Common config:
    RQ:
      type: 2 stride size: 2048 size: 8
    CQ:
      stride size: 64 size: 1024
    RQs:
    ...

After:
$ devlink health diagnose pci/0000:00:0b.0 reporter rx
Common config:
    RQ:
      type: 2 stride size: 2048 size: 8
      CQ:
        stride size: 64 size: 1024
    RQs:
