|
* eal: several API and ABI changes are planned for ``rte_devargs`` in v18.02.
|
2017-08-04 13:29:00 +00:00
|
|
|
The format of device command line parameters will change. The bus will need
|
|
|
|
|
to be explicitly stated in the device declaration. The enum ``rte_devtype``
|
|
|
|
|
was used to identify a bus and will disappear.
|
|
|
|
|
The structure ``rte_devargs`` will change.
|
|
|
|
|
The ``rte_devargs_list`` will be made private.
|
|
|
|
|
The following functions are deprecated starting from 17.08 and will either be
|
2017-11-08 09:53:27 +00:00
|
|
|
modified or removed in 18.02:
|
2017-08-04 13:29:00 +00:00
|
|
|
|
|
|
|
|
- ``rte_eal_devargs_add``
|
|
|
|
|
- ``rte_eal_devargs_type_count``
|
|
|
|
|
- ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse``
|

|
|
|
* pci: Several exposed functions are misnamed.
|
|
|
|
|
The following functions are deprecated starting from v17.11 and are replaced:
|
|
|
|
|
|
2017-10-26 10:06:00 +00:00
|
|
|
- ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
|
|
|
|
|
- ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
|
2017-10-26 10:05:58 +00:00
|
|
|
- ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
|
|
|
|
|
|
2017-10-17 14:24:14 +00:00
|
|
|
* ethdev: a new Tx and Rx offload API was introduced on 17.11.
|
|
|
|
|
In the new API, offloads are divided into per-port and per-queue offloads.
|
|
|
|
|
Offloads are disabled by default and enabled per application request.
|
|
|
|
|
The old offloads API is target to be deprecated on 18.05. This includes:
|
|
|
|
|
|
|
|
|
|
- removal of ``ETH_TXQ_FLAGS_NO*`` flags.
|
|
|
|
|
- removal of ``txq_flags`` field from ``rte_eth_txconf`` struct.
|
|
|
|
|
- removal of the offloads bit-field from ``rte_eth_rxmode`` struct.

|
2016-12-21 14:51:19 +00:00
|
|
|
* ethdev: the legacy filter API, including
|
|
|
|
|
``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
|
|
|
|
|
as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
|
|
|
|
|
HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
|
|
|
|
|
PMDs that implement the latter.
|
|
|
|
|
Target release for removal of the legacy API will be defined once most
|
|
|
|
|
PMDs have switched to rte_flow.

2017-11-03 15:24:23 +00:00
|
|
|
* i40e: The default flexible payload configuration which extracts the first 16
|
|
|
|
|
bytes of the payload for RSS will be deprecated starting from 18.02. If
|
|
|
|
|
required the previous behavior can be configured using existing flow
|
|
|
|
|
director APIs. There is no ABI/API break. This change will just remove a
|
|
|
|
|
global configuration setting and require explicit configuration.
|
|
|
|
|
|
2017-08-04 13:19:40 +00:00
|
|
|
* librte_meter: The API will change to accommodate configuration profiles.
|
|
|
|
|
Most of the API functions will have an additional opaque parameter.
|
2017-09-11 13:39:13 +00:00
|
|
|
|
|
|
|
|
* ring: The alignment constraints on the ring structure will be relaxed
|
|
|
|
|
to one cache line instead of two, and an empty cache line padding will
|
|
|
|
|
be added between the producer and consumer structures. The size of the
|
|
|
|
|
structure and the offset of the fields will remain the same on
|
|
|
|
|
platforms with 64B cache line, but will change on other platforms.
