The CQ raw restrack attributes come from the queue context maintained by
the ROCEE.
For example:
$ rdma res show cq dev hns_0 cqn 14 -dd -jp -r
[ {
"ifindex": 4,
"ifname": "hns_0",
"data": [ 1,0,0,0,7,0,0,0,0,0,0,0,0,82,6,0,0,82,6,0,0,82,6,0,
1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,
6,0,0,0,0,0,0,0 ]
} ]
