From 6f7aa1029f8efc87457b7c5e7d6c3bcd12af101b Mon Sep 17 00:00:00 2001 From: Wenpeng Liang Date: Mon, 29 Aug 2022 18:50:19 +0800 Subject: [PATCH] RDMA/hns: Fix wrong fixed value of qp->rq.wqe_shift [ Upstream commit 0c8b5d6268d92d141bfd64d21c870d295a84dee1 ] The value of qp->rq.wqe_shift of HIP08 is always determined by the number of sge. So delete the wrong branch.
