Resolved Issues
|
|
---------------
|
|
|
|
EAL
|
|
~~~
|
|
|
|
* **eal/linux: Fixed epoll timeout.**
|
|
|
|
Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
|
|
underlying call to ``epoll_wait()`` timed out.
|
|
|
|
|
|
Drivers
|
|
~~~~~~~
|
|
|
|
* **igb: Fixed IEEE1588 frame identification in I210.**
|
|
|
|
Fixed issue where the flag PKT_RX_IEEE1588_PTP was not being set
|
|
in Intel I210 NIC, as EtherType in RX descriptor is in bits 8:10 of
|
|
Packet Type and not in the default bits 0:2.
|
|
|
|
* **igb: Fixed VF start with PF stopped.**
|
|
|
|
VF needs the PF interrupt support initialized even if not started.
|
|
|
|
* **igb: Fixed VF MAC address when using with DPDK PF.**
|
|
|
|
Assign a random MAC address in VF when not assigned by PF.
|
|
|
|
* **ixgbe: Fixed issue with X550 DCB.**
|
|
|
|
Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
|
|
with user priority 6 or 7 was injected to the NIC, then the NIC would only
|
|
put 3 packets into the queue. There was also a similar issue for 4 TCs.
|
|
|
|
* **ixgbe: Removed burst size restriction of vector RX.**
|
|
|
|
Fixed issue where a burst size less than 32 didn't receive anything.
|
|
|
|
* **ixgbe: Fixed VF start with PF stopped.**
|
|
|
|
VF needs the PF interrupt support initialized even if not started.
|
|
|
|
* **ixgbe: Fixed TX hang when RS distance exceeds HW limit.**
|
|
|
|
Fixed an issue when TX queue can hang when a lot of highly fragmented
|
|
packets have to be sent.
|
|
As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
|
|
then to 32 to comply with HW restrictions.
|
|
|
|
* **i40e: Fixed base driver allocation when not using first numa node.**
|
|
|
|
Fixed i40e issue that occurred when a DPDK application didn't initialize
|
|
ports if memory wasn't available on socket 0.
|
|
|
|
* **i40e: Fixed maximum of 64 queues per port.**
|
|
|
|
Fixed the issue in i40e of cannot supporting more than 64 queues per port,
|
|
though hardware actually supports that. The real number of queues may vary,
|
|
as long as the total number of queues used in PF, VFs, VMDq and FD does not
|
|
exceeds the hardware maximum.
|
|
|
|
* **i40e: Fixed statistics of packets.**
|
|
|
|
Added discarding packets on VSI to the stats and rectify the old statistics.
|
|
|
|
* **i40e: Fixed issue of not freeing memzone.**
|
|
|
|
Fixed the issue of not freeing memzone in the call to free the memory for
|
|
adminq DMA.
|
|
|
|
* **mlx: Fixed driver loading.**
|
|
|
|
The mlx drivers were unable to load when built as a shared library,
|
|
due to a missing symbol in mempool library.
|
|
|
|
* **vhost: Fixed Qemu shutdown.**
|
|
|
|
Fixed issue with libvirt ``virsh destroy`` not killing the VM.
|
|
|
|
* **virtio: Fixed crash after changing link state.**
|
|
|
|
Fixed io permission in the interrupt handler.
|
|
|
|
* **virtio: Fixed crash when releasing queue.**
|
|
|
|
Fixed issue when releasing null control queue.
|
|
|
|
|
|
Libraries
|
|
~~~~~~~~~
|
|
|
|
* **hash: Fixed memory allocation of Cuckoo Hash key table.**
|
|
|
|
Fixed issue where an incorrect Cuckoo Hash key table size could be
|
|
calculated limiting the size to 4GB.
|
|
|
|
* **hash: Fixed incorrect lookup if key is all zero.**
|
|
|
|
Fixed issue in hash library that occurred if an all zero
|
|
key was not added in the table and the key was looked up,
|
|
resulting in an incorrect hit.
