RDMA/hns: Support QP's restrack ops for hns driver
The QP restrack attributes come from the queue information maintained by the driver. For example: $ rdma res show qp link hns_0 lqpn 41 -jp -dd [ { "ifindex": 4, "ifname": "hns_0", "port": 1, "lqpn": 41, "rqpn": 40, "type": "RC", "state": "RTR", "rq-psn": 12474738, "sq-psn": 0, "path-mig-state": "ARMED", "pdn": 9, "pid": 1523, "comm": "ib_send_bw" }, "drv_sq_wqe_cnt": 128, "drv_sq_max_gs": 1, "drv_rq_wqe_cnt": 512, "drv_rq_max_gs": 2, "drv_ext_sge_sge_cnt": 0 } Link: https://lore.kernel.org/r/20220822104455.2311053-5-liangwenpeng@huawei.comSigned-off-by: Wenpeng Liang <liangwenpeng@huawei.com> Signed-off-by: Leon Romanovsky <leon@kernel.org>
