Subject: [PATCH v2 for-next 1/2] RDMA/hns: Dump whole QP/CQ/MR resource in raw
Date:   Thu, 31 Aug 2023 20:51:38 +0800

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, some fields in the QP/CQ/MR resource can be dumped by
rdma-tool, but these information is not enough. It is very
inconvenient to continue to expand on the current field, and it
will also introduce some trouble to parse these raw data.

This patch dump whole resource in raw to avoid the above problems.
