customize objects population and allocate contiguous
block of objects if underlying driver supports it.
-* mbuf: The control mbuf API will be removed in v18.05. The impacted
- functions and macros are:
-
- - ``rte_ctrlmbuf_init()``
- - ``rte_ctrlmbuf_alloc()``
- - ``rte_ctrlmbuf_free()``
- - ``rte_ctrlmbuf_data()``
- - ``rte_ctrlmbuf_len()``
- - ``rte_is_ctrlmbuf()``
- - ``CTRL_MBUF_FLAG``
-
- The packet mbuf API should be used as a replacement.
-
* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
definition in line with the ethdev TM and MTR APIs. Currently, this field
is defined in librte_sched in a non-generic way. The new generic format
* 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:
+ The old ethdev - drivers offload interface will be deprecated on 18.05.
+ This includes:
+ - removal of the conversion in ethdev from new offloading API to old API for drivers.
+
+ In later releases the old offloading API will be deprecated, which will include:
- 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.
The new API add rss_level field to ``rte_eth_rss_conf`` to enable a choice
of RSS hash calculation on outer or inner header of tunneled packet.
-* ethdev: Currently, if the rte_eth_rx_burst() function returns a value less
- than *nb_pkts*, the application will assume that no more packets are present.
- Some of the hw queue based hardware can only support smaller burst for RX
- and TX and thus break the expectation of the rx_burst API. Similar is the
- case for TX burst as well as ring sizes. ``rte_eth_dev_info`` will be added
- with following new parameters so as to support semantics for drivers to
- define a preferred size for Rx/Tx burst and rings.
-
- - Member ``struct preferred_size`` would be added to enclose all preferred
- size to be fetched from driver/implementation.
- - Members ``uint16_t rx_burst``, ``uint16_t tx_burst``, ``uint16_t rx_ring``,
- and ``uint16_t tx_ring`` would be added to ``struct preferred_size``.
-
* ethdev: A work is being planned for 18.05 to expose VF port representors
as a mean to perform control and data path operation on the different VFs.
As VF representor is an ethdev port, new fields are needed in order to map
between the VF representor and the VF or the parent PF. Those new fields
are to be included in ``rte_eth_dev_info`` struct.
-* ethdev: The prototype and the behavior of
- ``dev_ops->eth_mac_addr_set()`` will change in v18.05. A return code
- will be added to notify the caller if an error occurred in the PMD. In
- ``rte_eth_dev_default_mac_addr_set()``, the new default MAC address
- will be copied in ``dev->data->mac_addrs[0]`` only if the operation is
- successful. This modification will only impact the PMDs, not the
- applications.
-
* 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.
-
-* 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.
