From 4303e61264c45cb535255c5b76400f5c4ab1305d Mon Sep 17 00:00:00 2001 From: Junxian Huang Date: Wed, 25 Aug 2021 17:43:10 +0800 Subject: RDMA/hns: Bugfix for data type of dip_idx dip_idx is associated with qp_num whose data type is u32. However, dip_idx is incorrectly defined as u8 data in the hns_roce_dip struct, which leads to data truncation during value assignment.
