[ Upstream commit ab6f7248cc446b85fe9e31091670ad7c4293d7fd ]
The maximum number of retransmission should be returned when querying QP, not the value of retransmission counter.
Fixes: 99fcf82521d9 ("RDMA/hns: Fix the wrong value of rnr_retry when querying qp") Fixes: 926a01dc000d ("RDMA/hns: Add QP operations support for hip08 SoC") Link: https://lore.kernel.org/r/1606382977-21431-1-git-send-email-liweihang@huawei...
