RDMA/hns: Dump whole QP/CQ/MR resource in raw
Browse files Browse the repository at this point in the history 
Currently, some fields in the QP/CQ/MR resource can be dumped by
rdma-tool, but this 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.
