Subject: [PATCH for-next 2/3] RDMA/hns: Bugfix for the missing assignment for dip_idx
Date: Wed, 25 Aug 2021 17:43:11 +0800 [thread overview]

In-Reply-To: <1629884592-23424-1-git-send-email-liangwenpeng@huawei.com>
From: Junxian Huang <huangjunxian4@hisilicon.com>
When the dgid-dip_idx mapping relationship exists, dip should be assigned.
