1. #1: The first patch supports dumping QP/CQ/MR context entirely in raw
data with rdma-tool.
2. #2: The second patch supports query of HW stats with rdma-tool.
3. #3: The last patch supports query of SW stats with rdma-tool.

2.30.0
From: Chengchang Tang <[email protected]>
Currently, some fields in the QP/CQ/MR resource can be dumped by
rdma-tool, but these informations are 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.
