Subject[PATCH AUTOSEL 4.18 127/131] RDMA/hns: Update the data type of immediate data
Date
From: Lijun Ou <oulijun@huawei.com>

[ Upstream commit 0c4a0e2987a51415de73180ce9f389a99b3dddd1 ]

Because the data structure of hip08 is little endian, it needs to fix the
immediate field of wqe and cqe into __le32.
