4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lijun Ou <ouli...@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.
