      Description

      The logic currently in Lustre that loops reducing the queue sizes is silly.

      The ib_query_device() in kiblnd_hdev_get_attr() is done to save off the max_mr_size in the hdev.

      The code could save off max_qp_wr and use that cap the send queue calculations to avoid creating a QP above that limit.
