    Subject[PATCH AUTOSEL 5.7 240/388] RDMA/hns: Bugfix for querying qkey
    Date
    From: Lijun Ou <oulijun@huawei.com>

    [ Upstream commit 349be276509455ac2f19fa4051ed773082c6a27e ]

    The qkey queried through the query ud qp verb is a fixed value and it
    should be read from qp context.

    Fixes: 926a01dc000d ("RDMA/hns: Add QP operations support for hip08 SoC")
