlan-extend on|off
The testpmd command set that can be used instead in order to enable or disable Rx offloading on all Rx queues of a port is:
port config <port_id> rx_offload crc_strip|scatter| ipv4_cksum|udp_cksum|tcp_cksum|timestamp| vlan_strip|vlan_filter|vlan_extend on|off
Removed AF_XDP pmd_zero copy vdev argument. Support is now auto-detected.
The following sample applications have been removed in this release:
Exception Path
L3 Forwarding in a Virtualization Environment
Load Balancer

Quota and Watermark
vhost-scsi
Removed arm64-dpaa2-* build config. arm64-dpaa-* can now build for both dpaa and dpaa2 platforms.
12.3. API Changes
eal: made the
lcore_config
struct and global symbol private.eal: removed the
rte_cpu_check_supported
function, replaced byrte_cpu_is_supported
since dpdk v17.08.eal: removed the
rte_malloc_virt2phy
function, replaced byrte_malloc_virt2iova
since v17.11.eal: made the
rte_config
struct andrte_eal_get_configuration
function private.mem: hid the internal
malloc_heap
structure and therte_malloc_heap.h
header.vfio: removed
rte_vfio_dma_map
andrte_vfio_dma_unmap
that have been marked as deprecated in release 19.05.rte_vfio_container_dma_map
andrte_vfio_container_dma_unmap
can be used as substitutes.pci: removed the following functions deprecated since dpdk v17.11:
eal_parse_pci_BDF
replaced byrte_pci_addr_parse
eal_parse_pci_DomBDF
replaced byrte_pci_addr_parse
rte_eal_compare_pci_addr
replaced byrte_pci_addr_cmp
The network structure
esp_tail
has been prefixed byrte_
.The network definitions of PPPoE ethertypes have been prefixed by
RTE_
.The network structure for MPLS has been prefixed by
rte_
.ethdev: changed
rte_eth_dev_infos_get
return value fromvoid
toint
to provide a way to report various error conditions.ethdev: changed
rte_eth_promiscuous_enable
andrte_eth_promiscuous_disable
return value fromvoid
toint
to provide a way to report various error conditions.ethdev: changed
rte_eth_allmulticast_enable
andrte_eth_allmulticast_disable
return value fromvoid
toint
to provide a way to report various error conditions.ethdev: changed

return value fromvoid
toint
to provide a way to report various error conditions.ethdev: changed
rte_eth_link_get
andrte_eth_link_get_nowait
return value fromvoid
toint
to provide a way to report various error conditions.ethdev: changed
rte_eth_macaddr_get
return value fromvoid
toint
to provide a way to report various error conditions.ethdev: changed
rte_eth_dev_owner_delete
return value fromvoid
toint
to provide a way to report various error conditions.ethdev: The deprecated function
rte_eth_dev_count
was removed. The functionrte_eth_dev_count_avail
is a drop-in replacement. If the intent is to iterate over ports,RTE_ETH_FOREACH_*
macros are better port iterators.ethdev:
RTE_FLOW_ITEM_TYPE_META
data endianness altered to host one. Due to the new dynamic metadata field in mbuf is host-endian either, there is a minor compatibility issue for applications in case of 32-bit values supported.ethdev: the tx_metadata mbuf field is moved to dynamic one.
PKT_TX_METADATA
flag is replaced withPKT_TX_DYNF_METADATA
.DEV_TX_OFFLOAD_MATCH_METADATA
offload flag is removed, now metadata support in PMD is engaged on dynamic field registration.event: The function
rte_event_eth_tx_adapter_enqueue
takes an additional input asflags
. FlagRTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST
which has been introduced in this release is used when all the packets enqueued in the Tx adapter are destined for the same Ethernet port and Tx queue.sched: The pipe nodes configuration parameters such as number of pipes, pipe queue sizes, pipe profiles, etc., are moved from port level structure to subport level. This allows different subports of the same port to have different configuration for the pipe nodes.
12.4. ABI Changes
policy: Please note the revisions to the ABI Policy introducing major ABI versions, with DPDK 19.11 becoming the first major version
v20
. ABI changes to add new features continue to be permitted in subsequent releases, with the condition that ABI compatibility with the major ABI version is maintained.net: The Ethernet address and other header definitions have changed attributes. They have been modified to be aligned on 2-byte boundaries. These changes should not impact normal usage because drivers naturally align the Ethernet header on receive and all known encapsulations preserve the alignment of the header.
security: The field
replay_win_sz
has been moved from the ipsec library basedrte_ipsec_sa_prm
structure to security library based structurerte_security_ipsec_xform
, which specify the anti-replay window size to enable sequence replay attack handling.ipsec: The field
replay_win_sz
has been removed from the structurerte_ipsec_sa_prm
as it has been added to the security library.ethdev: Added 32-bit fields for maximum LRO aggregated packet size, in struct
rte_eth_dev_info
for the port capability and in structrte_eth_rxmode
for the port configuration. Application should use the new field in structrte_eth_rxmode
to configure the requested size. PMD should use the new field in structrte_eth_dev_info
to report the supported port capability.
