Subject: [dpdk-dev] [PATCH v2] doc: add new field to rxq info struct
Date: Thu, 6 Aug 2020 12:00:46 +0800
Message-ID: <1596686446-8138-2-git-send-email-tangchengchang@huawei.com> (raw)
In-Reply-To: <1596686446-8138-1-git-send-email-tangchengchang@huawei.com>

Struct rte_eth_rxq_info will be modified to include a new field, indicating
the size of each buffer that could be used for hw to receive packets. Add
this field to rte_eth_rxq_info to expose relevant information to upper
layer users/application.

For more details:

   break the ABI checks, that is why change is planned for 20.11.
   The list of internal APIs are mainly ones listed in ``rte_ethdev_driver.h``.
+* ethdev: A new field will be added to the public data structure
+  ``rte_eth_rxq_info`` to indicate the buffer size used in receiving packets
+  for HW. When receive packets, HW DMA won't exceed this size. And it will
+  affect the number of fragments in receiving packets when scatter is enabled.
+  So, add this field to ``rte_eth_rxq_info`` to expose relevant information to
+  upper layer user/application.
+  This change is planned for 20.11. For more details:

 * traffic manager: All traffic manager API's in ``rte_tm.h`` were mistakenly made
   ABI stable in the v19.11 release. The TM maintainer and other contributors have
   agreed to keep the TM APIs as experimental in expectation of additional spec
