According to IB protocol, there are some cases that work requests must return the flush error completion status through the completion queue. Due to hardware limitation, the driver needs to assist the flush process. This patch adds the support of flush cqe for hip08 in the cases that needed, such as poll cqe, post send, post recv and aeqe handle. The patch also considered the compatibility between kernel and user space. Signed-off-by: Yixian Liu <liuyixian@huawei.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
