[PATCH 5.14 096/432] RDMA/hns: Dont overwrite supplied QP attributes

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2021-09-16 17:23:46
Also in: lkml
Subsystem: hisilicon roce driver, infiniband subsystem, the rest · Maintainers: Chengchang Tang, Junxian Huang, Jason Gunthorpe, Leon Romanovsky, Linus Torvalds

From: Leon Romanovsky <leonro@nvidia.com>

[ Upstream commit e66e49592b690d6abd537cc207b07a3db2f413d0 ]

QP attributes that were supplied by IB/core already have all parameters
set when they are passed to the driver. The drivers are not supposed to
change anything in struct ib_qp_init_attr.

Fixes: 66d86e529dd5 ("RDMA/hns: Add UD support for HIP09")
