Subject: [dpdk-dev] [PATCH v5 0/2] add Rx buffer size for rxq info structure
Date: Mon, 21 Sep 2020 21:22:36 +0800
Message-ID: <1600694558-19120-1-git-send-email-tangchengchang@huawei.com> (raw)
In-Reply-To: <1592483709-7076-1-git-send-email-tangchengchang@huawei.com>

In common practice, PMD configure the Rx buffer size which indicate the
buffer length could be used for HW in receiving packets according to the
data room size of the object in mempool. But in fact, the final value is
related to the specifications of HW, and its values will affect the number
of fragments in receiving packets when scatter is enabled. By the way,
some PMDs may force to enable scatter when the MTU is bigger than the HW
Rx buffer size.

At present, we have no way to expose relevant information to upper layer
users. So, add a field named rx_buf_size in rte_eth_rxq_info to indicate
the buffer size used in receiving packets for HW. And this field is
optional, so there is no need to forcibly update all PMDs.

This patchset also update testpmd, proc-info tools and add hns3 PMD
implementation.

v5:
  - squash oneline app patches and deprecation remove with ethdev patch

Chengchang Tang (2):
  ethdev: add a field for rxq info structure
  net/hns3: add Rx buffer size to Rx qinfo query