|
|
|
|
* **hash: Fixed thread scaling by reducing contention.**
|
|
|
|
Fixed issue in hash library where, using multiple cores with
|
|
hardware transactional memory support, thread scaling did not work,
|
|
due to the global ring that is shared by all cores.
|
|
|
|
|
|
Examples
|
|
~~~~~~~~
|
|
|
|
* **vhost_xen: Fixed compile error.**

|
|
|
|
|
|
Known Issues
|
|
------------
|
|
|
|
* Some drivers do not fill the packet type when receiving.
|
|
As the l3fwd example application requires this info, the i40e vector
|
|
driver must be disabled to benefit of the packet type with i40e.
|
|
|
|
|
|
API Changes
|
|
-----------
|
|
|
|
* The deprecated flow director API is removed.
|
|
It was replaced by rte_eth_dev_filter_ctrl().
|
|
|
|
* The dcb_queue is renamed to dcb_tc in following dcb configuration
|
|
structures: rte_eth_dcb_rx_conf, rte_eth_dcb_tx_conf,
|
|
rte_eth_vmdq_dcb_conf, rte_eth_vmdq_dcb_tx_conf.
|
|
|
|
* The rte_eth_rx_queue_count() function now returns "int" instead of "uint32_t"
|
|
to allow the use of negative values as error codes on return.
|
|
|
|
* The function rte_eal_pci_close_one() is removed.
|
|
It was replaced by rte_eal_pci_detach().
|
|
|
|
* The deprecated ACL API ipv4vlan is removed.
|
|
|
|
* The deprecated hash function rte_jhash2() is removed.
|
|
It was replaced by rte_jhash_32b().
|
|
|
|
* The deprecated KNI functions are removed:
|
|
rte_kni_create(), rte_kni_get_port_id() and rte_kni_info_get().
|
|
|
|
* The deprecated ring PMD functions are removed:
|
|
rte_eth_ring_pair_create() and rte_eth_ring_pair_attach().
|
|
|
|
* The devargs union field virtual is renamed to virt for C++ compatibility.
|
|
|
|
ABI Changes
|
|
-----------
|
|
|
|
* The EAL and ethdev structures rte_intr_handle and rte_eth_conf were changed
|
|
to support Rx interrupt. It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
|
|
|
|
* The ethdev flow director entries for SCTP were changed.
|
|
It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
|
|
|
|
* The ethdev flow director structure rte_eth_fdir_flow_ext structure is changed.
|
|
New fields are added to support flow director filtering in VF.
|
|
|
|
* The size of the ethdev structure rte_eth_hash_filter_info is changed
|
|
by adding a new element rte_eth_input_set_conf in an union.
|
|
|
|
* The new fields rx_desc_lim and tx_desc_lim are added into rte_eth_dev_info
|
|
structure.
|
|
|
|
* For debug builds, the functions rte_eth_rx_burst(), rte_eth_tx_burst()
|
|
rte_eth_rx_descriptor_done() and rte_eth_rx_queue_count() will
|
|
no longer be separate functions in the DPDK libraries. Instead, they will
|
|
only be present in the rte_ethdev.h header file.
|
|
|
|
* The maximum number of queues per port CONFIG_RTE_MAX_QUEUES_PER_PORT is
|
|
increased to 1024.
|
|
|
|
* The mbuf structure was changed to support unified packet type.
|
|
It was already done in 2.1 for CONFIG_RTE_NEXT_ABI.
|
|
|
|
* The dummy malloc library is removed. The content was moved into EAL in 2.1.
|
|
|
|
* The LPM structure is changed. The deprecated field mem_location is removed.
|
|
|
|
* librte_table LPM: A new parameter to hold the table name will be added to
|
|
the LPM table parameter structure.
|
|
|
|
* librte_table hash: The key mask parameter is added to the hash table
|
|
parameter structure for 8-byte key and 16-byte key extendible bucket
|
|
and LRU tables.
|
|
|
|
* librte_port: Macros to access the packet meta-data stored within the packet
|
|
buffer has been adjusted to cover the packet mbuf structure.
|
|
|
|
* librte_cfgfile: Allow longer names and values by increasing the constants
|
|
CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
