New Features
------------
-.. This section should contain new features added in this release.
- Sample format:
+* **Added new RSS offload types for IB_BTH in RSS flow.**
- * **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.
-
- Suggested order in release notes items:
- * Core libs (EAL, mempool, ring, mbuf, buses)
- * Device abstraction libs and PMDs (ordered alphabetically by vendor name)
- - ethdev (lib, PMDs)
- - cryptodev (lib, PMDs)
- - eventdev (lib, PMDs)
- - etc
- * Other libs
- * Apps, Examples, Tools (if significant)
-
- This section is a comment. Do not overwrite or remove it.
- Also, make sure to start the actual text at the margin.
- =======================================================
+ Added ``RTE_ETH_RSS_IB_BTH`` macro so that the IB BTH header can be used as
+ input set for RSS.
