The restrack attributes of QP come from the QPC and the queue information
maintained by the software code.

I have a feeling that this is abuse of our vendor specific attributes.
Why don't you use RDMA_NLDEV_ATTR_RES_RAW for such huge dumps?

I forgot to add the output of rdmatool in the commit message,
it will be added in the next version.

I will reconsider the attributes that should be dumped. I will use
RDMA_NLDEV_ATTR_RES for key attributes and RDMA_NLDEV_ATTR_RES_RAW
for huge dumps.
