[PATCH for-next 01/10] RDMA/hns: Force rewrite inline flag of WQE

[Weihang Li]

From: Lang Cheng <chenglang@huawei.com>

When a non-inline WR reuses a WQE that was used for inline last time, the
remaining inline flag should be cleared.

[PATCH for-next 05/10] RDMA/hns: Delete unnecessary branch of hns_roce_v2_query_qp

[Weihang Li]

From: Yangyang Li <liyangyang20@huawei.com>

When query_qp is called by userspace, max_send_wr and max_send_sge are set
to 0 by the kernel driver. However, the userspace does not use these two
return values from the kernel driver, but uses its own calculated values.
So there is no need for special treatment.

[PATCH for-next 09/10] RDMA/hns: Simplify the judgment in hns_roce_v2_post_send()

[Weihang Li]

From: Yixing Liu <liuyixing1@huawei.com>

The QP type has been checked in check_send_valid(), if it's not RC, it will
process the UD/GSI branch.
