The current mbuf scatter gather feature flag is too ambiguous, as it is not clear if input and/or output buffers can be scatter gather mbufs or not. Therefore, three new flags will replace this flag: - RTE_COMP_FF_OOP_SGL_IN_SGL_OUT - RTE_COMP_FF_OOP_SGL_IN_FB_OUT - RTE_COMP_FF_OOP_LB_IN_SGL_OUT Note that out-of-place flat buffers is supported by default and in-place is not supported by the library.

|
|

|
|
|
|

|
|
|
The text in the sections below explains how to update the release notes.
|
|
|
|
Use proper spelling, capitalization and punctuation in all sections.
|
|
|
|

|
|

New Features
|
|
------------
|
|
|
|
.. This section should contain new features added in this release.
|
|
Sample format:
|
|
|
|
* **Add a title in the past tense with a full stop.**
|
|
|
|
Add a short 1-2 sentence description in the past tense.
|
|
The description should be enough to allow someone scanning
|
|
the release notes to understand the new feature.
|
|
|
|
If the feature adds a lot of sub-features you can use a bullet list
|
|
like this:
|
|
|
|
* Added feature foo to do something.
|
|
* Enhanced feature bar to do something else.
|
|
|
|
Refer to the previous release notes for examples.

|
=========================================================
|
|
|
|
* **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.
|
|
|
|
* **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.**
|
|
|
|
``rte_eth_rx_descritpr_status`` and ``rte_eth_tx_descriptor_status``
|
|
are supported by fm10K.
|
|
|
|
* **Updated the enic driver.**
|
|
|
|
* Add support for mbuf fast free offload.
|
|
* Add low cycle count Tx handler for no-offload Tx (except mbuf fast free).
|
|
* 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.
